웹2024년 4월 6일 · Lessons on applying bandits in industry. First, UCB and Thompson Sampling outperform ε-greedy. By default, ε-greedy is unguided and chooses actions uniformly at random. In contrast, UCB and Thompson Sampling are guided by confidence bounds and probability distributions that shrink as the action is tried more often. 웹2024년 11월 11일 · Neural Contextual Bandits with UCB-based Exploration.
