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.
