Research Type Experimental Empirical results show the effectiveness of our method on both linear bandits and general CB. Specifically, BRE outperforms previous methods like Bayes Gap and Lin Gap E on LB. We evaluate the performance of BRE by comparing with various baselines. Following (Xu, Honda, and Sugiyama 2018), we design experiments on synthetic data and a real-data simulated Explore-K problem. We test BRE on LB and some other general CB problems.
