A feature engineering algorithm reducing the number of features while retaining the basis information necessary to reconstruct the original data. A matrix V is factorized into (usually) two matrices W ...

Nakajima and Grojnowski have shown that the cohomology H of Hilb(X) is naturally a representation of the Heisenberg Lie algebra modelled on the cohomology of X, and is isomorphic as a representation ...

Abstract: In his doctoral dissertation in 1797, Gauss proved the fundamental theorem of algebra, which states that any one-dimensional (1-D) polynomial of degree n with complex coefficients can be ...

A comprehensive Python library implementing state-of-the-art integer factorization algorithms, from simple trial division to the General Number Field Sieve.

ABSTRACT: Hyperspectral unmixing is a powerful tool for the remote sensing image mining. Nonnegative matrix factorization (NMF) has been adopted to deal with this issue, while the precision of ...
