New research challenges neural network representation comparison metrics

A new research paper explores the limitations of standard metrics used to compare neural network representations, particularly when these networks operate in superposition. The study demonstrates that common alignment metrics can be misleading because they depend on the encoding of features rather than the features themselves. This can lead to networks with identical feature content appearing dissimilar. The research proposes that by using techniques like sparse autoencoders, which are designed to handle compressed sensing, the true similarity of latent features can be recovered, even in systems with more features than neurons.
