Principal component analysis and k-means clustering. We plot the first three principal components of the space of the four log transformed features TC1, c-KIT, miR-146, and miR-222 in the context of classifying malignant vs benign. The data points in the plots on the left are labeled according to their condition (“Malignant vs Benign”). The plots on the right show the clusters identified by the unsupervised analysis performed via k-means clustering. We can see that the separation induced by the conditions “Malignant vs Benign” approximately reproduces/reflects the intrinsic grouped structure of the data
