The topic detection of university BBS (Bulletin Board System) plays an important role in studying university students' hottest attention, and it presents the trend of campus opinion. Existing topic model use word probability distribution to represent topic, which lacks of interpretability, and it's difficult to express an unified meaning. What's more, university BBS has its own characteristics and...
Early event prediction challenges most of existing modeling methods especially when dealing with complex spatio-temporal data. In this paper we propose a new method for predictive data modelling based on a new development of the recently proposed NeuCube spiking neural network architecture, called here NeuCube(ST). The NeuCube uses a Spiking Neural Network reservoir (SNNr) and dynamic evolving Spiking...
Interpersonal communication is supported by many new technologies nowadays. It has important influence on information diffusion. To study the dynamics of interpersonal communication, an agent-based model is built. The model simulates the process that agents construct their global cognitive social network through communication with local neighbors. Agents communicate with each other through social...
An exact fingerprint image segmentation improves the accuracy of automatic fingerprint identification system and reduces the processing time of follow-up process. A novel fingerprint image segmentation method based on linear Support Vector Machine (SVM) is proposed to overcome the shortcomings of present approaches shown in previous literatures. Feature vectors are constructed by Fourier spectrum...
In order to create a safe and harmonious cyberspace environment for youth and protect them from the impact of bad information such as pornography, violence and gambling, most of the current solutions are to shield the sites containing this information. However some youth will take the initiative to seek out this bad information. In this paper we propose a method to analyze the searching behavior of...
Triggered by a spat between China's two top Internet firms, this paper explores the legal system concerning the protection of the right to online privacy in mainland China by an international and comparative study, with special reference to that of EU. The authors point out that all the problems of existing laws and regulations concerning the protection of the right to online privacy should be regarded...
Singular points (SPs) in fingerprint images have important applications in fingerprint recognition such as registration and classification. Reliable detection of SPs could sufficiently improve processing speed and performance of automatic fingerprint identification system. In this paper, an improved SPs detection method is proposed. We first present a new algorithm of fingerprint image segmentation...
