Recognizing patient samples with gene expression profiles is used to cancer diagnosis and therapy. In the high dimensional, huge redundant and noisy gene expression data the cancerogenic factor's locality is studied. Using gene feature transformation a relative space to a cancer is built and a least spread space with least energy to the cancer is extracted. And it is proven that the cancer is able to be recognized in the least spread space and a cancer classification with least spread space (CCLSS) is proposed. In the Leukemia dataset and Colon dataset the correlation between the recognition rate and the rank of least spread space is explored, then the optimal least spread spaces to AML/ALL and to tumor colon tissue (TCT)/normal colon tissue (NCT) are extracted. At last using LOOCV the experiments with different classification algorithms are conducted and the results show CCLSS makes better precision than traditional classification algorithms.
