Ptn NLL Loss

A model to compute the negative log likelihood (NLL) loss.

Unlike Ptn Cross Entropy which takes input in logits, input to this nodes needs to be in log-probabilities.

Args:  
    reduction: (str): Reduction method.  
                      `none`: no reduction will be applied done.   
                      `mean`: computes the mean.  
                      `sum`: computes the sum.
