The question of how to determine which states and actions are responsible for a certain outcome is known as the credit assignment problem remains central research in reinforcement learning artificial intelligence. Eligibility traces enable efficient recent sequence experienced by agent, but not counterfactual sequences that could also have led current state. In this work, we introduce expected ...

We introduce and study the main properties of a class convex risk measures that refine Expected Shortfall by simultaneously controlling expected losses associated with different portions tail distribution. The corresponding adjusted Shortfalls quantify as minimum amount capital has to be raised injected into financial position X ensure ES p ( ) does not exceed pre-specified threshold g for ever...
