Two-Way Grouping by One-Way Topic Models
Abstract. We tackle the problem of new users or documents in collaborative filtering. Generalization over users by grouping them into user groups is beneficial when a rating is t...

Application of Reduce Order Modeling to Time Parallelization
We recently proposed a new approach to parallelization, by decomposing the time domain, instead of the conventional space domain. This improves latency tolerance, and we demonstrat...

Mining complex models from arbitrarily large databases in constant time
In this paper we propose a scaling-up method that is applicable to essentially any induction algorithm based on discrete search. The result of applying the method to an algorithm ...

Impact of modern memory subsystems on cache optimizations for stencil computations
In this work we investigate the impact of evolving memory system features, such as large on-chip caches, automatic prefetch, and the growing distance to main memory on 3D stencil ...

Investigating hidden Markov models capabilities in anomaly detection
Hidden Markov Model (HMM) based applications are common in various areas, but the incorporation of HMM's for anomaly detection is still in its infancy. This paper aims at cla...
