WebNov 11, 2014 · Steffen L. Lauritzen is an internationally highly recognized statistician who has made profound contributions to a broad range of areas in statistical science. He is one of the leading experts in the world on graphical models, a very active research field at the boundary between statistics and computer science. WebProbabilistic graphical models (Lauritzen (1996)) have become an important scientific tool for finding and describing patterns in high-dimensional data. Learning a graphical model from data requires a simultaneous estimation of the graph and of the probability distribution that factorizes according to this graph. In the Gaussian case, the ...
