plottrainstate(tr)

Figure Training State (plottrainstate) contains 3 axes objects. Axes object 1 with title Gradient = 62.2481, at epoch 15, ylabel gradient contains an object of type line. Axes object 2 with title Mu = 0.001, at epoch 15, ylabel mu contains an object of type line. Axes object 3 with title Validation Checks = 6, at epoch 15, xlabel 15 Epochs, ylabel val fail contains a line object which displays its values using only markers.
