More specifically, you extract a single feature vector from set X and then apply K-means clustering to the whole X & Y set.
ps: Be careful not to confuse k-means with kNN (k-nearest neighbors). You are able to apply only unsupervised learning methods. | 2 | 1 | 1 | I have a collection X of documents, all of which are of class A (the only class in which I'm interested or know anything about).
