Jordan algebras, hemiplex numbers, and the Cholesky decomposition of arbitrary symmetric matrices
Alan Edelman, Timothy E. Holy
Positive-semidefinite matrices are most efficiently factored using the Cholesky decomposition. For indefinite matrices, the Cholesky factorization does not exist, and the alternati…

GSVD-NMF: Recovering Missing Features in Non-negative Matrix Factorization
Youdong Guo, Timothy E. Holy
Non-negative matrix factorization (NMF) is an important tool in signal processing and widely used to separate mixed sources into their components. Algorithms for NMF require that t…
