init(function:i_desc:o_desc:reduction:label_smooth:)
Returns a new softmax cross entropy loss layer parameters structure from the specified parameters.
Declaration
init(function: BNNSLossFunction, i_desc: BNNSNDArrayDescriptor, o_desc: BNNSNDArrayDescriptor, reduction: BNNSLossReductionFunction, label_smooth: Float)Parameters
- function:
The function that’s used to compute loss.
- i_desc:
The descriptor of the input.
- o_desc:
The descriptor of the output.
- reduction:
The function that’s used to reduce the computed loss.
- label_smooth:
A value that defines the smoothing that the loss function applies to the labels.
