How to replace the default MSE performance function in train function of deep learning with other performance function I can design?

Hi,

When I use the "train" function for a deep learning net training, the default performance function is MSE. Can I replace it with other performance functions I can manually design?

"net.performFcn" property of Neural Network Object defines the function used to measure the network's performance. The performance function is used to calculate network performance during training whenever train is called.

[net,tr] = train(NET,P,T,Pi,Ai) For a list of functions, type help nnperformance.

Hi, Faiz,

Thank you so much! However，there are still only limited options for performance functions. And, I still do not know how to design my own new one. Can you show an example? Thanks a lot.
