WebSep 30, 2024 · Bandit algorithms or samplers, are a means of testing and optimising variant allocation quickly. In this post I’ll provide an introduction to Thompson sampling (TS) and its properties. I’ll also compare Thompson sampling against the epsilon-greedy algorithm, which is another popular choice for MAB problems. Everything will be …
WebJan 4, 2024 · The Greedy algorithm is the simplest heuristic in sequential decision problem that carelessly takes the locally optimal choice at each round, disregarding any advantages of exploring and/or information gathering.
