First of all, we describe a novel online Logdet divergence based metric learning model which uses triplets as the training constraints.
In Section 2, the proposed online Logdet divergence based metric learning model is presented.
The function [D.sub.ld]() represents Logdet divergence :
There are several advantages when using Logdet divergence to regularize the metric learning process.
