• Abstract: Causal games are probabilistic graphical models that enable causal queries to be answered in multi-agent settings. They extend causal Bayesian networks by specifying decision and utility variables to represent the agents' degrees of freedom and objectives. In multi-agent settings, whether each agent decides on their policy before or after knowing the causal intervention is important as this affects whether they can respond to the intervention by adapting their policy. Consequently, previous work in causal games imposed chronological constraints on permissible interventions. We relax this by outlining a sound and complete set of primitive causal interventions so the effect of any arbitrarily complex interventional query can be studied in multi-agent settings. We also demonstrate applications to the design of safe AI systems by considering causal mechanism design and commitment.

• Causal Influence in Federated Edge Inference [34.487472866247586]
  In this paper, we consider a setting where heterogeneous agents with connectivity are performing inference using unlabeled streaming data. In order to overcome the uncertainty, agents cooperate with each other by exchanging their local inferences with and through a fusion center. Various scenarios reflecting different agent participation patterns and fusion center policies are investigated.

  Causal modelling can aid autonomous agents in making decisions and explaining outcomes. Here we identify challenges relating to causality in the context of a drone system operating in a salt mine. We propose a probabilistic causal framework consisting of: causally-informed POMDP planning, online SCM adaptation, and post-hoc counterfactual explanations.

  Multi-agent influence diagrams (MAIDs) are a popular game-theoretic model based on Bayesian networks. We show how to solve MAIDs with forgetful and absent-minded agents using mixed policies and two types of correlated equilibrium. We also describe applications of MAIDs to Markov games and team situations, where imperfect recall is often unavoidable.

  We study causal representation learning, the task of inferring latent causal variables and their causal relations from mixtures of the variables. Our goal is to identify both the ground truth latents and their causal graph up to a set of ambiguities which we show to be irresolvable from interventional data.

• Reasoning about Causality in Games [63.930126666879396]
  Causal reasoning and game-theoretic reasoning are fundamental topics in artificial intelligence. We introduce mechanised games, which encode dependencies between agents' decision rules and the distributions governing the game. We describe correspondences between causal games and other formalisms, and explain how causal games can be used to answer queries that other causal or game-theoretic models do not support.

  We introduce the concept of bounded rationality from an information-theoretic view into the game-theoretic framework. This allows the robots to reason other agents' sub-optimal behaviors and act accordingly under their computational constraints. We demonstrate that the resulting framework allows the robots to reason about different levels of rational behaviors of other agents and compute a reasonable strategy under its computational constraint.
