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...
This paper focuses on the multiple attribute decision making problems with the attribute values being linguistic evaluations. The decision matrix is normalized by calculating the grey relation coefficients of linguistic attribute values to their corresponding positive ideal one. Furthermore, a mathematical programming model is set up to figure out the attribute weights with the overall values of the...
Based on diffeomorphism equivalent transformation and backstepping technology, a feedback control law is proposed for a three-DOF underactuated surface vessel with nonholonomic acceleration constraints. With the aids of Lyapunov redesign and high gain feedback techniques, the system under disturbances displays the robust characteristics. All signals in the closed-loop system are proved uniformly ultimately...
The water injection system of large-scale oilfield is a very complicated pressure system, which consists of several water injection stations connecting with each other. At present, the system suffers a couple of prevailing problems, for example, low injection efficiency and high power consumption, and the dispatching and optimization of the system operation serves as an important approach to solve...
Word sense acquisition and distinction are key issues for both lexicography and lexical semantic processing. However, it is quite difficult to automatically acquire word senses and to further evaluate the results with the lexica, which more likely bear the different findings of word sense distinction and granularity. In this paper, we'd like to put forward the idea of measuring word polysemousness...
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...
This paper proposes a new face recognition approach by using Independent Component Analysis (ICA) and Ensemble Classifiers based on Support Vector Machine (SVM). Firstly, to improve the quality of the face images, a series of image pre-processing techniques are used. Then the ICA based on Kernel Principal Component Analysis (KPCA) and FastICA is employed to extract features. At last, appropriate classifiers...
