WebApr 25, 2024 · The way we resolve this in Q-learning is by introducing the epsilon greedy algorithm: with the probability of epsilon, our agent chooses a random action (and explores) but exploits the... Webϵ -Greedy Exploration is an exploration strategy in reinforcement learning that takes an exploratory action with probability ϵ and a greedy action with probability 1 − ϵ. It tackles the exploration-exploitation tradeoff with reinforcement learning algorithms: the desire to explore the state space with the desire to seek an optimal policy.

WebThe Epsilon Greedy Strategy is a simple method to balance exploration and exploitation. The epsilon stands for the probability of choosing to explore and exploits when there are smaller chances of exploring. At the start, the epsilon rate is higher, meaning the agent is in exploration mode.
