On the estimation bias in double q-learning
Did you know?
WebDouble-Q-learning tackles this issue by utilizing two estimators, yet re-sults in an under-estimation bias. Similar to over-estimation in Q-learning, in certain scenar-ios, the under-estimation bias may degrade per-formance. In this work, we introduce a new bias-reduced algorithm called Ensemble Boot-strapped Q-Learning (EBQL), a natural extension WebIt is known that the estimation bias hinges heavily on the ensemble size (i.e., the number of Q-function approximators used in the target), and that determining the ‘right’ ensemble size is highly nontrivial, because of the time-varying nature of the function approximation errors during the learning process.
