Combinatorial rigidity of Incidence systems and Application to Dictionary learning
Meera Sitharam, Mohamad Tarifi, Menghan Wang
Given a hypergraph with hyperedges and a set of \emph{pinning subspaces}, i.e.\ globally fixed subspaces in Euclidean space , a \emph{pinned subspace-…
An Incidence Geometry approach to Dictionary Learning
Meera Sitharam, Mohamad Tarifi, Menghan Wang
We study the Dictionary Learning (aka Sparse Coding) problem of obtaining a sparse representation of data points, by learning \emph{dictionary vectors} upon which the data points c…
Learning Hierarchical Sparse Representations using Iterative Dictionary Learning and Dimension Reduction
Mohamad Tarifi, Meera Sitharam, Jeffery Ho
This paper introduces an elemental building block which combines Dictionary Learning and Dimension Reduction (DRDL). We show how this foundational element can be used to iterativel…
Real Mutually Unbiased Bases
P. Oscar Boykin, Meera Sitharam, Mohamad Tarifi +1
We tabulate bounds on the optimal number of mutually unbiased bases in R^d. For most dimensions d, it can be shown with relatively simple methods that either there are no real orth…
