Latent Semantic Indexing is a widely used text mining technology nowadays due its effectiveness in dealing with the problems of synonymy and polysemy within a proper matrix scale. However LSI is enormously computationally intensive especially for processing large scale data. And effective solution is to increase the computational power available to LSI using multiple computing nodes. In this paper...
Grid system is inclined to support resource sharing for mixed types of workloads nowadays to improve the whole user utility, which requires an effective allocation method that not only each workload user can have desirable resources to satisfy its performance requirement from the view of user, but also can avoid shortage or waste of resources from the view of system. Currently, most resource allocation...
This paper studies evaluation problem in psychological health. Based on the psychological dimensions and the actual evaluation work, we propose a kind of generalized linear regression model with convex constraint, named as Evaluation Model, in which the dependent variable and regression coefficients all are unknown. We analyze the algorithm of the model with linear regression method. Then the least...
Web hot topic prediction is now one of the most significant research focus in Web data mining, which can reflect the Internet users' psychosocial predilection, may greatly benefit us. Markov and neural network are such two typical traditional prediction model, however, the Markov method can neither capture nor express the statistical property of the real data while the computation of neural network...
