Link prediction plays an important role in complex network analysis. It is to predict the existence of an unknown link or a future link in a network. Classical methods for link prediction evaluate the similarity of vertices based on common neighbors, and denote that every common neighbor makes equal contribution to the connection likelihood. However, common neighbors may play different roles depending...
Hydrocracking process is a complex long-running industrial process. The change of inlet conditions will result in fluctuation of operating parameters and change of running state. It is necessary to classify the inlet conditions to detect the change of raw materials timely, so that the subsequent global operation conditions can be analyzed. However, sampling analysis of the quality indexes of raw oil...
This paper presents an aerial image parsing approach. Firstly, scene categories of aerial image is extracted based on global feature-Spatial Envelope in the top-down step; secondly, the candidate proposals of object categories is classified in bottom-up step; finally, the bottom-up proposals are verified by top-down cues, and the parsing graph of the whole aerial image is obtained. The test on the...
In response to the roller bearing fault of the engineering vehicle, the excellent characteristics of time-frequency of wavelet packet is used to decompose the fault signal. Then we extract the necessary of the fault signals. Finally, we carry out the recognition of fault types using multi-class support vector machine and dynamic clustering algorithm brought forward in the paper. It is such a algorithm...
Essence of software testing is to choose a representative value (known as test case) from the input to perform the programs under test. The actual results of the programs will be checked to verify the consistency with the expected ones. If the results are different, it should take some correction and adjustment correspondingly. The existing method for test suite generation is mainly based on the test...
