Random Matrix Theory (RMT) has emerged as an indispensable framework for understanding the statistical properties of matrices whose entries are determined by probabilistic processes. Initially ...
Nonnegative Matrix Factorization (NMF) has emerged as a powerful tool in data analysis, particularly noted for its ability to produce parts‐based, interpretable representations from high-dimensional ...
In this paper a solution is given for the recurrence equation $\mathbf{\mathit{U}}_{\mathbf{\mathit{n}}}=\mathbf{\mathit{T}}\{\mathbf{\mathit{U}}_{\mathbf{\mathit{n ...
Abstract: A new algebraic approach to approximation of correlation matrices of discrete signals based on a special family of square matrices with sparse circulant alternation of elements is developed.
