Two-way latent grouping model for user preference prediction
TL;DR: A novel latent grouping model for predicting the relevance of a new document to a user and compared it against a state-of-the-art method, the User Rating Profile model, where only users have a latent group structure.

Analyzing word frequencies in large text corpora using inter-arrival times and bootstrapping
TL;DR: In this paper, the authors propose two methods for modeling word frequencies that both take into account the occurrence patterns of words and go beyond the bag-of-words assumption, based on the spatial distribution of individual words in the language.
Book ChapterDOI
On discriminative joint density modeling
TL;DR: The framework is used to derive generative models for generalized linear models, including logistic regression, linear discriminant analysis, and discriminative mixture of unigrams, which are easy to extend the models and interpret the results.
Visual Analytics: Final report
TL;DR: In this article, the authors present a case study of meteorological services in South Eastern Europe with potential benefits in Albania, Bosnia-Herzegovina, FYR Macedonia, Moldova and Montenegro.
