Towards Automated Circuit Discovery for Mechanistic Interpretability

2 code implementations NeurIPS 2023 Arthur Conmy, Augustine N. Mavor-Parker, Aengus Lynch, Stefan Heimersheim, Adrià Garriga-Alonso

For example, the ACDC algorithm rediscovered 5/5 of the component types in a circuit in GPT-2 Small that computes the Greater-Than operation.

A Simple Approach for State-Action Abstraction using a Learned MDP Homomorphism

no code implementations14 Sep 2022 Augustine N. Mavor-Parker, Matthew J. Sargent, Andrea Banino, Lewis D. Griffin, Caswell Barry

Consequently, impressive improvements in sample efficiency have been achieved when a suitable MDP homomorphism can be constructed a priori -- usually by exploiting a practioner's knowledge of environment symmetries.

Escaping Stochastic Traps with Aleatoric Mapping Agents

1 code implementation8 Feb 2021 Augustine N. Mavor-Parker, Kimberly A. Young, Caswell Barry, Lewis D. Griffin

Exploration in environments with sparse rewards is difficult for artificial agents.

Scattering Networks on the Sphere for Scalable and Rotationally Equivariant Spherical CNNs

no code implementations ICLR 2022 Jason D. McEwen, Christopher G. R. Wallis, Augustine N. Mavor-Parker

Convolutional neural networks (CNNs) constructed natively on the sphere have been developed recently and shown to be highly effective for the analysis of spherical data.

Efficient Generalized Spherical CNNs

1 code implementation ICLR 2021 Oliver J. Cobb, Christopher G. R. Wallis, Augustine N. Mavor-Parker, Augustin Marignier, Matthew A. Price, Mayeul d'Avezac, Jason D. McEwen

We develop two new strictly equivariant layers with reduced complexity $\mathcal{O}(CL^4)$ and $\mathcal{O}(CL^3 \log L)$, making larger, more expressive models computationally feasible.
