An International Consortium for Evaluations of Societal-Scale Risks from Advanced AI

no code implementations22 Oct 2023 Ross Gruetzemacher, Alan Chan, Kevin Frazier, Christy Manning, Štěpán Los, James Fox, José Hernández-Orallo, John Burden, Matija Franklin, Clíodhna Ní Ghuidhir, Mark Bailey, Daniel Eth, Toby Pilditch, Kyle Kilian

Given rapid progress toward advanced AI and risks from frontier AI systems (advanced AI systems pushing the boundaries of the AI capabilities frontier), the creation and implementation of AI governance and regulatory schemes deserves prioritization and substantial investment.

On Imperfect Recall in Multi-Agent Influence Diagrams

no code implementations11 Jul 2023 James Fox, Matt MacDermott, Lewis Hammond, Paul Harrenstein, Alessandro Abate, Michael Wooldridge

Multi-agent influence diagrams (MAIDs) are a popular game-theoretic model based on Bayesian networks.

Reasoning about Causality in Games

no code implementations5 Jan 2023 Lewis Hammond, James Fox, Tom Everitt, Ryan Carey, Alessandro Abate, Michael Wooldridge

Regarding question iii), 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.

Learning Task Automata for Reinforcement Learning using Hidden Markov Models

no code implementations25 Aug 2022 Alessandro Abate, Yousif Almulla, James Fox, David Hyland, Michael Wooldridge

Second, we propose a novel method for distilling the task automaton (assumed to be a deterministic finite automaton) from the learnt product MDP.

Concentric Spherical GNN for 3D Representation Learning

no code implementations18 Mar 2021 James Fox, Bo Zhao, Sivasankaran Rajamanickam, Rampi Ramprasad, Le Song

Learning 3D representations that generalize well to arbitrarily oriented inputs is a challenge of practical importance in applications varying from computer vision to physics and chemistry.

Equilibrium Refinements for Multi-Agent Influence Diagrams: Theory and Practice

1 code implementation9 Feb 2021 Lewis Hammond, James Fox, Tom Everitt, Alessandro Abate, Michael Wooldridge

Multi-agent influence diagrams (MAIDs) are a popular form of graphical model that, for certain classes of games, have been shown to offer key complexity and explainability advantages over traditional extensive form game (EFG) representations.

How Robust Are Graph Neural Networks to Structural Noise?

no code implementations21 Dec 2019 James Fox, Sivasankaran Rajamanickam

Graph neural networks (GNNs) are an emerging model for learning graph embeddings and making predictions on graph structured data.

Exploring AI Futures Through Role Play

no code implementations19 Dec 2019 Shahar Avin, Ross Gruetzemacher, James Fox

We present an innovative methodology for studying and teaching the impacts of AI through a role play game.
