Recommender systems trained in a continuous learning fashion are plagued by the feedback loop problem, also known as algorithmic bias.

Why so gloomy? A Bayesian explanation of human pessimism bias in the multi-armed bandit task

no code implementations NeurIPS 2018 Dalin Guo, Angela J. Yu

We find that the "pessimism bias" in the bandit task is well captured by the prior mean of DBM when fitted to human choices; but it is poorly captured by the prior mean of the Fixed Belief Model (FBM), an alternative Bayesian model that (correctly) assumes reward rates to be constants.
