To cope with time-attribute and variations of event distribution in dynamic evolving process, an streaming process mining based on time series prediction and hybrid heuristic miner is proposed. A heuristic miner is improved based on post-task of activity in event logs to optimize the initial particle distribution for Particle Swarm Optimization. Furthermore, “aging factor” based on time series attribute...
Several simple sequence repeats (SSRs) have been demonstrated to regulate gene functions, and SSR mutations in a disease gene may cause different genetic disorders. In order to identify putative functional SSR patterns, a Web system for discovering significant associations between SSR motifs and gene ontology (GO) terms was developed in this study. The system is named as GOSH: Gene Ontology SSR Hierarchy...
Due to homonyms, abbreviations, etc., name ambiguity is widely available in Web and e-document. For example, when integrating heterogeneous literature databases, because there are different name specifications, different authors may be thought of as the same author, and vice versa. Therefore, name ambiguity makes data robust even dirty and lowers the precision of information retrieval. In this paper,...
Although decision tree learning has achieved great success in building classifier, most existing methods don't pay attention to unequal weights between different instances from training and testing data sets. However, many real world data sets are imbalanced in nature. In this paper, we introduce a new improved decision tree based weights, which considers imbalanced weights between different instances,...
The dominance of the Internet in our lives sees permanent changes of how marketers conduct their marketing and measure their marketing performance. Traditional measurement methods fall short for not being timely and effective. In this study, we propose the use of Web data, in a quantitative metric, to assess market impact of brands. The metric consists of three independent dimensions, covering measures...
The equivalent extraction of unknown logical chip is a new technology in the chip test and malfunction inspection. From the traditional design flow of logical chips, the expression form of logical chips in different design phases was abstracted, which thereby proves theoretically the feasibility of the transformation from work waveform to chip logical expression. With emphasis laid on the qualification...
In this paper, we studied the characteristic of the data acquired by both the combinatory logic electric circuit and the timing circuit. And with the emphasis laid on the consideration of representation requirements in the situations with and without feedback, the paper established the format suitable for both. Through the analysis of the requirements of truth table data characteristics during the...
We address ranging energy optimization for an unsynchronized localization system, which features robust sensor positioning, in the sense that specific accuracy requirements are fulfilled within a prescribed service area. Optimization problems related to the ranging energy of a sensor and beacons are proposed, after which a practical algorithm based on semidefinite programming is presented. The effectiveness...
An image fusion system using a fuzzy biorthogonal wavelet transform technique is proposed and justified in this paper. The basic fuzzy sets are defined on the low-high, high-low, and high-high spatial frequency bands at different scales of biorthogonal wavelet transform on the visible light images and infrared images. The simulation results demonstrate the effectiveness of the fusion scheme in this...
