WebNov 11, 2024 · The -armed bandit problem is a simplified reinforcement learning setting. There is only one state; we (the agent) sit in front of k slot machines. There are actions: pulling one of the distinct arms. The reward values of the actions are immediately available after taking an action: -armed bandit is a simple and powerful representation. WebJun 14, 2016 · The simplest reinforcement learning problem is the n-armed bandit. Essentially, there are n-many slot machines, each with a different fixed payout probability. The goal is to discover the machine with the best payout, and maximize the returned reward by always choosing it. We are going to make it even simpler, by only having two possible …

WebInverse reinforcement learning (IRL) is a promising approach for understanding such behavior, as it aims to infer the unknown reward function of an agent from its observed trajectories through state space. However, IRL has yet to be widely applied in neuroscience. One potential reason for this is that existing IRL frameworks assume that an ...

We illustrate these points by discussing multi-armed bandit problems, a special case of RL problems. The multi-armed bandit is a model for a set of slot machines.
