Agent-Specific Effects: A Causal Effect Propagation Analysis in Multi-Agent MDPs

no code implementations17 Oct 2023 Stelios Triantafyllou, Aleksa Sukovic, Debmalya Mandal, Goran Radanovic

These challenges are particularly prominent in the context of multi-agent sequential decision-making, where the causal effect of an agent's action on the outcome depends on how other agents respond to that action.

Performative Reinforcement Learning

no code implementations30 Jun 2022 Debmalya Mandal, Stelios Triantafyllou, Goran Radanovic

We introduce the framework of performative reinforcement learning where the policy chosen by the learner affects the underlying reward and transition dynamics of the environment.

Actual Causality and Responsibility Attribution in Decentralized Partially Observable Markov Decision Processes

no code implementations1 Apr 2022 Stelios Triantafyllou, Adish Singla, Goran Radanovic

Responsibility attribution is complementary and aims to identify the extent to which decision makers (agents) are responsible for this outcome.

On Blame Attribution for Accountable Multi-Agent Sequential Decision Making

no code implementations NeurIPS 2021 Stelios Triantafyllou, Adish Singla, Goran Radanovic

We formalize desirable properties of blame attribution in the setting of interest, and we analyze the relationship between these properties and the studied blame attribution methods.
