            DEFAULT COMBINATIONS

Regression, curve-fitting

      FITNET AND MEAN-SQUARE-ERROR (MSE)

Time-series

      NARXNET AND MEAN-SQUARE-ERROR (MSE)

Pattern Recognition and Classification

       PATTERNNET AND CROSSENTROPY

Hope this helps,

Thank you for formally accepting my answer

The default cost function is Cross Entropy, if am not wrong.

You can check doc patternnet to get more details
