Modeling large cortical networks with growing self-organizing maps
Self-organizing computational models with specific intracortical connections can explain many features of visual cortex. However, due to their computation and memory requirements,...

Multiscale Detection of Gesture Patterns in Continuous Motion Trajectories
Abstract. We describe a numerical method for scale invariant detection of gesture patterns in continuous 2D motions. The algorithm is fast due to our rejection-based reasoning achi...

On the Connectivity and Multihop Delay of Ad Hoc Cognitive Radio Networks
—We analyze the multihop delay of ad hoc cognitive radio networks, where the transmission delay of each hop consists of the propagation delay and the waiting time for the availab...

Lossy Conservative Update (LCU) Sketch: Succinct Approximate Count Storage
In this paper, we propose a variant of the conservativeupdate Count-Min sketch to further reduce the overestimation error incurred. Inspired by ideas from lossy counting, we divid...

Achieving Scalable Parallelization for the Hessenberg Factorization
—Much of dense linear algebra has been successfully blocked to concentrate the majority of its time in the Level 3 BLAS, which are not only efficient for serial computation, but...
