Boolean Matrix Factorization via Nonnegative Auxiliary Optimization
Duc P. Truong, Erik Skau, Derek Desantis +1
A novel approach to Boolean matrix factorization (BMF) is presented. Instead of solving the BMF problem directly, this approach solves a nonnegative optimization problem with the c…
Factorization of Binary Matrices: Rank Relations, Uniqueness and Model Selection of Boolean Decomposition
Derek DeSantis, Erik Skau, Duc P. Truong +1
The application of binary matrices are numerous. Representing a matrix as a mixture of a small collection of latent vectors via low-rank decomposition is often seen as an advantage…
Coarse-Grain Cluster Analysis of Tensors with Application to Climate Biome Identification
Derek DeSantis, Phillip J. Wolfram, Katrina Bennett +1
A tensor provides a concise way to codify the interdependence of complex data. Treating a tensor as a d-way array, each entry records the interaction between the different indices.…
Operator algebras generated by left invertibles
Derek DeSantis
Operator algebras generated by partial isometries and their adjoints form the basis for some of the most well studied classes of C*-algebras. The primary object of this paper is th…
