WebFeb 24, 2024 · In this article we will explore three different methods for selecting our output token, these are: > Greedy Decoding > Random Sampling > Beam Search. It’s pretty important to understand how each of these works — often-times in language applications, the solution to a poor output can be a simple switch between these four methods. WebApr 10, 2024 · As an off-policy algorithm, Q-learning evaluates and updates a policy that differs from the policy used to take action. Specifically, Q-learning uses an epsilon-greedy policy, where the agent selects the action with the highest Q-value with probability 1-epsilon and selects a random action with probability epsilon.
