UnverifiedThe multi-armed bandit problem is the most simplified model of the exploration-exploitation dilemma, and strategies such as ε-greedy, UCB, and Thompson Sampling are each different solutions to that dilemma.68% similarUnverifiedThompson Sampling is a multi-armed bandit algorithm used in Bayesian methods to accelerate marketing decisions.63% similarUnverifiedClassic multi-armed bandit algorithms (such as ε-greedy) assume that the reward distribution of each arm is independent; when the action space explodes combinatorially and feedback is sparse, the exploration cost of independently evaluating each arm grows linearly with the number of actions, and efficiency drops sharply.62% similarUnverifiedUCB is the core algorithm for the classic bandit problem: it constructs a confidence upper bound for each action's reward estimate and selects the action with the largest upper bound, corresponding to O(√T) regret.62% similarVerifiedJailbreak techniques can be categorized into prompt injection, adversarial prefix attacks, multi-step context construction, and automated jailbreaking.60% similar
