Quantization for uniform distributions on hexagonal, semicircular, and elliptical curves
Gabriela Pena, Hansapani Rodrigo, Mrinal Kanti Roychowdhury +2
In this paper, first we have defined a uniform distribution on the boundary of a regular hexagon, and then investigated the optimal sets of -means and the th quantization err…
High Precision Numerical Computation of Principal Points For Univariate Distributions
Santanu Chakraborty, Mrinal Kanti Roychowdhury, Josef Sifuentes
Principal points were first introduced by Flury: for a positive integer , principal points of a random variable are the points that minimize the mean squared distance be…
Randomized methods for rank-deficient linear systems
Josef Sifuentes, Zydrunas Gimbutas, Leslie Greengard
We present a simple, accurate method for solving consistent, rank-deficient linear systems, with or without addi- tional rank-completing constraints. Such problems arise in a varie…
