LogSoftmax

Description

The operator computes the log of softmax values for the given input : LogSoftmax(input, axis) = Log(Softmax(input, axis=axis))
The β€œaxis” attribute indicates the dimension along which LogSoftmax will be performed. The output tensor has the same shape and contains the LogSoftmax values of the corresponding input.

 

Input parameters

 

specified_outputs_name :Β array, this parameter lets you manually assign custom names to the output tensors of a node.
Β input (heterogeneous) – T : object, the input tensor of rank >= axis.

Β Parameters :Β cluster,

Β axis :Β integer, describes the dimension LogSoftmax will be performed on. Negative value means counting dimensions from the back. Accepted range is [-r, r-1] where r = rank(input).
Default value β€œ0”.
Β training?Β :Β boolean, whether the layer is in training mode (can store data for backward).
Default value β€œTrue”.
Β lda coeff :Β float, defines the coefficient by which the loss derivative will be multiplied before being sent to the previous layer (since during the backward run we go backwards).
Default value β€œ1”.

Β name (optional) :Β string, name of the node.

Output parameters

 

Β output (heterogeneous) – T : object, the output values with the same shape as the input tensor.

Type Constraints

T in (tensor(bfloat16),Β tensor(double),Β tensor(float),Β tensor(float16)) : Constrain input and output types to float tensors.
