DeRegiME: Deep Regime Mixtures for Probabilistic Forecasting under Distribution Shift
Researchers have developed DeRegiME, a novel probabilistic forecasting method designed to handle distribution shifts in time series data. This approach uses a deep mixture of experts model with a sparse variational Gaussian process to separate latent uncertainty regimes from the underlying signal. DeRegiME offers an interpretable decomposition of mean, residual, and noise, effectively identifying changepoints and improving forecasting accuracy. AI
