New Coded Hankel Polynomial Chaos method for spectral mode identification
Researchers have developed a novel spectral formulation called Coded Hankel Polynomial Chaos (CH-PC) for identifying dominant polynomial-chaos modes. This method transforms polynomial-chaos coefficients into a generatin…

New methods for high-dimensional change-point detection unveiled on arXiv
Two new research papers, submitted to arXiv in August 2026, introduce novel methods for detecting changes in high-dimensional data. The first paper focuses on nonparametric change-point detection using low-rank degree-t…

Mean Squared Error: Its mathematical origins and role in optimization
The article delves into the mathematical origins and application of Mean Squared Error (MSE), a fundamental concept in modeling and statistics. It explains why squaring errors is crucial for creating a smooth, convex lo…

New counterexamples challenge KKT stationarity in mirror descent
Researchers have demonstrated that sequences generated by bounded mirror descent, using a Legendre kernel and specific step sizes, do not always converge to a Karush--Kuhn--Tucker (KKT) stationary point. This finding ch…
