I have the R2017a version of Matlab and Neural Network Toolbox. I would like to implement face-recognition and one of the loss function of the state of the art algorithms is "Triplet loss". How can I implement it in Matlab with the Neural Network Toolbox?
Thanks.

Unfortunately, as of right now there is no way of customizing the loss function when training a neural network in MATLAB. An enhancement request has been submitted for this feature, and our development team will consider it for a future release of MATLAB
