Webb4 nov. 2024 · While using shaped rewards can be beneficial when solving sparse reward tasks, their successful application often requires careful engineering and is problem specific. For instance, in tasks where the agent must achieve some goal state, simple distance-to-goal reward shaping often fails, as it renders learning vulnerable to local …
WebbReward shaping (Mataric, 1994; Ng et al., 1999) is a technique to modify the reward signal, and, for instance, can be used to relabel and learn from failed rollouts, based on which ones made more progress towards task completion. rcg healthWebbThe second is shaped rewards which are designed specifically to make the task easier to learn by introducing biases in the learning process. The inductive bias which shaped rewards introduce is problematic for emergent language experimentation because it biases the object of study: the emergent language.
