๐ค AI Summary
This work proposes a novel approach, WIAE-GPF, that explicitly embeds uncertainty throughout the generative modeling pipeline for financial time series forecastingโa domain where overconfident models often yield high-risk mispredictions during market shocks. By integrating gated reparameterization with similarity- and confidence-based routing mechanisms, the method dynamically modulates representation learning and prediction generation. Furthermore, it incorporates uncertainty-driven regularization and calibration strategies to enhance reliability. Evaluated on the NYISO dataset, the model achieves a 63.5% reduction in mean squared error (MSE), improving from 0.3508 to 0.1281, and demonstrates markedly enhanced robustness during shock periods, with mSE decreasing from 0.2739 to 0.1748. These results indicate a significant mitigation of misprediction risk under extreme market events.
๐ Abstract
Financial time-series forecasting is a high-stakes problem where regime shifts and shocks make point-accurate yet overconfident models dangerous. We propose Uncertainty-Gated Generative Modeling (UGGM), which treats uncertainty as an internal control signal that gates (i) representation via gated reparameterization, (ii) propagation via similarity and confidence routing, and (iii) generation via uncertainty-controlled predictive distributions, together with uncertainty-driven regularization and calibration to curb miscalibration. Instantiated on Weak Innovation AutoEncoder (WIAE-GPF), our UG-WIAE-GPF significantly improves risk-sensitive forecasting, delivering a 63.5\% MSE reduction on NYISO (0.3508 $\rightarrow$ 0.1281), with improved robustness under shock intervals (mSE: 0.2739 $\rightarrow$ 0.1748).
