[P] Machine Learning: Doodle Recognition with Convolutional Neural Network

Hi all,

I’m launching a step-by-step video tutorial series on making a game like “Quick, Draw!”. As you probably know, it is an online game that challenges players to draw a doodle and then artificial intelligence guesses what the drawings represent. So I thought this group would appreciate this project.

Using Phaser 2 framework and Tensorflow.js library, I’ve created a complete HTML5 game called Doodle Predictor that runs directly in the browser and recognizes doodles.

To classify drawings, the game uses Machine Learning with a Convolutional Neural Network. The model is trained on a small subset of the Quick Draw Dataset.

I tried to make this project easy enough for someone without any machine learning experience to follow. So if you are interested in it, here are the links:
