This paper provides a algorithm, which is based on that kernelized fuzzy C-means uses on the study of source code mining, to solve the problem that the large number of quantities, multiple attributes and most of them discrete of software engineering. By using this algorithm, we can improve the efficiency of mining and seek faster and more effective cluster approaches. Meanwhile, we can also solve...
Variable-weight optical orthogonal code (OOC) was introduced by G-C Yang for multimedia optical CDMA systems with multiple quality of service (QoS) requirement. In this paper, it is proved that for each prime v ?? 1 (mod 24), there exists a (v, {3, 4}, 1, {2/3, 1/3})-OOC.
The study was conducted to learn remote sensing information extraction in alpine wetland in Maqu, Gansu. The first principle component obtained by utilizing TM multispectral data, digital elevation data, GIMMS NDVIand principal component analysis (PCA) was regarded as the classification character. The decision tree module for wetland information extraction was built through analyzing data with spatial...
Paraphrase recognition is the basic of paraphrase researches. However, most of the existing researches mainly focus on the acquirement of paraphrases from a certain text corpus, or their methods are restricted to certain conditions. There is not a method that can decide whether two sentences are paraphrases generally. This paper presents a combination of rule and supervised learning method to recognize...
In this work, two HTS YBCO rf SQUIDs are used to form a gradiometer without electronic subtraction and digital data processing is applied to cancel the environmental noise. With healthy volunteers as measuring subjects, MCG recordings of various signal-to-noise-ratio SNR are obtained under different shielding conditions in environments of different noise components and characteristics. To extract...
A digital watermarking method for color image in wavelet domain is proposed. The watermarking information which include a section of template information, is embedded into low-frequency coefficients of Y component in YUV color space. This section of template information defines a kind of relation between the low-frequency coefficients corresponding to the four sub-images obtained by down-sampling...
Road extraction research has always been an active research on automatic identification of remote sensing images. In this paper, improving the traditional algorithm, the author presents a new method which uses multi-weighted terms to judge the road edges, makes full use of the physical characteristics of the road, and makes the context of road edge pixels as a judgment, in order to recognize the edge...
Worm attacks have been major security threats to the Internet. Detecting worms, especially new, unseen worms, is still a challenging problem. In this paper, we propose a new worm detection approach based on mining dynamic program executions. This approach captures dynamic program behavior to provide accurate and efficient detection against both seen and unseen worms. In particular, we execute a large...
To address the issues that user evaluation data is extremely sparse, the user-accessing matrix based on Web log mining is established, which takes the frequencies of user accessing, browsing time and the length of the pages into consideration. Furthermore, a novel collaborative filtering algorithm based on Web page rating prediction is proposed. This method predicts Web page ratings that users have...
