In many applications, one can obtain descriptions about the same objects or events from a variety of sources. As a result, this will inevitably lead to data or information conflicts. One important problem is to identify the true information (i.e., the truths) among conflicting sources of data. It is intuitive to trust reliable sources more when deriving the truths, but it is usually unknown which...
Concept Factorization (CF) is a modified version of Nonnegative Matrix Factorization (NMF) and both of them have been proved to be effective matrix factorization methods for dimensionality reduction and data clustering. However, CF is essentially an unsupervised method which cannot utilize any prior knowledge of data. In this paper, we propose a new semi-supervised concept factorization method, called...
Transfer entropy reflects the varing trends of two signals. It can show the dynamic and directional information between two systems and can be applied to analysis nonlinear systems better than mutual information. In this article we apply transfer entropy to ECG signals, which extracts from the MIT-BIH ECG signal database. We compute the transfer entropy of ECG signals for different people and make...
Due to the exponentially growing bioinformatics databases and rapidly popular of GPU for general purpose computing, it is promising to employ GPU techniques to accelerate the sequence search process. Hmmsearch from HMMER bioinformatics software package is a wildly used software tool for sensitive profile HMM (Hidden Markov Model) searches of biological sequence databases. In this paper, we implement...
Sigma factors play important roles in transcriptional regulation in bacteria. Streptomyces coelicolor, a soil bacterium which is best known for its production of a variety of antibiotics, possesses a sophisticated transcriptional machinery. Among 58 sigma factors identified in the genome, 44 are extra-cytoplasmic function (ECF) sigma factors, which coordinate cellular responses to external signals...
With the intensive development of university information system, the increasingly expanding and accumulating historical data seriously affects the efficiency of information system performance and brings data management and storage difficulty. In view of university's data characteristics, connected with the authors' experience of data archiving in data management, in this paper the authors put forward...
Identification of non-native personnel is a critical piece of information for making crucial on-the-spot decisions for security purposes. Identification of a non-native speaker is often readily apparent in normal conversation with a native speaker through speech content and accent. Such identification which requires familiarity with language nuances may not be possible for a non-native interrogator...
Geographical centralized e-commerce has a lot of defects. Based on the characteristics of P2P and Web Services technology, a decentralized e-commerce architecture is proposed in this paper, which can solve the problems such as the difficulties of resource reorganization, cross-platform, database maintenance and so on, which can hardly be settled in existing geographical centralized e-commerce. So...
Computer-based water body environment monitoring and management are effective methods to protect water body resources. The monitoring and management information for environmental monitoring originates from environmental laboratories. The current environmental monitoring and management of the existence of information processing is too slow to meet the requirements. Water body monitoring and management...
China is one of the countries in the world that suffer serious natural disasters. Frequent and serious biological disasters cause great damage to crop production. The plant disease data of multiform could be analyzed and then a forecasting report was made.This article according to characteristic of the plant disease, introduced forecasts system's design and key technologies realization based on data...
