I understand the principles of LMNN (Large-Margin Nearest Neighbor) classification very well, but not all that well Weinberger's pseudo-code for its implementation. Can anyone simply (but thoroughly) describe a simple implementation of the LMNN algorithm (i.e. calculation of the Mahalanobis matrix - M), or direct me to such a document?

Thanks much.
