The image files are not actually JPEG, thus we first need to save them in the correct format for Turicreate

from PIL import Image
+import glob
+
+
+folders = ["default","smoke","fire"]
+for folder in folders:
+  n = 1
+  for file in glob.glob("./data/data/img_data/train/" + folder + "/*.jpg"):
+    im = Image.open(file)
+    rgb_im = im.convert('RGB')
+    rgb_im.save((folder + "/" + str(n) + ".jpg"), quality=100)
+    n +=1 
+  for file in glob.glob("./data/data/img_data/train/" + folder + "/*.jpg"):
+    im = Image.open(file)
+    rgb_im = im.convert('RGB')
+    rgb_im.save((folder + "/" + str(n) + ".jpg"), quality=100)
+    n +=1
+

+
+


!mkdir train
+!mv default ./train

In this tutorial we will build a fake news detecting app from scratch, using Turicreate for the machine learning model and SwiftUI for building the app

Note: These commands are written as if you are running a jupyter notebook.

Building the Machine Learning Model

Data Gathering

To build a classifier, you need a lot of data. George McIntire (GH: @joolsa) has created a wonderful dataset containing the headline, body and wheter it is fake or real. Whenever you are looking for a dataset, always try searching on Kaggle and GitHub before you start building your own

Dependencies

I used a Google Colab instance for training my model. If you also plan on using Google Colab then I reccomend choosing a GPU Instance (It is Free) This allows you to train the model on the GPU. Turicreat is built on top of Apache's MXNet Framework, for us to use GPU we need to install a CUDA compatible MXNet package.

!pip install turicreate
+!pip uninstall -y mxnet
+!pip install mxnet-cu100==1.4.0.post0
+

+
+

If you do not wish to train on GPU or are running it on your computer, you can ignore the last two lines

Downloading the Dataset

!wget -q "https://github.com/joolsa/fake_real_news_dataset/raw/master/fake_or_real_news.csv.zip"
+!unzip fake_or_real_news.csv.zip
+

+
+

Model Creation

import turicreate as tc
+tc.config.set_num_gpus(-1) # If you do not wish to use GPUs, set it to 0
+

+
+
dataSFrame = tc.SFrame('fake_or_real_news.csv')
+

+
+

The dataset contains a column named "X1", which is of no use to us. Therefore, we simply drop it

dataSFrame.remove_column('X1')
+

+
+

Splitting Dataset

train, test = dataSFrame.random_split(.9)
+

+
+

Training

model = tc.text_classifier.create(
+    dataset=train,
+    target='label',
+    features=['title','text']
+)
+

+

Testing the Model

est_predictions = model.predict(test)
+accuracy = tc.evaluation.accuracy(test['label'], test_predictions)
+print(f'Topic classifier model has a testing accuracy of {accuracy*100}% ', flush=True)
+

+
+
Topic classifier model has a testing accuracy of 92.3076923076923%
+

+

We have just created our own Fake News Detection Model which has an accuracy of 92%!

example_text = {"title": ["Middling ‘Rise Of Skywalker’ Review Leaves Fan On Fence About Whether To Threaten To Kill Critic"], "text": ["Expressing ambivalence toward the relatively balanced appraisal of the film, Star Wars fan Miles Ariely admitted Thursday that an online publication’s middling review of The Rise Of Skywalker had left him on the fence about whether he would still threaten to kill the critic who wrote it. “I’m really of two minds about this, because on the one hand, he said the new movie fails to live up to the original trilogy, which makes me at least want to throw a brick through his window with a note telling him to watch his back,” said Ariely, confirming he had already drafted an eight-page-long death threat to Stan Corimer of the website Screen-On Time, but had not yet decided whether to post it to the reviewer’s Facebook page. “On the other hand, though, he commended J.J. Abrams’ skillful pacing and faithfulness to George Lucas’ vision, which makes me wonder if I should just call the whole thing off. Now, I really don’t feel like camping outside his house for hours. Maybe I could go with a response that’s somewhere in between, like, threatening to kill his dog but not everyone in his whole family? I don’t know. This is a tough one.” At press time, sources reported that Ariely had resolved to wear his Ewok costume while he murdered the critic in his sleep."]}

Building the App using SwiftUI

Initial Setup

First we create a single view app (make sure you check the use SwiftUI button)

Then we copy our .mlmodel file to our project (Just drag and drop the file in the XCode Files Sidebar)

Our ML Model does not take a string directly as an input, rather it takes bag of words as an input. DescriptionThe bag-of-words model is a simplifying representation used in NLP, in this text is represented as a bag of words, without any regatd of grammar or order, but noting multiplicity

We define our bag of words function

func bow(text: String) -> [String: Double] {
+        var bagOfWords = [String: Double]()
+        
+        let tagger = NSLinguisticTagger(tagSchemes: [.tokenType], options: 0)
+        let range = NSRange(location: 0, length: text.utf16.count)
+        let options: NSLinguisticTagger.Options = [.omitPunctuation, .omitWhitespace]
+        tagger.string = text
+        
+        tagger.enumerateTags(in: range, unit: .word, scheme: .tokenType, options: options) { _, tokenRange, _ in
+            let word = (text as NSString).substring(with: tokenRange)
+            if bagOfWords[word] != nil {
+                bagOfWords[word]! += 1
+            } else {
+                bagOfWords[word] = 1
+            }
+        }
+        
+        return bagOfWords
+    }
+

+
+

We also declare our variables

@State private var title: String = ""
+@State private var headline: String = ""
+@State private var alertTitle = ""
+@State private var alertText = ""
+@State private var showingAlert = false
+

+
+

Finally, we implement a simple function which reads the two text fields, creates their bag of words representation and displays an alert with the appropriate result

Complete Code

import SwiftUI
+
+struct ContentView: View {
+    @State private var title: String = ""
+    @State private var headline: String = ""
+    
+    @State private var alertTitle = ""
+    @State private var alertText = ""
+    @State private var showingAlert = false
+    
+    var body: some View {
+        NavigationView {
+            VStack(alignment: .leading) {
+                Text("Headline").font(.headline)
+                TextField("Please Enter Headline", text: $title)
+                    .lineLimit(nil)
+                Text("Body").font(.headline)
+                TextField("Please Enter the content", text: $headline)
+                .lineLimit(nil)
+            }
+                .navigationBarTitle("Fake News Checker")
+            .navigationBarItems(trailing:
+                Button(action: classifyFakeNews) {
+                    Text("Check")
+                })
+            .padding()
+                .alert(isPresented: $showingAlert){
+                    Alert(title: Text(alertTitle), message: Text(alertText), dismissButton: .default(Text("OK")))
+            }
+        }
+        
+    }
+    
+    func classifyFakeNews(){
+        let model = FakeNews()
+        let myTitle = bow(text: title)
+        let myText = bow(text: headline)
+        do {
+            let prediction = try model.prediction(title: myTitle, text: myText)
+            alertTitle = prediction.label
+            alertText = "It is likely that this piece of news is \(prediction.label.lowercased())."
+            print(alertText)
+        } catch {
+            alertTitle = "Error"
+            alertText = "Sorry, could not classify if the input news was fake or not."
+        }
+        
+        showingAlert = true
+    }
+    func bow(text: String) -> [String: Double] {
+        var bagOfWords = [String: Double]()
+        
+        let tagger = NSLinguisticTagger(tagSchemes: [.tokenType], options: 0)
+        let range = NSRange(location: 0, length: text.utf16.count)
+        let options: NSLinguisticTagger.Options = [.omitPunctuation, .omitWhitespace]
+        tagger.string = text
+        
+        tagger.enumerateTags(in: range, unit: .word, scheme: .tokenType, options: options) { _, tokenRange, _ in
+            let word = (text as NSString).substring(with: tokenRange)
+            if bagOfWords[word] != nil {
+                bagOfWords[word]! += 1
+            } else {
+                bagOfWords[word] = 1
+            }
+        }
+        
+        return bagOfWords
+    }
+}

In this tutorial you will learn about polynomial regression and how you can implement it in Tensorflow.

In this, we will be performing polynomial regression using 5 types of equations -

  • Linear
  • Quadratic
  • Cubic
  • Quartic
  • Quintic

Regression

What is Regression?

Regression is a statistical measurement that is used to try to determine the relationship between a dependent variable (often denoted by Y), and series of varying variables (called independent variables, often denoted by X ).

What is Polynomial Regression

This is a form of Regression Analysis where the relationship between Y and X is denoted as the nth degree/power of X. Polynomial regression even fits a non-linear relationship (e.g when the points don't form a straight line).

Imports

import tensorflow.compat.v1 as tf
+tf.disable_v2_behavior()
+import matplotlib.pyplot as plt
+import numpy as np
+import pandas as pd
+

+
+

Dataset

Creating Random Data

Even though in this tutorial we will use a Position Vs Salary datasset, it is important to know how to create synthetic data

To create 50 values spaced evenly between 0 and 50, we use NumPy's linspace funtion

linspace(lower_limit, upper_limit, no_of_observations)

x = np.linspace(0, 50, 50)
+y = np.linspace(0, 50, 50)
+

+
+

We use the following function to add noise to the data, so that our values

x += np.random.uniform(-4, 4, 50)
+y += np.random.uniform(-4, 4, 50)
+

+
+

Position vs Salary Dataset

We will be using https://drive.google.com/file/d/1tNL4jxZEfpaP4oflfSn6pIHJX7Pachm9/view (Salary vs Position Dataset)

!wget --no-check-certificate 'https://docs.google.com/uc?export=download&id=1tNL4jxZEfpaP4oflfSn6pIHJX7Pachm9' -O data.csv
+

+
+
df = pd.read_csv("data.csv")
+

+
+
df # this gives us a preview of the dataset we are working with
+

+
+
| Position          | Level | Salary  |
+|-------------------|-------|---------|
+| Business Analyst  | 1     | 45000   |
+| Junior Consultant | 2     | 50000   |
+| Senior Consultant | 3     | 60000   |
+| Manager           | 4     | 80000   |
+| Country Manager   | 5     | 110000  |
+| Region Manager    | 6     | 150000  |
+| Partner           | 7     | 200000  |
+| Senior Partner    | 8     | 300000  |
+| C-level           | 9     | 500000  |
+| CEO               | 10    | 1000000 |
+

+
+

We convert the salary column as the ordinate (y-cordinate) and level column as the abscissa

abscissa = df["Level"].to_list() # abscissa = [1,2,3,4,5,6,7,8,9,10]
+ordinate = df["Salary"].to_list() # ordinate = [45000,50000,60000,80000,110000,150000,200000,300000,500000,1000000]
+

+
+
n = len(abscissa) # no of observations
+plt.scatter(abscissa, ordinate)
+plt.ylabel('Salary')
+plt.xlabel('Position')
+plt.title("Salary vs Position")
+plt.show()
+

+
+

Defining Stuff

X = tf.placeholder("float")
+Y = tf.placeholder("float")
+

+
+

Defining Variables

We first define all the coefficients and constant as tensorflow variables haveing a random intitial value

a = tf.Variable(np.random.randn(), name = "a")
+b = tf.Variable(np.random.randn(), name = "b")
+c = tf.Variable(np.random.randn(), name = "c")
+d = tf.Variable(np.random.randn(), name = "d")
+e = tf.Variable(np.random.randn(), name = "e")
+f = tf.Variable(np.random.randn(), name = "f")
+

+
+

Model Configuration

learning_rate = 0.2
+no_of_epochs = 25000
+

+
+

Equations

deg1 = a*X + b
+deg2 = a*tf.pow(X,2) + b*X + c
+deg3 = a*tf.pow(X,3) + b*tf.pow(X,2) + c*X + d
+deg4 = a*tf.pow(X,4) + b*tf.pow(X,3) + c*tf.pow(X,2) + d*X + e
+deg5 = a*tf.pow(X,5) + b*tf.pow(X,4) + c*tf.pow(X,3) + d*tf.pow(X,2) + e*X + f
+

+
+

Cost Function

We use the Mean Squared Error Function

mse1 = tf.reduce_sum(tf.pow(deg1-Y,2))/(2*n)
+mse2 = tf.reduce_sum(tf.pow(deg2-Y,2))/(2*n)
+mse3 = tf.reduce_sum(tf.pow(deg3-Y,2))/(2*n)
+mse4 = tf.reduce_sum(tf.pow(deg4-Y,2))/(2*n)
+mse5 = tf.reduce_sum(tf.pow(deg5-Y,2))/(2*n)
+

+
+

Optimizer

We use the AdamOptimizer for the polynomial functions and GradientDescentOptimizer for the linear function

optimizer1 = tf.train.GradientDescentOptimizer(learning_rate).minimize(mse1)
+optimizer2 = tf.train.AdamOptimizer(learning_rate).minimize(mse2)
+optimizer3 = tf.train.AdamOptimizer(learning_rate).minimize(mse3)
+optimizer4 = tf.train.AdamOptimizer(learning_rate).minimize(mse4)
+optimizer5 = tf.train.AdamOptimizer(learning_rate).minimize(mse5)
+

+
+
init=tf.global_variables_initializer()
+

+
+

Model Predictions

For each type of equation first we make the model predict the values of the coefficient(s) and constant, once we get these values we use it to predict the Y values using the X values. We then plot it to compare the actual data and predicted line.

Notes

Overfitting

> Overfitting refers to a model that models the training data too well.Overfitting happens when a model learns the detail and noise in the training data to the extent that it negatively impacts the performance of the model on new data. This means that the noise or random fluctuations in the training data is picked up and learned as concepts by the model. The problem is that these concepts do not apply to new data and negatively impact the models ability to generalize.

Source: Machine Learning Mastery

Basically if you train your machine learning model on a small dataset for a really large number of epochs, the model will learn all the deformities/noise in the data and will actually think that it is a normal part. Therefore when it will see some new data, it will discard that new data as noise and will impact the accuracy of the model in a negative manner

This was tested on TF 2.x and works as of 2019-12-10

If you want to understand how to make your own custom image classifier, please refer to my previous post.

If you followed my last post, then you created a model which took an image of dimensions 50x50 as an input.

First we import the following if we have not imported these before

import cv2
+import os
+

+
+

Then we read the file using OpenCV.

image=cv2.imread(imagePath)
+

+
+

The cv2. imread() function returns a NumPy array representing the image. Therefore, we need to convert it before we can use it.

image_from_array = Image.fromarray(image, 'RGB')
+

+
+

Then we resize the image

size_image = image_from_array.resize((50,50))
+

+
+

After this we create a batch consisting of only one image

p = np.expand_dims(size_image, 0)
+

+
+

We then convert this uint8 datatype to a float32 datatype

img = tf.cast(p, tf.float32)
+

+
+

Finally we make the prediction

print(['Infected','Uninfected'][np.argmax(model.predict(img))])
+

+
+

Infected

Dataset

Fetching the Data

!wget ftp://lhcftp.nlm.nih.gov/Open-Access-Datasets/Malaria/cell_images.zip
+!unzip cell_images.zip
+

+
+

Processing the Data

We resize all the images as 50x50 and add the numpy array of that image as well as their label names (Infected or Not) to common arrays.

data = []
+labels = []
+
+Parasitized = os.listdir("./cell_images/Parasitized/")
+for parasite in Parasitized:
+    try:
+        image=cv2.imread("./cell_images/Parasitized/"+parasite)
+        image_from_array = Image.fromarray(image, 'RGB')
+        size_image = image_from_array.resize((50, 50))
+        data.append(np.array(size_image))
+        labels.append(0)
+    except AttributeError:
+        print("")
+
+Uninfected = os.listdir("./cell_images/Uninfected/")
+for uninfect in Uninfected:
+    try:
+        image=cv2.imread("./cell_images/Uninfected/"+uninfect)
+        image_from_array = Image.fromarray(image, 'RGB')
+        size_image = image_from_array.resize((50, 50))
+        data.append(np.array(size_image))
+        labels.append(1)
+    except AttributeError:
+        print("")
+

+
+

Splitting Data

df = np.array(data)
+labels = np.array(labels)
+(X_train, X_test) = df[(int)(0.1*len(df)):],df[:(int)(0.1*len(df))]
+(y_train, y_test) = labels[(int)(0.1*len(labels)):],labels[:(int)(0.1*len(labels))]
+

+
+
s=np.arange(X_train.shape[0])
+np.random.shuffle(s)
+X_train=X_train[s]
+y_train=y_train[s]
+X_train = X_train/255.0
+

+
+

Model

Creating Model

By creating a sequential model, we create a linear stack of layers.

Note: The input shape for the first layer is 50,50 which corresponds with the sizes of the resized images

model = models.Sequential()
+model.add(layers.Conv2D(filters=16, kernel_size=2, padding='same', activation='relu', input_shape=(50,50,3)))
+model.add(layers.MaxPooling2D(pool_size=2))
+model.add(layers.Conv2D(filters=32,kernel_size=2,padding='same',activation='relu'))
+model.add(layers.MaxPooling2D(pool_size=2))
+model.add(layers.Conv2D(filters=64,kernel_size=2,padding="same",activation="relu"))
+model.add(layers.MaxPooling2D(pool_size=2))
+model.add(layers.Dropout(0.2))
+model.add(layers.Flatten())
+model.add(layers.Dense(500,activation="relu"))
+model.add(layers.Dropout(0.2))
+model.add(layers.Dense(2,activation="softmax"))#2 represent output layer neurons 
+model.summary()
+

+
+

Compiling Model

We use the adam optimiser as it is an adaptive learning rate optimization algorithm that's been designed specifically for training deep neural networks, which means it changes its learning rate automaticaly to get the best results

model.compile(optimizer="adam",
+              loss="sparse_categorical_crossentropy", 
+             metrics=["accuracy"])
+

+
+

Training Model

We train the model for 10 epochs on the training data and then validate it using the testing data

history = model.fit(X_train,y_train, epochs=10, validation_data=(X_test,y_test))
+

+
+

4 minute readCreated on December 8, 2019Last modified on January 18, 2020
Creating a Custom Image Classifier using Tensorflow 2.x and Keras for Detecting Malaria
Done during Google Code-In. Org: Tensorflow.
Imports
%tensorflow_version 2.x #This is for telling Colab that you want to use TF 2.0, ignore if running on local machine
+
+from PIL import Image # We use the PIL Library to resize images
+import numpy as np
+import os
+import cv2
+import tensorflow as tf
+from tensorflow.keras import datasets, layers, models
+import pandas as pd
+import matplotlib.pyplot as plt
+from keras.models import Sequential
+from keras.layers import Conv2D,MaxPooling2D,Dense,Flatten,Dropout
+

+
+
Dataset
Fetching the Data
!wget ftp://lhcftp.nlm.nih.gov/Open-Access-Datasets/Malaria/cell_images.zip
+!unzip cell_images.zip
+

+
+
Processing the Data
We resize all the images as 50x50 and add the numpy array of that image as well as their label names (Infected or Not) to common arrays.
data = []
+labels = []
+
+Parasitized = os.listdir("./cell_images/Parasitized/")
+for parasite in Parasitized:
+    try:
+        image=cv2.imread("./cell_images/Parasitized/"+parasite)
+        image_from_array = Image.fromarray(image, 'RGB')
+        size_image = image_from_array.resize((50, 50))
+        data.append(np.array(size_image))
+        labels.append(0)
+    except AttributeError:
+        print("")
+
+Uninfected = os.listdir("./cell_images/Uninfected/")
+for uninfect in Uninfected:
+    try:
+        image=cv2.imread("./cell_images/Uninfected/"+uninfect)
+        image_from_array = Image.fromarray(image, 'RGB')
+        size_image = image_from_array.resize((50, 50))
+        data.append(np.array(size_image))
+        labels.append(1)
+    except AttributeError:
+        print("")
+

+
+
Splitting Data
df = np.array(data)
+labels = np.array(labels)
+(X_train, X_test) = df[(int)(0.1*len(df)):],df[:(int)(0.1*len(df))]
+(y_train, y_test) = labels[(int)(0.1*len(labels)):],labels[:(int)(0.1*len(labels))]
+

+
+
s=np.arange(X_train.shape[0])
+np.random.shuffle(s)
+X_train=X_train[s]
+y_train=y_train[s]
+X_train = X_train/255.0
+

+
+
Model
Creating Model
By creating a sequential model, we create a linear stack of layers.
Note: The input shape for the first layer is 50,50 which corresponds with the sizes of the resized images
model = models.Sequential()
+model.add(layers.Conv2D(filters=16, kernel_size=2, padding='same', activation='relu', input_shape=(50,50,3)))
+model.add(layers.MaxPooling2D(pool_size=2))
+model.add(layers.Conv2D(filters=32,kernel_size=2,padding='same',activation='relu'))
+model.add(layers.MaxPooling2D(pool_size=2))
+model.add(layers.Conv2D(filters=64,kernel_size=2,padding="same",activation="relu"))
+model.add(layers.MaxPooling2D(pool_size=2))
+model.add(layers.Dropout(0.2))
+model.add(layers.Flatten())
+model.add(layers.Dense(500,activation="relu"))
+model.add(layers.Dropout(0.2))
+model.add(layers.Dense(2,activation="softmax"))#2 represent output layer neurons 
+model.summary()
+

+
+
Compiling Model
We use the adam optimiser as it is an adaptive learning rate optimization algorithm that's been designed specifically for training deep neural networks, which means it changes its learning rate automaticaly to get the best results
model.compile(optimizer="adam",
+              loss="sparse_categorical_crossentropy", 
+             metrics=["accuracy"])
+

+
+
Training Model
We train the model for 10 epochs on the training data and then validate it using the testing data
history = model.fit(X_train,y_train, epochs=10, validation_data=(X_test,y_test))
+

+
+
Train on 24803 samples, validate on 2755 samples

+
Compiling Model
We use the adam optimiser as it is an adaptive learning rate optimization algorithm that's been designed specifically for training deep neural networks, which means it changes its learning rate automaticaly to get the best results
model.compile(optimizer="adam",
+              loss="sparse_categorical_crossentropy", 
+             metrics=["accuracy"])
+

+
+
Training Model
We train the model for 10 epochs on the training data and then validate it using the testing data
history = model.fit(X_train,y_train, epochs=10, validation_data=(X_test,y_test))
+

+
+

+Making Predictions using Image Classifier (TensorFlow) | Navan Chauhan

Making Predictions using Image Classifier (TensorFlow)
This was tested on TF 2.x and works as of 2019-12-10
If you want to understand how to make your own custom image classifier, please refer to my previous post.
If you followed my last post, then you created a model which took an image of dimensions 50x50 as an input.
First we import the following if we have not imported these before
import cv2
+import os
+

+
+
Then we read the file using OpenCV.
image=cv2.imread(imagePath)
+

+
+
The cv2. imread() function returns a NumPy array representing the image. Therefore, we need to convert it before we can use it.
image_from_array = Image.fromarray(image, 'RGB')
+

+
+
Then we resize the image
size_image = image_from_array.resize((50,50))
+

+
+
After this we create a batch consisting of only one image
p = np.expand_dims(size_image, 0)
+

+
+
We then convert this uint8 datatype to a float32 datatype
img = tf.cast(p, tf.float32)
+

+
+
Finally we make the prediction
print(['Infected','Uninfected'][np.argmax(model.predict(img))])
+

+
+
Infected

+Polynomial Regression Using TensorFlow | Navan Chauhan
Navan Chauhan
16 minute readCreated on December 16, 2019Last modified on January 18, 2020
Polynomial Regression Using TensorFlow
In this tutorial you will learn about polynomial regression and how you can implement it in Tensorflow.
In this, we will be performing polynomial regression using 5 types of equations -
  • Linear
  • Quadratic
  • Cubic
  • Quartic
  • Quintic
Regression
What is Regression?
Regression is a statistical measurement that is used to try to determine the relationship between a dependent variable (often denoted by Y), and series of varying variables (called independent variables, often denoted by X ).
What is Polynomial Regression
This is a form of Regression Analysis where the relationship between Y and X is denoted as the nth degree/power of X. Polynomial regression even fits a non-linear relationship (e.g when the points don't form a straight line).
Imports
import tensorflow.compat.v1 as tf
+tf.disable_v2_behavior()
+import matplotlib.pyplot as plt
+import numpy as np
+import pandas as pd
+

+
+
Dataset
Creating Random Data
Even though in this tutorial we will use a Position Vs Salary datasset, it is important to know how to create synthetic data
To create 50 values spaced evenly between 0 and 50, we use NumPy's linspace funtion
linspace(lower_limit, upper_limit, no_of_observations)
x = np.linspace(0, 50, 50)
+y = np.linspace(0, 50, 50)
+

+
+
We use the following function to add noise to the data, so that our values
x += np.random.uniform(-4, 4, 50)
+y += np.random.uniform(-4, 4, 50)
+

+
+
Position vs Salary Dataset
We will be using https://drive.google.com/file/d/1tNL4jxZEfpaP4oflfSn6pIHJX7Pachm9/view (Salary vs Position Dataset)
!wget --no-check-certificate 'https://docs.google.com/uc?export=download&id=1tNL4jxZEfpaP4oflfSn6pIHJX7Pachm9' -O data.csv
+

+
+
df = pd.read_csv("data.csv")
+

+
+
df # this gives us a preview of the dataset we are working with
+

+
+
| Position          | Level | Salary  |
+|-------------------|-------|---------|
+| Business Analyst  | 1     | 45000   |
+| Junior Consultant | 2     | 50000   |
+| Senior Consultant | 3     | 60000   |
+| Manager           | 4     | 80000   |
+| Country Manager   | 5     | 110000  |
+| Region Manager    | 6     | 150000  |
+| Partner           | 7     | 200000  |
+| Senior Partner    | 8     | 300000  |
+| C-level           | 9     | 500000  |
+| CEO               | 10    | 1000000 |
+

+
+
We convert the salary column as the ordinate (y-cordinate) and level column as the abscissa
abscissa = df["Level"].to_list() # abscissa = [1,2,3,4,5,6,7,8,9,10]
+ordinate = df["Salary"].to_list() # ordinate = [45000,50000,60000,80000,110000,150000,200000,300000,500000,1000000]
+

+
+
n = len(abscissa) # no of observations
+plt.scatter(abscissa, ordinate)
+plt.ylabel('Salary')
+plt.xlabel('Position')
+plt.title("Salary vs Position")
+plt.show()
+

+
+
Defining Stuff
X = tf.placeholder("float")
+Y = tf.placeholder("float")
+

+
+
Defining Variables
We first define all the coefficients and constant as tensorflow variables haveing a random intitial value
a = tf.Variable(np.random.randn(), name = "a")
+b = tf.Variable(np.random.randn(), name = "b")
+c = tf.Variable(np.random.randn(), name = "c")
+d = tf.Variable(np.random.randn(), name = "d")
+e = tf.Variable(np.random.randn(), name = "e")
+f = tf.Variable(np.random.randn(), name = "f")
+

+
+
Model Configuration
learning_rate = 0.2
+no_of_epochs = 25000
+

+
+
Equations
deg1 = a*X + b
+deg2 = a*tf.pow(X,2) + b*X + c
+deg3 = a*tf.pow(X,3) + b*tf.pow(X,2) + c*X + d
+deg4 = a*tf.pow(X,4) + b*tf.pow(X,3) + c*tf.pow(X,2) + d*X + e
+deg5 = a*tf.pow(X,5) + b*tf.pow(X,4) + c*tf.pow(X,3) + d*tf.pow(X,2) + e*X + f
+

+
+
Cost Function
We use the Mean Squared Error Function
mse1 = tf.reduce_sum(tf.pow(deg1-Y,2))/(2*n)
+mse2 = tf.reduce_sum(tf.pow(deg2-Y,2))/(2*n)
+mse3 = tf.reduce_sum(tf.pow(deg3-Y,2))/(2*n)
+mse4 = tf.reduce_sum(tf.pow(deg4-Y,2))/(2*n)
+mse5 = tf.reduce_sum(tf.pow(deg5-Y,2))/(2*n)
+

+
+
Optimizer
We use the AdamOptimizer for the polynomial functions and GradientDescentOptimizer for the linear function
optimizer1 = tf.train.GradientDescentOptimizer(learning_rate).minimize(mse1)
+optimizer2 = tf.train.AdamOptimizer(learning_rate).minimize(mse2)
+optimizer3 = tf.train.AdamOptimizer(learning_rate).minimize(mse3)
+optimizer4 = tf.train.AdamOptimizer(learning_rate).minimize(mse4)
+optimizer5 = tf.train.AdamOptimizer(learning_rate).minimize(mse5)
+

+
+
init=tf.global_variables_initializer()
+

+
+
Model Predictions
For each type of equation first we make the model predict the values of the coefficient(s) and constant, once we get these values we use it to predict the Y values using the X values. We then plot it to compare the actual data and predicted line.

Results and Conclusion
You just learnt Polynomial Regression using TensorFlow!
Notes
Overfitting
> Overfitting refers to a model that models the training data too well.Overfitting happens when a model learns the detail and noise in the training data to the extent that it negatively impacts the performance of the model on new data. This means that the noise or random fluctuations in the training data is picked up and learned as concepts by the model. The problem is that these concepts do not apply to new data and negatively impact the models ability to generalize.
Source: Machine Learning Mastery
Basically if you train your machine learning model on a small dataset for a really large number of epochs, the model will learn all the deformities/noise in the data and will actually think that it is a normal part. Therefore when it will see some new data, it will discard that new data as noise and will impact the accuracy of the model in a negative manner

Polynomial Regression Using TensorFlow
In this tutorial you will learn about polynomial regression and how you can implement it in Tensorflow.
In this, we will be performing polynomial regression using 5 types of equations -
  • Linear
  • Quadratic
  • Cubic
  • Quartic
  • Quintic
Regression
What is Regression?
Regression is a statistical measurement that is used to try to determine the relationship between a dependent variable (often denoted by Y), and series of varying variables (called independent variables, often denoted by X ).
What is Polynomial Regression
This is a form of Regression Analysis where the relationship between Y and X is denoted as the nth degree/power of X. Polynomial regression even fits a non-linear relationship (e.g when the points don't form a straight line).
Imports
import tensorflow.compat.v1 as tf
+tf.disable_v2_behavior()
+import matplotlib.pyplot as plt
+import numpy as np
+import pandas as pd
+

+
+
Dataset
Creating Random Data
Even though in this tutorial we will use a Position Vs Salary datasset, it is important to know how to create synthetic data
To create 50 values spaced evenly between 0 and 50, we use NumPy's linspace funtion
linspace(lower_limit, upper_limit, no_of_observations)
x = np.linspace(0, 50, 50)
+y = np.linspace(0, 50, 50)
+

+
+
We use the following function to add noise to the data, so that our values
x += np.random.uniform(-4, 4, 50)
+y += np.random.uniform(-4, 4, 50)
+

+
+
Position vs Salary Dataset
We will be using https://drive.google.com/file/d/1tNL4jxZEfpaP4oflfSn6pIHJX7Pachm9/view (Salary vs Position Dataset)
!wget --no-check-certificate 'https://docs.google.com/uc?export=download&id=1tNL4jxZEfpaP4oflfSn6pIHJX7Pachm9' -O data.csv
+

+
+
df = pd.read_csv("data.csv")
+

+
+
df # this gives us a preview of the dataset we are working with
+

+
+
| Position          | Level | Salary  |
+|-------------------|-------|---------|
+| Business Analyst  | 1     | 45000   |
+| Junior Consultant | 2     | 50000   |
+| Senior Consultant | 3     | 60000   |
+| Manager           | 4     | 80000   |
+| Country Manager   | 5     | 110000  |
+| Region Manager    | 6     | 150000  |
+| Partner           | 7     | 200000  |
+| Senior Partner    | 8     | 300000  |
+| C-level           | 9     | 500000  |
+| CEO               | 10    | 1000000 |
+

+
+
We convert the salary column as the ordinate (y-cordinate) and level column as the abscissa
abscissa = df["Level"].to_list() # abscissa = [1,2,3,4,5,6,7,8,9,10]
+ordinate = df["Salary"].to_list() # ordinate = [45000,50000,60000,80000,110000,150000,200000,300000,500000,1000000]
+

+
+
n = len(abscissa) # no of observations
+plt.scatter(abscissa, ordinate)
+plt.ylabel('Salary')
+plt.xlabel('Position')
+plt.title("Salary vs Position")
+plt.show()
+

+
+
Defining Stuff
X = tf.placeholder("float")
+Y = tf.placeholder("float")
+

+
+
Defining Variables
We first define all the coefficients and constant as tensorflow variables haveing a random intitial value
a = tf.Variable(np.random.randn(), name = "a")
+b = tf.Variable(np.random.randn(), name = "b")
+c = tf.Variable(np.random.randn(), name = "c")
+d = tf.Variable(np.random.randn(), name = "d")
+e = tf.Variable(np.random.randn(), name = "e")
+f = tf.Variable(np.random.randn(), name = "f")
+

+
+
Model Configuration
learning_rate = 0.2
+no_of_epochs = 25000
+

+
+
Equations
deg1 = a*X + b
+deg2 = a*tf.pow(X,2) + b*X + c
+deg3 = a*tf.pow(X,3) + b*tf.pow(X,2) + c*X + d
+deg4 = a*tf.pow(X,4) + b*tf.pow(X,3) + c*tf.pow(X,2) + d*X + e
+deg5 = a*tf.pow(X,5) + b*tf.pow(X,4) + c*tf.pow(X,3) + d*tf.pow(X,2) + e*X + f
+

+
+
Cost Function
We use the Mean Squared Error Function
mse1 = tf.reduce_sum(tf.pow(deg1-Y,2))/(2*n)
+mse2 = tf.reduce_sum(tf.pow(deg2-Y,2))/(2*n)
+mse3 = tf.reduce_sum(tf.pow(deg3-Y,2))/(2*n)
+mse4 = tf.reduce_sum(tf.pow(deg4-Y,2))/(2*n)
+mse5 = tf.reduce_sum(tf.pow(deg5-Y,2))/(2*n)
+

+
+
Optimizer
We use the AdamOptimizer for the polynomial functions and GradientDescentOptimizer for the linear function
optimizer1 = tf.train.GradientDescentOptimizer(learning_rate).minimize(mse1)
+optimizer2 = tf.train.AdamOptimizer(learning_rate).minimize(mse2)
+optimizer3 = tf.train.AdamOptimizer(learning_rate).minimize(mse3)
+optimizer4 = tf.train.AdamOptimizer(learning_rate).minimize(mse4)
+optimizer5 = tf.train.AdamOptimizer(learning_rate).minimize(mse5)
+

+
+
init=tf.global_variables_initializer()
+

+
+
Model Predictions
For each type of equation first we make the model predict the values of the coefficient(s) and constant, once we get these values we use it to predict the Y values using the X values. We then plot it to compare the actual data and predicted line.

Results and Conclusion
You just learnt Polynomial Regression using TensorFlow!
Notes
Overfitting
> Overfitting refers to a model that models the training data too well.Overfitting happens when a model learns the detail and noise in the training data to the extent that it negatively impacts the performance of the model on new data. This means that the noise or random fluctuations in the training data is picked up and learned as concepts by the model. The problem is that these concepts do not apply to new data and negatively impact the models ability to generalize.
Source: Machine Learning Mastery
Basically if you train your machine learning model on a small dataset for a really large number of epochs, the model will learn all the deformities/noise in the data and will actually think that it is a normal part. Therefore when it will see some new data, it will discard that new data as noise and will impact the accuracy of the model in a negative manner

+Building a Fake News Detector with Turicreate | Navan Chauhan

Building a Fake News Detector with Turicreate
In this tutorial we will build a fake news detecting app from scratch, using Turicreate for the machine learning model and SwiftUI for building the app
Note: These commands are written as if you are running a jupyter notebook.
Building the Machine Learning Model
Data Gathering
To build a classifier, you need a lot of data. George McIntire (GH: @joolsa) has created a wonderful dataset containing the headline, body and wheter it is fake or real. Whenever you are looking for a dataset, always try searching on Kaggle and GitHub before you start building your own
Dependencies
I used a Google Colab instance for training my model. If you also plan on using Google Colab then I reccomend choosing a GPU Instance (It is Free) This allows you to train the model on the GPU. Turicreat is built on top of Apache's MXNet Framework, for us to use GPU we need to install a CUDA compatible MXNet package.
!pip install turicreate
+!pip uninstall -y mxnet
+!pip install mxnet-cu100==1.4.0.post0

Building the App using SwiftUI
Initial Setup
First we create a single view app (make sure you check the use SwiftUI button)
Then we copy our .mlmodel file to our project (Just drag and drop the file in the XCode Files Sidebar)
Our ML Model does not take a string directly as an input, rather it takes bag of words as an input. DescriptionThe bag-of-words model is a simplifying representation used in NLP, in this text is represented as a bag of words, without any regatd of grammar or order, but noting multiplicity
We define our bag of words function
func bow(text: String) -> [String: Double] {
+        var bagOfWords = [String: Double]()
+        
+        let tagger = NSLinguisticTagger(tagSchemes: [.tokenType], options: 0)
+        let range = NSRange(location: 0, length: text.utf16.count)
+        let options: NSLinguisticTagger.Options = [.omitPunctuation, .omitWhitespace]
+        tagger.string = text
+        
+        tagger.enumerateTags(in: range, unit: .word, scheme: .tokenType, options: options) { _, tokenRange, _ in
+            let word = (text as NSString).substring(with: tokenRange)
+            if bagOfWords[word] != nil {
+                bagOfWords[word]! += 1
+            } else {
+                bagOfWords[word] = 1
+            }
+        }
+        
+        return bagOfWords
+    }
+

+
+
We also declare our variables
@State private var title: String = ""
+@State private var headline: String = ""
+@State private var alertTitle = ""
+@State private var alertText = ""
+@State private var showingAlert = false
+

+
+
Finally, we implement a simple function which reads the two text fields, creates their bag of words representation and displays an alert with the appropriate result
Complete Code

+    @State private var title: String = ""

+Building a Fake News Detector with Turicreate | Navan Chauhan

Building a Fake News Detector with Turicreate
In this tutorial we will build a fake news detecting app from scratch, using Turicreate for the machine learning model and SwiftUI for building the app
Note: These commands are written as if you are running a jupyter notebook.
Building the Machine Learning Model
Data Gathering
To build a classifier, you need a lot of data. George McIntire (GH: @joolsa) has created a wonderful dataset containing the headline, body and wheter it is fake or real. Whenever you are looking for a dataset, always try searching on Kaggle and GitHub before you start building your own
Dependencies
I used a Google Colab instance for training my model. If you also plan on using Google Colab then I reccomend choosing a GPU Instance (It is Free) This allows you to train the model on the GPU. Turicreat is built on top of Apache's MXNet Framework, for us to use GPU we need to install a CUDA compatible MXNet package.
!pip install turicreate
+!pip uninstall -y mxnet
+!pip install mxnet-cu100==1.4.0.post0
+

+
+
If you do not wish to train on GPU or are running it on your computer, you can ignore the last two lines
Downloading the Dataset
!wget -q "https://github.com/joolsa/fake_real_news_dataset/raw/master/fake_or_real_news.csv.zip"
+!unzip fake_or_real_news.csv.zip
+

+
+
Model Creation
import turicreate as tc
+tc.config.set_num_gpus(-1) # If you do not wish to use GPUs, set it to 0
+

+
+
dataSFrame = tc.SFrame('fake_or_real_news.csv')
+

+
+
The dataset contains a column named "X1", which is of no use to us. Therefore, we simply drop it
dataSFrame.remove_column('X1')
+

+
+
Splitting Dataset
train, test = dataSFrame.random_split(.9)
+

+
+
Training
model = tc.text_classifier.create(
+    dataset=train,
+    target='label',
+    features=['title','text']

Converting between image and NumPy array
import numpy
+import PIL
+
+# Convert PIL Image to NumPy array
+img = PIL.Image.open("foo.jpg")
+arr = numpy.array(img)
+
+# Convert array to Image
+img = PIL.Image.fromarray(arr)
+

+
+
Saving an Image
try:
+    img.save(destination, "JPEG", quality=80, optimize=True, progressive=True)
+except IOError:
+    PIL.ImageFile.MAXBLOCK = img.size[0] * img.size[1]
+    img.save(destination, "JPEG", quality=80, optimize=True, progressive=True)

The image files are not actually JPEG, thus we first need to save them in the correct format for Turicreate
from PIL import Image
+import glob
+
+
+folders = ["default","smoke","fire"]
+for folder in folders:
+  n = 1
+  for file in glob.glob("./data/data/img_data/train/" + folder + "/*.jpg"):
+    im = Image.open(file)
+    rgb_im = im.convert('RGB')
+    rgb_im.save((folder + "/" + str(n) + ".jpg"), quality=100)
+    n +=1 
+  for file in glob.glob("./data/data/img_data/train/" + folder + "/*.jpg"):
+    im = Image.open(file)
+    rgb_im = im.convert('RGB')
+    rgb_im.save((folder + "/" + str(n) + ".jpg"), quality=100)
+    n +=1
+

+
+

!mkdir train
+!mv default ./train
+!mv smoke ./train
+!mv fire ./train
+

!pip install turicreate

The image files are not actually JPEG, thus we first need to save them in the correct format for Turicreate
from PIL import Image
+import glob
+
+
+folders = ["default","smoke","fire"]
+for folder in folders:
+  n = 1
+  for file in glob.glob("./data/data/img_data/train/" + folder + "/*.jpg"):
+    im = Image.open(file)
+    rgb_im = im.convert('RGB')
+    rgb_im.save((folder + "/" + str(n) + ".jpg"), quality=100)
+    n +=1 
+  for file in glob.glob("./data/data/img_data/train/" + folder + "/*.jpg"):
+    im = Image.open(file)
+    rgb_im = im.convert('RGB')
+    rgb_im.save((folder + "/" + str(n) + ".jpg"), quality=100)
+    n +=1
+

+
+

!mkdir train
+!mv default ./train
+!mv smoke ./train
+!mv fire ./train
+

Making the Image Classifier
Making an SFrame
!pip install turicreate

+data["label"] = data["path"].apply(lambda path: os.path.basename(os.path.dirname(path)))
