Documentation

Mean Squared Error criterion. Compute the MSE between its inputs and, the targets of its associated DataSet.

The number of target frames in DataSet must correspond to the number of input frames given to this criterion.

Options:
"average frame size" bool divided by the frame size [true]

o MSECriterion(int n_inputs_)
n_inputs_ is the input frame size
