Google Deepmind DQN plays Atari Pacman

Показать описание
Google Deepminds deep learning algorithm DQN learns to play Atari Pacman. You can clearly see progress, although learning time was not that long. The algorithm knew nothing about the controls. It was fed with raw pixel data and had to decide on the next action. It had no idea of the princible of a wall or a ghost. It's only goal was to maximize the score.

If deep mind can't even beat Pacman after a day of playing I feel better about myself.

The problem with this game is
That the a.i can't compare 2 different states,
It does not know that it just made progress by collencting one of these white dots, it only sees which movements are ideal in most cases in a similar situation.

You would need an a.i that is rewarded while playing not only at the end for a highscore.

Also finding a connection between the screen having more black/ that correlating with a higher score/ and how it achieves the screens blackness seem incomprehensible for this type of A.i

Why Pacman doesn't eat the ghosts?

Wouldn't it make sense to punish the fitness when he dies?
