The Unity Machine Learning Agents Toolkit (ML-Agents) is an open-source Unity3D plugin that enables games and simulations to serve as environments for training intelligent agents. Agents - usually implemented as scripted C# Unity components - can be trained using reinforcement learning, imitation learning, neuroevolution, or other machine learning methods through a Python API.

(Unity ML-agent) If I change the reward for an action, would it be better to do training all over again?
For example, let's asume that Reward for an action was a negative reward, and Agent was very very well trained to avoid that action.
In this situation, if I change the reward for that action to a positive reward and continue with the previous…
