Webrithm. We then propose two online greedy learning algorithms with semi-bandit feedbacks, which use multi-armed bandit and pure exploration bandit policies at each level of greedy learning, one for each of the regret metrics respectively. Both algorithms achieve O(logT) problem-dependent regret bound (Tbeing the time WebDec 18, 2024 · Epsilon-Greedy is a simple method to balance exploration and exploitation by choosing between exploration and exploitation randomly. The epsilon-greedy, where epsilon refers to the probability of choosing to explore, exploits most of the time with a small chance of exploring. Pseudocode for the Epsilon Greedy bandit algorithm
Webε-greedy is the classic bandit algorithm. At every trial, it randomly chooses an action with probability ε and greedily chooses the highest value action with probability 1 - ε.
