Learning not to Regret

no code implementations2 Mar 2023 David Sychrovsky, Michal Sustr, Elnaz Davoodi, Marc Lanctot, Martin Schmid

To scale to games that cannot fit in memory, we can use search with value functions.

Over-communicate no more: Situated RL agents learn concise communication protocols

no code implementations2 Nov 2022 Aleksandra Kalinowska, Elnaz Davoodi, Florian Strub, Kory W Mathewson, Ivana Kajic, Michael Bowling, Todd D Murphey, Patrick M Pilarski

While it is known that communication facilitates cooperation in multi-agent settings, it is unclear how to design artificial agents that can learn to effectively and efficiently communicate with each other.

Reassessing Evaluation Practices in Visual Question Answering: A Case Study on Out-of-Distribution Generalization

no code implementations24 May 2022 Aishwarya Agrawal, Ivana Kajić, Emanuele Bugliarello, Elnaz Davoodi, Anita Gergely, Phil Blunsom, Aida Nematzadeh

Vision-and-language (V&L) models pretrained on large-scale multimodal data have demonstrated strong performance on various tasks such as image captioning and visual question answering (VQA).

The Frost Hollow Experiments: Pavlovian Signalling as a Path to Coordination and Communication Between Agents

no code implementations17 Mar 2022 Patrick M. Pilarski, Andrew Butcher, Elnaz Davoodi, Michael Bradley Johanson, Dylan J. A. Brenneis, Adam S. R. Parker, Leslie Acker, Matthew M. Botvinick, Joseph Modayil, Adam White

Our results showcase the speed of learning for Pavlovian signalling, the impact that different temporal representations do (and do not) have on agent-agent coordination, and how temporal aliasing impacts agent-agent and human-agent interactions differently.

Pavlovian Signalling with General Value Functions in Agent-Agent Temporal Decision Making

no code implementations11 Jan 2022 Andrew Butcher, Michael Bradley Johanson, Elnaz Davoodi, Dylan J. A. Brenneis, Leslie Acker, Adam S. R. Parker, Adam White, Joseph Modayil, Patrick M. Pilarski

We further show how to computationally build this adaptive signalling process out of a fixed signalling process, characterized by fast continual prediction learning and minimal constraints on the nature of the agent receiving signals.

Solving Common-Payoff Games with Approximate Policy Iteration

2 code implementations11 Jan 2021 Samuel Sokota, Edward Lockhart, Finbarr Timbers, Elnaz Davoodi, Ryan D'Orazio, Neil Burch, Martin Schmid, Michael Bowling, Marc Lanctot

While this choice precludes CAPI from scaling to games as large as Hanabi, empirical results demonstrate that, on the games to which CAPI does scale, it is capable of discovering optimal joint policies even when other modern multi-agent reinforcement learning algorithms are unable to do so.

The E2E NLG Challenge: A Tale of Two Systems

no code implementations WS 2018 Charese Smiley, Elnaz Davoodi, Dezhao Song, Frank Schilder

This paper presents the two systems we entered into the 2017 E2E NLG Challenge: TemplGen, a templated-based system and SeqGen, a neural network-based system.
