As is well known, nonnegative matrix factorization (NMF) is a popular nonnegative dimensionality reduction method which has been widely used in computer vision, document clustering, and image analysis. However, traditional NMF is an unsupervised learning mode which cannot fully utilize the priori or supervised information. To this end, semi-supervised NMF methods have been proposed by incorporating...
The network dynamic evaluation is in the proven prescription legal science has truthfully given the trusted degree of the network from the real network to the simulation experiment evaluation concrete model and the realization process. The network modelling process uses the extraction real network data, establishes the simulation environment, under the simulation environment destructive collapse test...
In order to evaluate the ability of personnel training of the university accurately, combined talents teaching and research condition in engineering colleges and universities, this paper constructs a comprehensive evaluation index system of cultivation of innovative talents in engineering colleges and universities and propose a method of comprehensive evaluation based on Particle Swarm Optimization...
In order to evaluate efficiency in university laboratory in a reasonable way, the index system for efficiency evaluation is established, and the efficiency class is separated into three classes-good, fair, and poor. To classify the efficiency of three classes, the evaluation model of multi-layer support vector machines (SVM) classifier is established. In order to verify the effectiveness of the method,...
