Direct Simulation of Poisson and Newton Kernel Distributions

The Poisson kernel-based (PKB) distribution is a flexible and numerically convenient family on the unit sphere used for model-based clustering, uniformity testing, and directional data analysis. Available random variate generators rely on rejection from a von Mises-Fisher, angular central Gaussian, or projected Saw env...

Spherical Cauchy Variational Autoencoders: Heavy Angular Tails and Exact KL Evaluation

The spherical Cauchy distribution is developed as a hyperspherical posterior that needs neither compromise and has broader angular tails and a smaller KL penalty than both alternatives, so equal local precision costs less regularization.
