Nll_loss
Description
The negative log likelihood loss.
Usage
nnf_nll_loss(
input,
target,
weight = NULL,
ignore_index = -100,
reduction = "mean"
)
Arguments
input |
|
target |
|
weight |
(Tensor, optional) a manual rescaling weight given to each class.
If given, has to be a Tensor of size |
ignore_index |
(int, optional) Specifies a target value that is ignored and does not contribute to the input gradient. |
reduction |
(string, optional) – Specifies the reduction to apply to the output: 'none' | 'mean' | 'sum'. 'none': no reduction will be applied, 'mean': the sum of the output will be divided by the number of elements in the output, 'sum': the output will be summed. Default: 'mean' |
