credit assignment
The machine learning problem of determining which actions contributed to an outcome.
Credit assignment is the problem of determining which of many actions or computations contributed to the success or failure of a final outcome. It is especially important in reinforcement learning, where rewards arrive only after a sequence of actions, and it also refers to deciding how much each weight in a neural network is responsible for an error.
