Pattern Mining on Stars with FP-Growth
Abstract. Most existing data mining (DM) approaches look for patterns in a single table. Multi-relational DM approaches, on the other hand, look for patterns that involve multiple ...

Earth Mover’s Prototypes: a Convex Learning Approach for Discovering Activity Patterns in Dynamic Scenes
We present a novel approach for automatically discovering spatio-temporal patterns in complex dynamic scenes. Similarly to recent non-object centric methods, we use low level visu...

Improving Database Performance on Simultaneous Multithreading Processors
Simultaneous multithreading (SMT) allows multiple threads to supply instructions to the instruction pipeline of a superscalar processor. Because threads share processor resources,...

Multi-clip Query Optimization in Video Databases
A multi-clip query requests multiple video clips. In this paper we address the multi-clip query optimization problem. We propose a new heuristics called Restricted Search Interval...
