Modeling Dynamic Mixtures of Time-Delay Systems from Streaming Time Series

Researchers present DelayMix, an online machine learning framework that models streaming time series as dynamic mixtures of time-delay systems, enabling rapid adaptation to regime shifts while maintaining memory efficiency. The method uses tensor decomposition to capture system dynamics and input delays, demonstrating superior forecasting accuracy on non-stationary data compared to existing approaches.
