Webb: The agent will get a +1 reward for each combat unit produced. This is a more challenging task because the agent needs to learn 1) harvest resources when 2) produce barracks, 3) produce combat units once enough resources are gathered, 4) move produced combat units out of the way so as to not block the production of new combat units. Webb29 maj 2024 · An example reward function using distance could be one where the reward decreases as 1/(1+d) where d defines the distance from where the agent currently is relative to a goal location. Conclusion:
Webbof observations, and can therefore provide well-shaped reward functions for RL. By learning to reach random goals sampled from the latent variable model, the goal-conditioned policy learns about the world and can be used to achieve new, user-specified goals at test-time.
