Red Teaming Language Models with Language Models

no code implementations7 Feb 2022 Ethan Perez, Saffron Huang, Francis Song, Trevor Cai, Roman Ring, John Aslanides, Amelia Glaese, Nat McAleese, Geoffrey Irving

In this work, we automatically find cases where a target LM behaves in a harmful way, by generating test cases ("red teaming") using another LM.

Acme: A Research Framework for Distributed Reinforcement Learning

3 code implementations1 Jun 2020 Matt Hoffman, Bobak Shahriari, John Aslanides, Gabriel Barth-Maron, Feryal Behbahani, Tamara Norman, Abbas Abdolmaleki, Albin Cassirer, Fan Yang, Kate Baumli, Sarah Henderson, Alex Novikov, Sergio Gómez Colmenarejo, Serkan Cabi, Caglar Gulcehre, Tom Le Paine, Andrew Cowie, Ziyu Wang, Bilal Piot, Nando de Freitas

Ultimately, we show that the design decisions behind Acme lead to agents that can be scaled both up and down and that, for the most part, greater levels of parallelization result in agents with equivalent performance, just faster.

When to use parametric models in reinforcement learning?

2 code implementations NeurIPS 2019 Hado van Hasselt, Matteo Hessel, John Aslanides

We examine the question of when and how parametric models are most useful in reinforcement learning.

Universal Reinforcement Learning Algorithms: Survey and Experiments

1 code implementation30 May 2017 John Aslanides, Jan Leike, Marcus Hutter

Many state-of-the-art reinforcement learning (RL) algorithms typically assume that the environment is an ergodic Markov Decision Process (MDP).


AIXIjs: A Software Demo for General Reinforcement Learning

1 code implementation22 May 2017 John Aslanides

The universal Bayesian agent AIXI (Hutter, 2005) is a model of a maximally intelligent agent, and plays a central role in the sub-field of general reinforcement learning (GRL).

Generalised Discount Functions applied to a Monte-Carlo AImu Implementation

1 code implementation3 Mar 2017 Sean Lamont, John Aslanides, Jan Leike, Marcus Hutter

We have added to the GRL simulation platform AIXIjs the functionality to assign an agent arbitrary discount functions, and an environment which can be used to determine the effect of discounting on an agent's policy.
