Hi Ahmad,

I understand that you want to know how to compute the validation metrics and plot them. You can achieve this with the help of the `trainingOptions` function.

This function has an input called `Metrics` where predefined metrics can be used. You can also create your own custom metrics for the model.

Here's a code snippet to access the metrics using the `info`.

[netTrained,info] = trainnet(___);
show(info);

Refer the below documentions for better undertanding:

Hope it helps!
