Backward Coherence and Hidden-State Stability in Recurrent Neural Networks: A Quasi-Reverse-Martingale Theory
Researchers have developed a new theoretical framework called backward coherence to analyze hidden-state stability in recurrent neural networks (RNNs). This approach treats the hidden-state sequence as a quasi-reverse-martingale, enabling more stable and interpretable representations. Simulations and real-world data studies demonstrate that this method can significantly improve stability, reduce tracking errors, and enhance forecasting accuracy, particularly under concept drift.
