ISS2: An Extension of Iterative Source Steering Algorithm for Majorization-Minimization-Based Independent Vector Analysis

Rintaro Ikeshita, Tomohiro Nakatani

A majorization-minimization (MM) algorithm for independent vector analysis optimizes a separation matrix $W = [w_{1}, \dots, w_{m}]^{h} \in C^{m \times m}$ by minimizing a surr…

Block Coordinate Descent Algorithms for Auxiliary-Function-Based Independent Vector Extraction

Rintaro Ikeshita, Tomohiro Nakatani, Shoko Araki

In this paper, we address the problem of extracting all super-Gaussian source signals from a linear mixture in which (i) the number of super-Gaussian sources $K$ is less than that…
