Large margin metric learning learns the optimal Mahalanobis distance for classification problem based on the margin maximization principle. The loss function in this method is defined for triples of instances, called triplet. However, the number of triplets can be huge even for small datasets and it causes large computational cost for the optimization. In this paper, we propose safe triplet screening by which unnecessary triplets can be safely eliminated before or during learning without loosing the optimality. We analyze several types of screening rules derived by considering a region (bound) containing the optimal solution, and evaluate effectiveness of the proposed method by experiments on several benchmark datasets. |
