Interpretable Machine Learning for Survival Analysis
Biometrical Journal, Volume 67, Issue 6, December 2025.ABSTRACT With the spread and rapid advancement of black box machine learning (ML) models, the field of interpretable machine learning (IML) or explainable artificial intelligence (XAI) has become increasingly important over the last decade. This is particularly relevant for survival analysis, where the adoption of IML techniques promotes transparency ...

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011 We describe the method of technical analysis of highly volatile markets in the framework of signal processing theory, which uses Chebyshev filter. Berg method is used to estimate spectral density of the signal power.

Non-uniform cosine modulated filter banks using meta-heuristic algorithms in CSD space
Journal of Advanced Research, 2015 This paper presents an efficient design of non-uniform cosine modulated filter banks (CMFB) using canonic signed digit (CSD) coefficients. CMFB has got an easy and efficient design approach. Non-uniform decomposition can be easily obtained by merging the

Launch Uncertainty Analysis Under Barrel Erosion Using Experiments and Random Matrix Theory
International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 762-774, December 2025.ABSTRACT The effects of barrel erosion on artillery firing performance have long been a subject of concern, but its effect on launch uncertainty has yet to be investigated. This article explores the influence of barrel erosion on the interior ballistic mechanical properties and launch disturbances.

Multichannel Sampling of Pulse Streams at the Rate of Innovation
, 2010 We consider minimal-rate sampling schemes for infinite streams of delayed and weighted versions of a known pulse shape. The minimal sampling rate for these parametric signals is referred to as the rate of innovation and is equal to the number of degrees ...
