Inversion-Free Natural Gradient Descent on Riemannian Manifolds
Dario Draca, Takuo Matsubara, Minh-Ngoc Tran
The natural gradient method is a central tool for statistical optimisation, but its broader application is hindered by the assumption of a Euclidean parameter space, the repeated e…
From Noise to Laws: Regularized Time-Series Forecasting via Denoised Dynamic Graphs
Hongwei Ma, Junbin Gao, Minh-ngoc Tran
Long-horizon multivariate time-series forecasting is challenging because realistic predictions must (i) denoise heterogeneous signals, (ii) track time-varying cross-series dependen…
Signals, Concepts, and Laws: Toward Universal, Explainable Time-Series Forecasting
Hongwei Ma, Junbin Gao, Minh-Ngoc Tran
Accurate, explainable and physically credible forecasting remains a persistent challenge for multivariate time-series whose statistical properties vary across domains. We propose D…
PREIG: Physics-informed and Reinforcement-driven Interpretable GRU for Commodity Demand Forecasting
Hongwei Ma, Junbin Gao, Minh-Ngoc Tran
Accurately forecasting commodity demand remains a critical challenge due to volatile market dynamics, nonlinear dependencies, and the need for economically consistent predictions.…
