This paper presents two efficient and compact Matlab codes of Subset Simulation for reliability analysis and structural optimization. The codes for reliability analysis and structural optimization comprise of the direct Monte Carlo and Markov Chain Monte Carlo. The theoretical and numerical elements of Subset Simulation are briefly presented in this paper, as well as the detailed instructions to implement...
Formal Concept Analysis (FCA) is a principled way of automatically deriving ontology from larger textual data and interested by many researchers. Central of FCA is a pure and well defined formal context. Exploiting documents with characteristic words to form formal context, denoted as textual formal context (TFC), which lead to generate a highly sparse two-dimensional space with lots of noise. It...
In order to improve low efficiency conducted in text classification and measuring similarity using vector space model for representing text. This paper proposed a method for reducing feature items of feature vector based on thesaurus. It used semantic relation of thesaurus such as Y, D, F, S, C symbol to merge and reconstruct the feature items. And then the method was applied to formal concept analysis...
The increasing widely application of Virtual Reality (VR) technology in the field of education provides novel means and methods for the modern teaching and education. The cooperative learning is a kind of teaching method that the specific teaching target cooperatively completed by multiple learners. The paper introduced VR technology into cooperative learning and constructed a Network Cooperative...
