Researchers use sparse autoencoders to interpret EEG foundation models

Researchers have developed a method using Sparse Autoencoders (SAEs) to interpret the internal workings of EEG foundation models. This technique extracts and analyzes features from model embeddings, linking them to clinical data like age and sex. The framework reveals representational failures such as 'wrecking-ball' interventions that degrade performance and confounding clinical factors that cannot be disentangled, offering insights into how these models process physiological data.
