Reinforcement Learning Fundamentals Quiz

Study Notes

Focus of Reinforcement Learning

Reinforcement learning centers on training agents to make sequential decisions by maximizing cumulative rewards.
It emphasizes learning optimal actions through trial and error interactions with the environment.

Differences from Supervised Learning

Unlike supervised learning, which utilizes labeled datasets to guide learning, reinforcement learning learns through feedback based on actions taken.
Supervised learning focuses on output predictions for given inputs, while reinforcement learning targets behavior that leads to the best long-term strategies.

Environment Representation

The environment in reinforcement learning is typically represented as a Markov Decision Process (MDP), encompassing states, actions, rewards, and transitions.
This formalization allows agents to navigate through different situations and optimize their decision-making process.

Reinforcement Learning vs. Classical Dynamic Programming

Reinforcement learning algorithms adapt dynamically to uncertainty in the environment while classical dynamic programming assumes a predetermined model of the environment.
RL emphasizes exploration of the environment to discover effective strategies, as opposed to explicitly solving a model.

Balance in Reinforcement Learning

Reinforcement learning focuses on achieving a balance between exploration (trying new actions) and exploitation (making the best-known choice).
This balance is crucial to ensure robust learning and prevent premature convergence on suboptimal policies.
