Rolled Gaussian process models for curves on manifolds
Simon Preston, Karthik Bharath, Pablo Lopez-Custodio +1
Given a planar curve, imagine rolling a sphere along that curve without slipping or twisting, and by this means tracing out a curve on the sphere. It is well known that such a roll…

A cheat sheet for probability distributions of orientational data
P. C. Lopez-Custodio
The need for statistical models of orientations arises in many applications in engineering and computer science. Orientational data appear as sets of angles, unit vectors, rotation…
