Multi-armed bandits — Introduction to Reinforcement Learning

Web29 mai 2024 · In this post, we’ll build on the Multi-Armed Bandit problem by relaxing the assumption that the reward distributions are stationary. Non-stationary reward distributions change over time, and thus our algorithms have to adapt to them. There’s simple way to solve this: adding buffers. Let us try to do it to an ϵ -greedy policy and Thompson Sampling. Web21 dec. 2024 · The K-armed bandit (also known as the Multi-Armed Bandit problem) is a simple, yet powerful example of allocation of a limited set of resources over time and under uncertainty. It has been initially studied by Thompson (1933), who suggested a heuristic for navigating the exploration-exploitation dilemma. pitch imdb https://ajliebel.com

Uses the standard approximation for confidence interval of a proportion (mean + c * sqrt (mean * (1-mean) / n)). This is similar to the ‘TreeHeuristic’ in the reference paper, but uses UCB as a MAB policy instead of Thompson sampling.

Web3 iul. 2024 · Regret is a quantity to analyse how well you performed on the bandit instance in hindsight. While calculating the regret, you know the value of $μ_*$ because you know the true values of all $μ_k$. You calculate regret just to gauge how your algorithm did.
