After messing around with some Q-Learning stuff during the summer, and developing the qlearner.js library, I've wanted to make some pre-existing game learn. Recently it dawned on me that I could extract the 'This webpage is not available' page on Google Chrome, which includes a hidden T-Rex running / jumping game, that you simply start / play by pressing on the spacebar, and make the little T-Rex (whom I've nicknamed Dino) to learn how to avoid the cakti (plural for cactus).
It was a lot of fun doing it actually. And although it's far from perfect, and the qlearner.js library probably isn't the best library to use in this sitation,it still works!!Addmitedly, it takes a really really really long time to make much progress.
Head over to the Github Page to see the demo
