Fouille visuelle et classification de données par nuage d'insectes volants
RÉSUMÉ. Nous présentons dans cet article un nouvel algorithme biomimétique permettant de créer des groupes au sein de données et de les visualiser dynamiquement. Cet algorithme s’inspire des insectes volants se déplaçant en nuage en créant des mouvements complexes à partir de règles locales simples. Chaque insecte représente une donnée. Le déplacement des insectes vise à créer des groupes de do...
متن کاملFast 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...
متن کاملAdditive 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...
