training algorithm / cost / cross validation

[pywx]

Is there any function that'll show the cost of the neural network on a training sample? Or perhaps do the training examples return the residue of the dataset? I ask this because i wish to make sure i'm not overfitting or underfitting with cross-validation. Thanks!
