This paper proposes a new attribute construction approach which converts the original data attributes into a higher dimensional feature space to extract more attribute information by a similarity-based algorithm using the classification-oriented fuzzy membership function. Seven data sets with different attribute sizes are employed to examine the performance of the proposed method. The results show […]
Exploiting Excess Capacity to Improve Robustness of WDM Mesh Networks
Excess capacity (EC) is the unused capacity in a network. Excess capacity management techniques exploit the EC to improve the network performance. In this paper we propose EC management techniques that exploit EC to improve all the three performance metrics. EC management techniques differ in two respects: when connections are migrated from one protection scheme […]
Identify the location of fault in Web Application using Enhanced Technique
The proposed system use existing fault localization technique likeTarantula, Ochiai, and Jaccard. These techniques predict the location of a fault by computing, for each statement, the percentages of passing and failing tests that execute that statement. The enhanced source mapping is a new technique to localize faults effectively in web applications written in PHP by […]
Multiple Exposure Fusion for High Dynamic Range Image Acquisition
A multiple exposure fusion to enhance the dynamic range of an image is proposed. The construction of high dynamic range images (HDRIs) is performed by combining multiple images taken with different exposures and estimating the irradiance value for each pixel. This is a common process for HDRI acquisition. During this process, displacements of the images […]
DCS: Distributed Asynchronous Clock Synchronization in Delay Tolerant Networks
In this paper, we propose a distributed asynchronous clock synchronization (DCS) protocol for Delay Tolerant Networks (DTNs). Different from existing clock synchronization protocols, the proposed DCS protocol can achieve global clock synchronization among mobile nodes within the network over asynchronous and intermittent connections with long delays. Convergence of the clock values can be reached by […]
Mutual Information-Based Supervised Attribute Clustering for Microarray Sample Classification
Microarray technology is one of the important biotechnological means that allows to record the expression levels of thousands of genes simultaneously within a number of different samples. An important application of microarray gene expression data in functional genomics is to classify samples according to their gene expression profiles. Among the large amount of genes presented […]
Horizontal Aggregations in SQL to Prepare Data Sets for Data Mining Analysis
Preparing a data set for analysis is generally the most time consuming task in a data mining project, requiring many complex SQL queries, joining tables, and aggregating columns. Existing SQL aggregations have limitations to prepare data sets because they return one column per aggregated group. In general, a significant manual effort is required to build […]
