Three‐Way Data Analysis With Explainable Tucker3 Clustering (XT3Clus)

Applied Stochastic Models in Business and Industry, Volume 42, Issue 1, January/February 2026.
ABSTRACT In an era of increasingly complex data, three‐way arrays capturing information across units, variables and occasions are ubiquitous in fields from chemometrics to finance. However, extracting meaningful and interpretable patterns from such data remain a significant challenge.

Randomly sparsified Richardson iteration: A dimension‐independent sparse linear solver

Communications on Pure and Applied Mathematics, Volume 79, Issue 1, Page 89-122, January 2026.
Abstract Recently, a class of algorithms combining classical fixed‐point iterations with repeated random sparsification of approximate solution vectors has been successfully applied to eigenproblems with matrices as large as 10108×10108$10^{108} \times 10^{108}$. So far, a complete mathematical explanation for this success has proven elusive.

Sophisticated Audio Source Separation: A Statistical Exploration of Clarity and Precision With FastICA

Engineering Reports, Volume 8, Issue 1, January 2026.
This workflow presents a complete pipeline for audio data processing, beginning with format conversion, channel adjustments, and cleaning, followed by enhancement and visualization techniques. It further applies signal separation using FastICA, postprocessing, and evaluation metrics (SDR, SIR, SAR) to improve audio analysis and support future research ...
