The Marr wavelet pyramid
We introduce a new semi-orthogonal complex wavelet basis of L2(R2 ). The basis functions are associated to the complex gradient-Laplace operator, which plays a central role in ima...

Fast direct policy evaluation using multiscale analysis of Markov diffusion processes
Policy evaluation is a critical step in the approximate solution of large Markov decision processes (MDPs), typically requiring O(|S|3 ) to directly solve the Bellman system of |S...

Shortest paths on 3-D simple Lie groups with nonholonomic constraint
— In this paper we study the Carnot-Caratheodory metrics on SU(2) S3 , SO(3) and SL(2) induced by their Cartan decomposition and by the Killing form. Besides computing explicitly...
