Mathematical Formulation

yc=eZc∑d=1CeZd

where C is a size of tensor along axis dimension.

Inputs:

  • 1: Input tensor with enough number of dimension to be compatible with axis attribute. Required.

Outputs:

  • 1: The resulting tensor of the same shape and type as input tensor.

Example

<layer ... type="SoftMax" ... >
    <data axis="1" />
    <input> ... </input>
    <output> ... </output>
</layer>
