In Internet applications, Web object prefetching is a commonly used and quite effective algorithmic approach to reduce user perceived delays. While a separate concept, prefetching is closely related to caching and they are often blended together in Web algorithms. In this paper, we give a review of Web prefetching models and algorithms, categorize them into groups based on their design principles,...
A method for explaining results of a regression based classifier is proposed. The data is clustered using a metric extracted from the classifier. This way, clusters found are related to classifier predictions, and each cluster can be considered a possible explanation for classification result. The clusters are described by simple rules, meant to be easy for a human to understand. The key points of...
A flexible and scalable architecture that implements real-time synthetic aperture sonar (SAS) imaging on high performance clusters (HPCs) is introduced in this paper. Combing HPCs with application of a hybrid MPI and OpenMP parallel programming model, the lookup table algorithm for SAS image reconstruction based on the time-domain correlation algorithm is realized in parallel. Considering the huge...
