Visual Encoders for Data-Efficient Imitation Learning in Modern Video Games

no code implementations4 Dec 2023 Lukas Schäfer, Logan Jones, Anssi Kanervisto, Yuhan Cao, Tabish Rashid, Raluca Georgescu, Dave Bignell, Siddhartha Sen, Andrea Treviño Gavito, Sam Devlin

Video games have served as useful benchmarks for the decision making community, but going beyond Atari games towards training agents in modern games has been prohibitively expensive for the vast majority of the research community.

Navigates Like Me: Understanding How People Evaluate Human-Like AI in Video Games

no code implementations2 Mar 2023 Stephanie Milani, Arthur Juliani, Ida Momennejad, Raluca Georgescu, Jaroslaw Rzpecki, Alison Shaw, Gavin Costello, Fei Fang, Sam Devlin, Katja Hofmann

We aim to understand how people assess human likeness in navigation produced by people and artificially intelligent (AI) agents in a video game.

Go-Explore Complex 3D Game Environments for Automated Reachability Testing

no code implementations1 Sep 2022 Cong Lu, Raluca Georgescu, Johan Verwey

Modern AAA video games feature huge game levels and maps which are increasingly hard for level testers to cover exhaustively.

Navigation Turing Test (NTT): Learning to Evaluate Human-Like Navigation

1 code implementation20 May 2021 Sam Devlin, Raluca Georgescu, Ida Momennejad, Jaroslaw Rzepecki, Evelyn Zuniga, Gavin Costello, Guy Leroy, Ali Shaw, Katja Hofmann

A key challenge on the path to developing agents that learn complex human-like behavior is the need to quickly and accurately quantify human-likeness.
