It is the easiest option for cross-browser augmented reality.</p><p>The same code works for iOS, Android, Desktops and even VR Browsers!</p><p>It was initially created by Jerome Etienne and is now maintained by Nicolo Carpignoli and the AR-js Organisation</p><h2>NFT</h2><p>Usually for augmented reality you need specialised markers, like this Hiro marker (notice the thick non-aesthetic borders 🤢)</p><img src="https://upload.wikimedia.org/wikipedia/commons/4/48/Hiro_marker_ARjs.png"/><p>This is called marker based tracking where the code knows what to look for. NFT or Natural Feature Tracing converts normal images into markers by extracting 'features' from it, this way you can use any image of your liking!</p><p>I'll be using my GitHub profile picture</p><img src="https://navanchauhan.github.io//images/me.jpeg"/><h2>Creating the Marker!</h2><p>First we need to create the marker files required by AR.js for NFT.

Because I can.</p><h2>Installing makedepend</h2><p><code>makedepend</code> is a Unix tool used to generate dependencies of C source files. Most modern programs do not use this anymore, but then again AutoDock Vina's source code hasn't been changed since 2011. The first hurdle came when I saw that there was no makedepend command, neither was there any package on any development repository for iOS. So, I tracked down the original source code for <code>makedepend</code> (https://github.com/DerellLicht/makedepend). According to the repository this is actually the source code for the makedepend utility that came with some XWindows distribution back around Y2K. I am pretty sure there is a problem with my current compiler configuration because I had to manually edit the <code>Makefile</code> to provide the path to the iOS SDKs using the <code>-isysroot</code> flag.</p><h2>Editing the Makefile</h2><p>Original Makefile ( I used the provided mac Makefile base )</p><pre><code><div class="highlight"><span></span><span class="nv">BASE</span><span class="o">=</span>/usr/local -<span class="nv">BOOST_VERSION</span><span class="o">=</span>1_41 -<span class="nv">BOOST_INCLUDE</span> <span class="o">=</span> <span class="k">$(</span>BASE<span class="k">)</span>/include -<span class="nv">C_PLATFORM</span><span class="o">=</span>-arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min<span class="o">=</span><span class="m">10</span>.4 -<span class="nv">GPP</span><span class="o">=</span>/usr/bin/g++ -<span class="nv">C_OPTIONS</span><span class="o">=</span> -O3 -DNDEBUG -<span class="nv">BOOST_LIB_VERSION</span><span class="o">=</span> - -include ../../makefile_common -</div></code></pre><p>I installed Boost 1.68.0-1 from Sam Bingner's repository.

To give a little background, I had tried to compile AutoDock Vina using a cross-compiler but I had miserably failed.</p><p>I am running the Checkr1n jailbreak on my iPad and the Unc0ver jailbreak on my phone.</p><h2>But Why?</h2><p>Well, just because I can. This is literally the only reason I tried compiling it and also partially because in the long run I want to compile AutoDock Vina so I can do Molecular Docking on the go.</p><h2>Let's Go!</h2><p>How hard can it be to compile open babel right? It is just a simple software with clear and concise build instructions. I just need to use <code>cmake</code> to build and the <code>make</code> to install.</p><p>It is 11 AM in the morning. I install <code>clang, cmake and make</code> from the Sam Bingner's repository, fired up ssh, downloaded the source code and ran the build command.`clang</p><h3>Fail No. 1</h3><p>I couldn't even get cmake to run, I did a little digging around StackOverflow and founf that I needed the iOS SDK, sure no problem.

Of course this changed as the genre become mature</p><h1>How to Vaporwave</h1><p>The first track which is considered to be actual Vaporwave is Ramona Xavier's Macintosh Plus, this set the the guidelines for making Vaporwave</p><ul><li>Take a 1980s RnB song</li><li>Slow it down</li><li>Add Bass and Treble</li><li>Add again</li><li>Add Reverb ( make sure its wet )</li></ul><p>There you have your very own Vaporwave track.</p><p>( Now, there are some tracks being produced which are not remixes and are original )</p><h1>My Remix</h1><iframe width="300" height="202"

George McIntire (GH: @joolsa) has created a wonderful dataset containing the headline, body and whether it is fake or real.

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."</span><span class="p">]}</span> -<span class="n">example_prediction</span> <span class="o">=</span> <span class="n">model</span><span class="o">.</span><span class="n">classify</span><span class="p">(</span><span class="n">tc</span><span class="o">.</span><span class="n">SFrame</span><span class="p">(</span><span class="n">example_text</span><span class="p">))</span> -<span class="nb">print</span><span class="p">(</span><span class="n">example_prediction</span><span class="p">,</span> <span class="n">flush</span><span class="o">=</span><span class="kc">True</span><span class="p">)</span> -</div></code></pre><pre><code><div class="highlight"><span></span><span class="o">+-------+--------------------+</span> -<span class="o">|</span> <span class="k">class</span> <span class="err">| </span><span class="nc">probability</span> <span class="o">|</span> -<span class="o">+-------+--------------------+</span> -<span class="o">|</span> <span class="n">FAKE</span> <span class="o">|</span> <span class="mf">0.9245648658345308</span> <span class="o">|</span> -<span class="o">+-------+--------------------+</span> -<span class="p">[</span><span class="mi">1</span> <span class="n">rows</span> <span class="n">x</span> <span class="mi">2</span> <span class="n">columns</span><span class="p">]</span> -</div></code></pre><h3>Exporting the Model</h3><pre><code><div class="highlight"><span></span><span class="n">model_name</span> <span class="o">=</span> <span class="s1">'FakeNews'</span> -<span class="n">coreml_model_name</span> <span class="o">=</span> <span class="n">model_name</span> <span class="o">+</span> <span class="s1">'.mlmodel'</span> -<span class="n">exportedModel</span> <span class="o">=</span> <span class="n">model</span><span class="o">.</span><span class="n">export_coreml</span><span class="p">(</span><span class="n">coreml_model_name</span><span class="p">)</span> -</div></code></pre><p><strong>Note: To download files from Google Colab, simply click on the files section in the sidebar, right click on filename and then click on download</strong></p><p><a href="https://colab.research.google.com/drive/1onMXGkhA__X2aOFdsoVL-6HQBsWQhOP4">Link to Colab Notebook</a></p><h2>Building the App using SwiftUI</h2><h3>Initial Setup</h3><p>First we create a single view app (make sure you check the use SwiftUI button)</p><p>Then we copy our .mlmodel file to our project (Just drag and drop the file in the XCode Files Sidebar)</p><p>Our ML Model does not take a string directly as an input, rather it takes bag of words as an input.

Polynomial regression even fits a non-linear relationship (e.g when the points don't form a straight line).</p><h2>Imports</h2><pre><code><div class="highlight"><span></span><span

TensorFlow!</p><h2>Notes</h2><h3>Overfitting</h3><blockquote><p>> 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 generalise.</p></blockquote><blockquote><p>Source: Machine Learning Mastery</p></blockquote><p>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</p>]]></content:encoded></item><item><guid isPermaLink="true">https://navanchauhan.github.io/posts/2019-12-10-TensorFlow-Model-Prediction</guid><title>Making Predictions using Image Classifier (TensorFlow)</title><description>Making predictions for image classification models built using TensorFlow</description><link>https://navanchauhan.github.io/posts/2019-12-10-TensorFlow-Model-Prediction</link><pubDate>Tue, 10 Dec 2019 11:10:00 +0530</pubDate><content:encoded><![CDATA[<h1>Making Predictions using Image Classifier (TensorFlow)</h1><p><em>This was tested on TF 2.x and works as of 2019-12-10</em></p><p>If you want to understand how to make your own custom image classifier, please refer to my previous post.</p><p>If you followed my last post, then you created a model which took an image of dimensions 50x50 as an input.</p><p>First we import the following if we have not imported these before</p><pre><code><div class="highlight"><span></span><span class="kn">import</span> <span class="nn">cv2</span> -<span class="kn">import</span> <span class="nn">os</span> -</div></code></pre><p>Then we read the file using OpenCV.</p><pre><code><div class="highlight"><span></span><span class="n">image</span><span class="o">=</span><span class="n">cv2</span><span class="o">.</span><span class="n">imread</span><span class="p">(</span><span class="n">imagePath</span><span class="p">)</span> -</div></code></pre><p>The cv2. imread() function returns a NumPy array representing the image.

-### Building the DEB - -**For building the deb you need a `*nix` system, otherwise you can build it using your iPhones** - -##### Pre-Requisite for MacOS users -1) Install Homenbrew `/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"` (Run this in the terminal) -2) Install dpkg, by running `brew install dpkg` - -**There is a terrible thing called .DS_Store which if not removed, will cause a problem during either build or installation** - -* To remove this we first need to open the folder in the terminal - -* Launch the Terminal and then drag-and-drop the 'themeNameForCydia' folder on the Terminal icon in the dock -* Now, run `find . -name "*.DS_Store" -type f -delete` - -##### Pre-Requisite for Windows Users -* SSH into your iPhone and drag and drop the `themeNameForCyia` folder on the terminal - -##### Common Instructions - -* You should be at the root of the folder in the terminal, i.e Inside `themeNameForCydia` -* running `ls` should show the following output - -``` -DEBIAN Library -``` - -* Now, in the terminal enter the following `cd .. && dpkg -b themeNameForCydia ` - -**Now you will have the `themeNameForCydia.deb` in the same directory** - -You can share this with your friends :+1: -</p></div><span>Tagged with: </span><ul class="tag-list"><li><a href="/tags/tutorial">Tutorial</a></li><li><a href="/tags/jailbreak">Jailbreak</a></li><li><a href="/tags/designing">Designing</a></li><li><a href="/tags/snowboard">Snowboard</a></li><li><a href="/tags/anemone">Anemone</a></li></ul></article></div><footer><p>Made with ❤️ using <a href="https://github.com/johnsundell/publish">Publish</a></p><p><a href="/feed.rss">RSS feed</a></p></footer></body></html>

Conclusion</h2><p>You just learnt Polynomial Regression using TensorFlow!</p><h2>Notes</h2><h3>Overfitting</h3><blockquote><p>> 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 generalise.</p></blockquote><blockquote><p>Source: Machine Learning Mastery</p></blockquote><p>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</p></div><span>Tagged with: </span><ul class="tag-list"><li><a href="/tags/tutorial">Tutorial</a></li><li><a href="/tags/tensorflow">Tensorflow</a></li><li><a href="/tags/colab">Colab</a></li></ul></article></div><footer><p>Made with ❤️ using <a href="https://github.com/johnsundell/publish">Publish</a></p><p><a href="/feed.rss">RSS feed</a></p></footer></body></html>

George McIntire (GH: @joolsa) has created a wonderful dataset containing the headline, body and whether it is fake or real.

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."</span><span class="p">]}</span> -<span class="n">example_prediction</span> <span class="o">=</span> <span class="n">model</span><span class="o">.</span><span class="n">classify</span><span class="p">(</span><span class="n">tc</span><span class="o">.</span><span class="n">SFrame</span><span class="p">(</span><span class="n">example_text</span><span class="p">))</span> -<span class="nb">print</span><span class="p">(</span><span class="n">example_prediction</span><span class="p">,</span> <span class="n">flush</span><span class="o">=</span><span class="kc">True</span><span class="p">)</span> -</div></code></pre><pre><code><div class="highlight"><span></span><span class="o">+-------+--------------------+</span> -<span class="o">|</span> <span class="k">class</span> <span class="err">| </span><span class="nc">probability</span> <span class="o">|</span> -<span class="o">+-------+--------------------+</span> -<span class="o">|</span> <span class="n">FAKE</span> <span class="o">|</span> <span class="mf">0.9245648658345308</span> <span class="o">|</span> -<span class="o">+-------+--------------------+</span> -<span class="p">[</span><span class="mi">1</span> <span class="n">rows</span> <span class="n">x</span> <span class="mi">2</span> <span class="n">columns</span><span class="p">]</span> -</div></code></pre><h3>Exporting the Model</h3><pre><code><div class="highlight"><span></span><span class="n">model_name</span> <span class="o">=</span> <span class="s1">'FakeNews'</span> -<span class="n">coreml_model_name</span> <span class="o">=</span> <span class="n">model_name</span> <span class="o">+</span> <span class="s1">'.mlmodel'</span> -<span class="n">exportedModel</span> <span class="o">=</span> <span class="n">model</span><span class="o">.</span><span class="n">export_coreml</span><span class="p">(</span><span class="n">coreml_model_name</span><span class="p">)</span> -</div></code></pre><p><strong>Note: To download files from Google Colab, simply click on the files section in the sidebar, right click on filename and then click on download</strong></p><p><a href="https://colab.research.google.com/drive/1onMXGkhA__X2aOFdsoVL-6HQBsWQhOP4">Link to Colab Notebook</a></p><h2>Building the App using SwiftUI</h2><h3>Initial Setup</h3><p>First we create a single view app (make sure you check the use SwiftUI button)</p><p>Then we copy our .mlmodel file to our project (Just drag and drop the file in the XCode Files Sidebar)</p><p>Our ML Model does not take a string directly as an input, rather it takes bag of words as an input.

To give a little background, I had tried to compile AutoDock Vina using a cross-compiler but I had miserably failed.</p><p>I am running the Checkr1n jailbreak on my iPad and the Unc0ver jailbreak on my phone.</p><h2>But Why?</h2><p>Well, just because I can. This is literally the only reason I tried compiling it and also partially because in the long run I want to compile AutoDock Vina so I can do Molecular Docking on the go.</p><h2>Let's Go!</h2><p>How hard can it be to compile open babel right? It is just a simple software with clear and concise build instructions. I just need to use <code>cmake</code> to build and the <code>make</code> to install.</p><p>It is 11 AM in the morning. I install <code>clang, cmake and make</code> from the Sam Bingner's repository, fired up ssh, downloaded the source code and ran the build command.`clang</p><h3>Fail No. 1</h3><p>I couldn't even get cmake to run, I did a little digging around StackOverflow and founf that I needed the iOS SDK, sure no problem.

Because I can.</p><h2>Installing makedepend</h2><p><code>makedepend</code> is a Unix tool used to generate dependencies of C source files. Most modern programs do not use this anymore, but then again AutoDock Vina's source code hasn't been changed since 2011. The first hurdle came when I saw that there was no makedepend command, neither was there any package on any development repository for iOS. So, I tracked down the original source code for <code>makedepend</code> (https://github.com/DerellLicht/makedepend). According to the repository this is actually the source code for the makedepend utility that came with some XWindows distribution back around Y2K. I am pretty sure there is a problem with my current compiler configuration because I had to manually edit the <code>Makefile</code> to provide the path to the iOS SDKs using the <code>-isysroot</code> flag.</p><h2>Editing the Makefile</h2><p>Original Makefile ( I used the provided mac Makefile base )</p><pre><code><div class="highlight"><span></span><span class="nv">BASE</span><span class="o">=</span>/usr/local -<span class="nv">BOOST_VERSION</span><span class="o">=</span>1_41 -<span class="nv">BOOST_INCLUDE</span> <span class="o">=</span> <span class="k">$(</span>BASE<span class="k">)</span>/include -<span class="nv">C_PLATFORM</span><span class="o">=</span>-arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min<span class="o">=</span><span class="m">10</span>.4 -<span class="nv">GPP</span><span class="o">=</span>/usr/bin/g++ -<span class="nv">C_OPTIONS</span><span class="o">=</span> -O3 -DNDEBUG -<span class="nv">BOOST_LIB_VERSION</span><span class="o">=</span> - -include ../../makefile_common -</div></code></pre><p>I installed Boost 1.68.0-1 from Sam Bingner's repository.
