ICA Lens: Interpreting Language Models Without Training Another Dictionary

Researchers introduce ICALens, a new method for interpreting language model representations using independent component analysis (ICA) instead of expensive sparse autoencoders (SAEs). The approach efficiently recovers interpretable directions without requiring large neural dictionary training, achieving competitive performance on standard benchmarks while offering a faster, more accessible alternative for LLM analysis.

Reservoir Subspace Injection for Online ICA under Top-n Whitening

Researchers developed Reservoir Subspace Injection (RSI) to improve online Independent Component Analysis under nonlinear mixing conditions. The study identifies performance bottlenecks in top-n whitening and proposes a guarded RSI controller that preserves system performance while achieving 1.7 dB improvement over vanilla online ICA methods.

A 1/R Law for Kurtosis Contrast in Balanced Mixtures

Researchers prove a mathematical law showing that kurtosis-based Independent Component Analysis (ICA) becomes less effective in wide, balanced mixtures due to contrast decay following a 1/R relationship. The study demonstrates that purification techniques can restore contrast performance and provides theoretical bounds for practical implementation.
