  • CNN, Artistic style
  • Reinforcement learning, game play

Reinforcement Learning

https://en.wikipedia.org/wiki/Bellman_equation Planning vs Learning Planning

  • Know about Model
  • Dynamic Programming

Learning

  • Model free
  • Monte Carlo method, Temporal Difference learning

Monte-Carlo Reinforcement Learning

  • 직접적인 경험으로부터 배움
  • Model-free : 직접적인 MDP transition과 보상을 알 필요가 없다
  • 끝난 에피소드로부터 학습한다.
  • episodic MDP 문제만 풀 수 있다.


Temporal-Difference Learning

  • 경험으로부터 학습한다
  • model-free
  • 끌나지 않은 경험에서도 학습 가능하다(Bootstraping)
