Reinforcement Learning Models

Definition and Overview

Reinforcement learning (RL) is a branch of machine learning that focuses on training intelligent agents to make decisions in dynamic environments. Unlike supervised learning, RL does not rely on labeled input-output pairs. Instead, it uses a reward system to guide the agent's actions. The goal is to maximize cumulative rewards over time.

In RL, the environment is often modeled as a Markov Decision Process (MDP). This framework helps the agent decide its next action based on the current state and potential outcomes. RL algorithms are categorized into two main types:

• Model-based RL: The agent builds an internal model of the environment to predict outcomes.

• Model-free RL: The agent learns through trial and error without creating a model.

Early computational models, such as the Rescorla-Wagner model, laid the foundation for RL by mathematically explaining learning processes. Today, RL plays a vital role in advancing artificial intelligence by enabling agents to learn autonomously through exploration and exploitation.

Examples of Reinforcement Learning Models

Reinforcement learning has led to groundbreaking achievements in AI. Some notable examples include:
