Seeking a simple but effective classifier is exciting and meaningful in both machine leaning and data mining. As usual, simplicity and high performance are two sides of a same coin. Our aim is to explore an easy-to-use classifier without losing its effecti...
A Study of Laplacian Spectra of Graph for Subgraph Queries
Found in: Data Mining, IEEE International Conference on
By Lei Zhu,Qinbao Song
Issue Date:December 2011
pp. 1272-1277
The spectrum of graph has been widely used in graph mining to extract graph topological information. It has also been employed as a characteristic of graph to check the sub graph isomorphism testing since it is an invariant of a graph. However, the spectru...
A General Software Defect-Proneness Prediction Framework
Found in: IEEE Transactions on Software Engineering
By Qinbao Song, Zihan Jia, Martin Shepperd, Shi Ying, Jin Liu
Issue Date:May 2011
pp. 356-370
BACKGROUND—Predicting defect-prone software components is an economically important activity and so has received a good deal of attention. However, making sense of the many, and sometimes seemingly inconsistent, results is difficult. OBJECTIVE—We propose a...
k-NN Numeric Prediction Using Bagging and Instance-relevant Combination
Found in: Data, Privacy, and E-Commerce, International Symposium on
By Liang He, Qinbao Song, Junyi Shen
Issue Date:September 2010
pp. 3-8
The fixed number of reference neighbors leads to mutable prediction errors and low overall accuracy for various unknown instances, according to existing k-NN methods. To address this problem, a bagging-based k-NN numeric prediction algorithm with attribute...
