DQN wins at Breakout
Hello there
Say hello to Garfield
Garfield Gridworld and the need for DQN
But we don’t have a labelled dataset here…
What is a Replay Memory?
What do Q-values represent: Intuition
What do Q-values represent: Formalisation
Wait, Q-values are recursive
NN estimates Q-value
We finally have labels…
Erm, but the targets are estimates… (Bootstrapping)
DQN Paper: 2013 vs 2015 (Introducing the Target Network)
Updated loss function
Don’t forget to explore during training
Let’s summarise this information overload
Don’t forget to check out the blog posts
Seeeeee ya
