Computing the gradient of the criterion with respect to its own input.
Computing the gradient of the criterion with respect to its own input. This is returned in gradInput. Also, the gradInput state variable is updated accordingly.

gradient of input
Computes the loss using input and objective function.
Computes the loss using input and objective function. This function returns the result which is stored in the output field.

the loss of the criterion
The criterion that takes two modules to transform input and target, and take one criterion to compute the loss with the transformed input and target.
This criterion can be used to construct complex criterion. For example, the
inputTransformerandtargetTransformercan be pre-trained CNN networks, and we can use the networks' output to calculate the high-level feature reconstruction loss, which is commonly used in areas like neural style transfer (https://arxiv.org/abs/1508.06576), texture synthesis (https://arxiv.org/abs/1505.07376), .etc.The numeric type in the criterion, usually which are Float or Double
