MÁQUINA vs. HOMEM: Quem vence no JOGO do DINO?

TL;DR

AI learns to play Dino game, challenging human skills.

Transcript

Today we are going to use artificial intelligence to train a machine to play the Dinosaur game on Google Chrome and see if it does better than a human being. We've hacked the game a few times here at Manual do Mundo. First I tried to do it with Arduino. The Arduino would hit the computer key and try to jump. Then I switched, I made the Arduino pr...
