A regression apparatus10 that optimizes a joint regression and clustering criteria includes a train classifier unit and an acquire clustering result unit. The train classifier unit trains a classifier with a weight vector or a weight matrix, using labeled training data, a similarity of features, a loss function characterizing regression quality, and a penalty encouraging the similarity of features, wherein a strength of the penalty is proportional to the similarity of features. The acquire clustering result unit an acquire clustering result unit that, using the trained classifier, to identify feature clusters by grouping the features which regression weight is equal.
