-.Internet is today full of structured or unstructured information. and this information is directly or indirectly influencing society or peoples. Because today internet is part our daily life activity. But using this abundant and ambiguous in most efficient manner in useful decision making is still a big challenge. During our web surfing either it is online shopping or blogging or using tweets...
The merits of different signal preprocessing schemes for speech recognizers are usually assessed purely on the basis of the resulting recognition accuracy. Such benchmarks give a good indication as to whether one preprocessing is better than another, but little knowledge is acquired about why it is better or how it could be further improved. In order to gain more insight in the preprocessing, w...
Preprocessing is one of the main components in a conventional document categorization (DC) framework. This paper aims to highlight the effect of preprocessing tasks on the efficiency of the Arabic DC system. In this study, three classification techniques are used, namely, naive Bayes (NB), k-nearest neighbor (KNN), and support vector machine (SVM). Experimental analysis on Arabic datasets revea...
Reverse Combinatorial auctions, that is, auctions where bidders can bid on the supply right of combinations of items, tend to lead to more efficient allocations than traditional auction mechanisms in multi-item auctions where the agents' valuations of the items are not additive. A common model is formulated for optimal the winner determination problem of reverse combinatorial auction. A PRIM (P...
Matrix assisted laser desorption ionization time-of-flight (MALDITOF) is one of the highthroughput mass spectrometry (MS) technologies, producing data requiring an extensive preprocessing before subsequent analyses. In the last years, various preprocessing techniques have been developed for different tasks, including baseline correction, smoothing, normalization, peak detection and peak alignme...
