Domain Driven Two-Phase Feature Selection Method Based on Bhattacharyya Distance and Kernel Distance Measurements
Lyon, France

ISBN: 978-0-7695-4513-4
This paper proposes a two-phase feature selection method specific for bioinformatics domain from classification perspective in data mining. In the first phase, Bhattacharyya distance measurement is used for filtering the majority of irrelevant genes. Upon the basis, we apply floating sequential search method (FSSM) to further select informative gene set using kernel distance as measurement of class separability. The verification of colon tissue dataset using support vector machines (SVMs) proves that informative gene set selected by our method is acceptable for disease identification.
