Automatically Interpreting Millions of Features in Large Language Models

Gonçalo Paulo, Alex Mallen, Caden Juang +1

While the activations of neurons in deep neural networks usually do not have a simple human-understandable interpretation, sparse autoencoders (SAEs) can be used to transform these…

Neural Networks Learn Statistics of Increasing Complexity

Nora Belrose, Quintin Pope, Lucia Quirke +2

The distributional simplicity bias (DSB) posits that neural networks learn low-order moments of the data distribution first, before moving on to higher-order correlations. In this…

Koopman-theoretic Approach for Identification of Exogenous Anomalies in Nonstationary Time-series Data

Alex Mallen, Christoph A. Keller, J. Nathan Kutz

In many scenarios, it is necessary to monitor a complex system via a time-series of observations and determine when anomalous exogenous events have occurred so that relevant action…
