Description

Holonomic gradient method is a elegant implementation of ODE techniques for efficiently evaluating normalising constants. In the talk we show how to apply this approach to Fisher-Bingham distributions defined on the sphere. Such normalising constants are not available in a closed form and their accurate evaluation is essential for performing the statistical inference with them. This enables us to further develop a new algorithm for shape analysis.
