How does the concept of exploration and exploitation trade-off manifest in bandit problems, and what are some of the common strategies used to address this trade-off?
The exploration-exploitation trade-off is a fundamental concept in the domain of reinforcement learning, particularly in the context of bandit problems. Bandit problems, which are a subset of reinforcement learning problems, involve a scenario where an agent must choose between multiple options (or "arms"), each with an uncertain reward. The primary challenge is to balance the
Explain the concept of regret in reinforcement learning and how it is used to evaluate the performance of an algorithm.
In the domain of reinforcement learning (RL), the concept of "regret" is integral to understanding and evaluating the performance of algorithms, particularly in the context of the tradeoff between exploration and exploitation. Regret quantifies the difference in performance between an optimal strategy and the strategy employed by the learning algorithm. This metric helps in assessing
