This paper addresses feature extraction criterion function of multi-layer feed forward neural networks with linear output units and nonlinear hidden units. From the minimum mean square error function of the network output, the paper uses the nature of matrix trace and singular value decomposition, deduces the formula for calculating the nonlinear criterion(More)
The financial problems often relate to many stochastic differential equations which is difficult to solve. Based on the traditional numerical methods for solving determinate ordinary differential equations (ODEs), the paper presents the numerical methods of stochastic ordinary differential equations (SODEs). The numerical methods mainly considered in the(More)
Decision Suppose System is playing an important role in computer science, technology and engineering, while intelligent decision-making is one of the current hotspots. Intelligent decision-making methods and their algorithms are one of the most important basics and key cores in intelligent information processing, intelligent pervasive computing and so on.(More)
In this paper, a representative algorithm convex hull with half-dividing and recurrence is commented; and according to the isomorphic fundamental theorem of the convex hull construction, a more efficient new algorithm to find a convex hull based on the dynamical base line with a maximum pitch of the dynamical base line is given. The general characters of(More)
At present the problems that people want to solve anxiously are: facing the huge information data pool, how to carry on the effective data mining; in the highly dynamic information source which is the standard to the importance of the information and the degree paid attention to, how to seek the ldquofocusrdquo (namely focus information) from the society,(More)
Web application servers (WASs) are middleware platforms for deployment and execution of component-based web applications. To cater for an increasingly diverse range of QoS demands, WAS must be capable of adaptation during execution to modify itself and to respond to changing conditions in its external environment. To accommodate such changes, WAS should(More)
