Abstract: A generalized CL-stability algorithm proposed in this paper can be used to recognize mislabeled samples and abnormal samples in cancer microarray. The CL-stability is selected as a basic operator in the proposed a lgorithm. The mislabeled samples or abnormal samples are detected depending on the gobal stability of samples. Experimental results show that the generalized CL-stability algorithm is not only better than other existing algorithms, but also used to distinguish mislabeled samples and abnormal samples.
