A primal-dual interpretation of two 2-approximation algorithms for the feedback vertex set problem in undirected graphs
Recently, Becker and Geiger and Bafna, Berman and Fujito gave 2-approximation algorithms for the feedback vertex set problem in undirected graphs. We show how their algorithms can...

Learning Sets of Sub-Models for Spatio-Temporal Prediction
In this paper we describe a novel technique which implements a spatiotemporal model as a set of sub-models based on ļ¬rst order logic. These sub-models model diļ¬€erent, typicall...
