Thompson Sampling, otherwise known as Bayesian Bandits, is the Bayesian approach to the multi-armed bandits problem. The basic idea is to treat the average reward 𝛍 from each bandit as a random variable and use the data we have collected so far to calculate its distribution. Then, at each step, we will sample a point …
