A component is an independently deliverable set of reusable services. Component-Based System (CBS) is a promised approach to build applications from deployed components. It provides efficiency, reliability, maintainability. Interpreting the results of performance analysis and generating an alternative design to build system from components is a great challenge in the software performance domain...

Traditional bidirectional two-dimension (2D) principal component analysis ((2D)PCA-L2) is sensitive to outliers because its objective function is the least squares criterion based on L2-norm. This paper proposes a simple but effective L1-norm-based bidirectional 2D principal component analysis ((2D)PCA-L1), which jointly takes advantage of the merits of bidirectional 2D subspace learning and L1...

In the sponsored search system, advertisers bid on keywords that are related to their products or services to participate in repeated auctions and display their ads on the search result pages. Since there is a huge inventory of possible terms, instructive keyword recommendation is an important component to help advertisers optimize their campaigns and improve ad monetization. In this paper, by ...

After twenty years, Extenics made great progress in innovation theory, formal method and real application. Through the formalized research for its logical cell basic-element, the information-knowledge-strategy formalized system, extension analysis methods, extension transformation methods and superiority evaluation methods are set up. We introduce Extenics theory to describe, analyze and evalua...
