Background Multiple layers of genetic and epigenetic variability are being simultaneously explored in an increasing number of health studies. We summarize here different approaches applied in the Data Mining and Machine Learning group at the GAW20 to integrate genome-wide genotype and methylation array data. Results We provide a non-intimidating introduction to some frequently used methods to investigate...
With the advent of the era of network, video surveillance technology is more and more integrated into the IT emerging technologies. Big data technology in the field of video surveillance has shown a broad development path. The research of surveillance video data mining based on big data is committed to achieve a perfect fusion of the big data technology and video surveillance business, in order to...
Complex social issues can be better addressed collaboratively by stakeholders through democratic decision-making. A key prerequisite for engaging the public is the ability to gather what we know about a public issue and present such knowledge in a concise fashion. This is commonly done through a citizen's panel who performs collaborative information seeking and analysis. The outcome of such process...
Traditional text information extraction methods mainly act on static documents and are difficult to reflect the dynamic evolvement of information update on the web. To address this challenge, this work proposes a new method based on shallow parsing with rules. The rules are generated according to the syntactic features of English texts, such as the tense of verbs, the usages of modal verbs and so...
In this paper, we present a practical method of sentence ordering in multi-document summarization tasks of Chinese language. By using Support Vector Machine (SVM), we classify the sentences of a summary into several groups in rough position according to the source documents. Then we adjust the sentence sequence of each group according to the estimation of directional relativity of adjacent sentences,...
Vehicle network is popular gradually. For more security in vehicle network, a trusted AAA (Authentication, Authorization and Accounting) environment for vehicle network must be established. The paper proposes an approach to establish such an environment using combination of two next generation AAA protocols, PANA (Protocol for carrying Authentication for Network Access) and Diameter. The ability of...
Stack filters are a class of nonlinear digital filters that satisfy a weak superposition property known as the threshold decomposition and stacking property. They have good performances of suppressing noises and preserving details. Their design is formulated as a course of optimizing PBF. This paper presents an ant colony-clonal selection algorithm for stack filters' optimizing. Under the MMAE criterion,...
Template matching has been brought effective results in road tracking. Actually, the shape of template plays a very important role. In this paper, a novel circular template is utilized to search the center points of the road. The circular template is not necessary to rotate for the isotropy of template when searching the optimal road axis point, which means less computation. At the same time, least...
Classification is a well-studied problem in data mining. Classification performance was originally gauged almost exclusively using predictive accuracy, but as work in the field progressed, more sophisticated measures of classifier utility that better represented the value of the induced knowledge were introduced. Nonetheless, most work still ignored the cost of acquiring training examples, even though...
