Fast and accurate multigrid solution of Poissons equation using diagonally oriented grids

We solve Poisson’s equation using new multigrid algorithms that converge rapidly. The novel feature of the 2D and 3D algorithms are the use of extra diagonal grids in the multigrid hierarchy for a much richer and effective communication between the levels of the multigrid. Numerical experiments solving Poisson’s equation in the unit square and unit cube show simple versions of the proposed algo...

Additive Co-Clustering of Gaussians and Poissons for Joint Modeling of Ratings and Reviews

Understanding a user’s motivations provides valuable information beyond the ability to recommend items. Quite often this can be accomplished by perusing both ratings and review texts, since it is the latter where the reasoning for specific preferences is explicitly expressed. Unfortunately matrix factorization approaches to recommendation result in large, complex models that are difficult to in...

Decoding spike trains instant by instant using order statistics and the mixture-of-Poissons model.

In the brain, spike trains are generated in time and presumably also interpreted as they unfold in time. Recent work (Oram et al., 1999; Baker and Lemon, 2000) suggests that in several areas of the monkey brain, individual spike times carry information because they reflect an underlying rate variation. Constructing a model based on this stochastic structure allows us to apply order statistics t...
