FAST METHODS OF LEARNING DISTANCE METRIC FOR CLASSIFICATION AND RETRIEVAL |
摘要 |
A nearest-neighbor-based distance metric learning process includes applying an exponential-based loss function to provide a smooth objective; and determining an objective and a gradient of both hinge-based and exponential-based loss function in a quadratic time of the number of instances using a computer.
