Webmulti-armed bandit problem. The above technique then gives a bound of order O p lnjAjT on the expected regret, which contradicts the known 1 p jAjT lower bound. It remains for … In probability theory and machine learning, the multi-armed bandit problem (sometimes called the K- or N-armed bandit problem ) is a problem in which a fixed limited set of resources must be allocated between competing (alternative) choices in a way that maximizes their expected gain, when each … Meer weergeven The multi-armed bandit problem models an agent that simultaneously attempts to acquire new knowledge (called "exploration") and optimize their decisions based on existing knowledge (called "exploitation"). … Meer weergeven A major breakthrough was the construction of optimal population selection strategies, or policies (that possess uniformly maximum convergence rate to the population with highest mean) in the work described below. Optimal … Meer weergeven Another variant of the multi-armed bandit problem is called the adversarial bandit, first introduced by Auer and Cesa-Bianchi (1998). In this variant, at each iteration, an agent chooses an arm and an adversary simultaneously chooses the payoff structure for … Meer weergeven This framework refers to the multi-armed bandit problem in a non-stationary setting (i.e., in presence of concept drift). In the non-stationary setting, it is assumed that the expected reward for an arm $${\displaystyle k}$$ can change at every time step Meer weergeven A common formulation is the Binary multi-armed bandit or Bernoulli multi-armed bandit, which issues a reward of one with probability $${\displaystyle p}$$, and otherwise a … Meer weergeven A useful generalization of the multi-armed bandit is the contextual multi-armed bandit. At each iteration an agent still has to choose between arms, but they also see a d-dimensional feature vector, the context vector they can use together with the rewards … Meer weergeven In the original specification and in the above variants, the bandit problem is specified with a discrete and finite number of arms, often indicated by the variable $${\displaystyle K}$$.
