Improved Replicable Boosting with Majority-of-Majorities

Kasper Green Larsen, Markus Engelund Mathiasen, Clement Svendsen

Abstract: We introduce a new replicable boosting algorithm which significantly improves the sample complexity compared to previous algorithms. The algorithm works by doing two layers of majority voting, using an improved version of the replicable boosting algorithm introduced by Impagliazzo et al. [2022] in the bottom layer.
