This paper studies the problem of synchronization on a complex dynamical network where the nodes' dynamics are nonlinear time-invariant systems and share a directed communication network. Firstly, we study the problem of synchronization on a directed network with physical links. An explicit Lyapunov function is constructed by using an appropriate matrix to derive the threshold of event generator....
Handwritten character recognition has been an active and challenging research problem, due to the large variations of characters and the dependency relationship between characters. Most of traditional methods rarely consider these two challenges simultaneously. This paper proposes a sequential convolutional neural network(CNN) to solve this problem. It considers handwritten words as image sequences...
Computer networks are inevitably attacked as a result of their openness, while network attack usually actualized by exploiting vulnerability existing in network environment. Attack graph, consisted of lots of related atomic attacks, can fully display the exploitation and dependence relations among all of the vulnerabilities existed in network. Thus, it is a very useful tool for network vulnerability...
Recently, combining Conditional Random Fields (CRF) with Neural Network has shown the success of learning high-level features in sequence labeling tasks. However, such models are difficult to train because of the increase of the parameters to tune which needs enormous of labeled data to avoid over fitting. In this paper, we propose a transfer learning framework for the sequence labeling task of gesture...
Compound model PSO with stochastic inertia weight is put forward and used to optimize the parameters of wavelet neural network. The trained wavelet neural-network is applied to choosing tested position of gearbox. It is an available approach to solve the problems on choosing tested position in fault diagnosis.
With the increasingly prominent serious problems of social aging population, special attention should be paid to social sustainable development. Taking the social promotion of universal design of the aging as premise, this paper tries to study its influence and the concrete effectiveness in such areas as resources conservation, enterprise development, social harmony and so on. In terms of respect...
The collection vehicle routing problems with intermediate facilities (CVRP-IF) is actually belong to a well-known generalization of VRP, the Multi-Depot Vehicle Routing Problem with Inter-Depot Routes (MDVRPI), which is a combinatorial optimization problem and holds a central place in reverse logistics management, such as waste collection management. This paper presents an improved multiple ant colony...
This paper proposes a Statistical Regression Algorithm, According to the number of node visited, it generates the dynamic menu of the IVR (Interactive Voice Response) system. The algorithm is implemented through IVR application gateway which is very important for the IVR system. The voice files of data demanded are built and played for response through application gateway, TTS(Text to Speech) and...
Outlier detection is a hot topic of data mining. After studying the existing classical algorithm of detecting outliers, this paper proposes a new algorithm for outlier detection based on offset, and makes a new definition for outlier. This detection algorithm is a method based on clustering analysis. It includes cluster modeling and data detection. Also, the clustering result obtained together with...
Under static frequency allotment scheme, each licensed operator is allocated a frequency band in which its user can transmit, but the spectrum may not be fully utilized either on geographical or at temporal level. On the other hand, on some hot spot business frequency bands, spectrum resources become in short supply. Dynamic spectrum access (DSA) technology based on cognitive radio is an effective...
