10 runs 10-time 5-fold cross-validation for leukemia cancer data. Solid line with black “∗” with legend d.t. is the decision tree method, dashed line with red “⚪” marked “knn-1” means K-nearest neighborhood when K = 1, dash-dot line with blue point marked “knn-5” means K-nearest neighborhood when K = 5, solid line with “+” in cyan labeling “knn-10” is the K-nearest neighborhood when K = 10, solid line with magenta “□” is the usual correlation kernel, diamond yellow line represents the parsimonious correlation kernel, and hexagram green line is the denoised correlation-based kernel.
