SoftMax¶
Versioned name : SoftMax-1
Category : Activation function
Short description : Reference
Detailed description : Reference
Attributes
axis
Description : axis represents the axis of which the SoftMax is calculated. axis equal 1 is a default value.
Range of values : positive integer value
Type : int
Default value : 1
Required : no
Mathematical Formulation
\[y_{c} = \frac{e^{Z_{c}}}{\sum_{d=1}^{C}e^{Z_{d}}}\]
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>
