In the daily audit work, informationization brings huge amounts of business data. Auditors face huge amounts of data, and personnel allocation has no planned way. In order to solve these practical problems, we introduce the data mining technology. Isolated point algorithm based on unit is applied to computer network audit. Boundary cell value of the isolated point algorithm is adjusted. By means of...
Multi-label learning task is using to solve problems of syndrome diagnosis for patients may simultaneously have more than one syndrome in traditional Chinese medicine (TCM). The two goals of multi-label learning are label prediction loss and relevance ordering loss. Most Multi-label learning algorithms focus on only one of the goals and neglect the other one. However, there is a multi-label learning...
In order to ensure the security and stability of the line, it is important that the sag of transmission line is regularly tested, and the key for the method of sag calculation based on the image processing is how to precisely extract the interested single power line feature. On the base of fully analyzing the special linear characteristics of power line images, the optimized SURF algorithm is proposed...
A Cyber-Physical System (CPS) is a system featuring a tight combination and coordination of the system's computational and physical elements. CPS integrates the executive ability of the physical world and the intelligence of the cyber world to add new capabilities to real-world physical systems. Recent years has witnessed the thriving of various applications in Cyber-Physical Networked System (CPNS),...
Evaluating classifier performances is a crucial problem in pattern recognition and machine learning. In this paper, we propose a new measure, i.e. confusion entropy, for evaluating classifiers. For each class cli of an (N+1)-class problem, the misclassification information involves both the information of how the samples with true class label cli have been misclassified to the other N classes and...
Microarray data analysis based on gene expression profiles is attracting more and more attention from researchers for finding functional genes and for classifying diseases. Various available approaches for selecting features and for classification can be exploited to manipulate such data. However, fewer methods can be elegantly adapted to accomplish this purpose. The main challenge is that such microarray...
In this paper, a novel time-of-arrival estimation algorithm is proposed for impulse radio-based UWB systems in dense multipath environment. In particular, a dedicated ranging sequence with good cross-correlation property is proposed and a threshold-based search-back unit is introduced, with the purpose of supporting high-precision ranging even at low signal-to-noise ratio. An approximate closed-form...
