Linear stability analysis of the Lloyd algorithm on a circle

Silpi Saha, Sangita Jha, Mrinal Kanti Roychowdhury

Lloyd algorithm is the standard iterative method for computing quantizers and codebooks in source coding and vector quantization. In this article, we study the dynamical and stabil…

Optimal Quantization for Nonuniform Densities on Spherical Curves

Silpi Saha, Sangita Jha, Mrinal Kanti Roychowdhury

We present an analysis of optimal quantization of probability measures with nonuniform densities on spherical curves. We begin by deriving the centroid condition, followed by a hig…
