Geometric structures and deviations on James’ symmetric positive-definite matrix bicone domain
Geometric structures and deviations on James’ symmetric positive-definite matrix bicone domain arXiv:2603.02483v1 Announce Type: new Abstract: Symmetric positive-definite (SPD) matrix datasets play a central role across numerous scientific disciplines, including signal processing, statistics, finance, computer vision, information theory, and machine learning among others. The set of SPD matrices forms a cone which can be viewed…

Recurrent Neural Networks with Linear Structures for Electricity Price Forecasting
Recurrent Neural Networks with Linear Structures for Electricity Price Forecasting arXiv:2512.04690v1 Announce Type: new Abstract: We present a novel recurrent neural network architecture designed explicitly for day-ahead electricity price forecasting, aimed at improving short-term decision-making and operational management in energy systems. Our combined forecasting model embeds linear structures, such as expert models and Kalman filters,…
