Construction¶

softmax_backward()

Default constructor. Produces an empty object.

softmax_backward(const primitive_desc& pd)

Constructs a softmax backward propagation primitive.

Parameters:

pd	Primitive descriptor for a softmax backward propagation primitive.

softmax_backward(
    const primitive_desc& pd,
    const std::vector<uint8_t>& cache_blob
    )

Constructs a softmax backward propagation primitive from a cache blob.
