Performance Evaluations of Replacement Algorithms in Hierarchical Web Caching
Abstract. Web caching plays an important role in many network services. Utilization of the cache in each level (server, proxy, and client) of network forms a web caching hierarchy....

Face detection using coarse-to-fine support vector classifiers
We describe a new face detection algorithm based on a hierarchy of support vector classifiers (SVMs) designed for efficient computation. The hierarchy serves as a platform for a c...

On Worst-Case to Average-Case Reductions for NP Problems
We show that if an NP-complete problem has a non-adaptive self-corrector with respect to a samplable distribution then coNP is contained in NP/poly and the polynomial hierarchy co...

Factorization with morton-ordered quadtree matrices for memory re-use and parallelism
Quadtree matrices using Morton-order storage provide natural blocking on every level of a memory hierarchy. Writing the natural recursive algorithms to take advantage of this bloc...
