Topic: Reinforcement Learning

• Three types of AI
  • Supervised Learning
  • Unsupervised Learning
  • Reinforcement Learning
• Online vs Offline RL
• Optimization algorithms
  • Value optimization
    • SARSA
    • Q-Learning
  • Policy optimization
    • Policy Gradients
    • Actor-Critic
    • Proximal Policy Optimization
• Value vs Policy Optimization
  • Value optimization is more intuitive (Value loss)
  • Policy optimization is less intuitive at first (policy gradients)
  • Converting values to policies in deep learning is difficult
• Imitation Learning
  • Supervised policy learning
  • Often used to bootstrap reinforcement learning
• Policy Evaluation
  • Propensity scoring versus model-based
• Challenges to training RL model
  • Two optimization loops
    • Collecting feedback vs updating the model
  • Difficult optimization target
    • Policy evaluation
• RLHF &  GRPO
