Momentum LMS Algorithm Theory Advanced for Nonstationary Data

Researchers have developed a new theoretical framework for the Momentum Least Mean Squares (MLMS) algorithm, designed to handle nonstationary data streams common in large-scale processing. The paper derives tracking performance and regret bounds for MLMS in time-varying stochastic linear systems, addressing the complexities introduced by momentum in stability analysis. Experimental results on both synthetic and real-world data confirm MLMS's ability to adapt rapidly and track effectively in nonstationary environments, suggesting its utility for modern online learning applications.
