Detailed Description
A Softmax layer in a network definition.
This layer applies a per-channel softmax to its input.
The output size is the same as the input size.
- Warning
- Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.

Set the axis along which softmax is computed. Currently, only one axis can be set.
The axis is specified by setting the bit corresponding to the axis to 1. For example, consider an NCHW tensor as input (three non-batch dimensions).
In implicit mode : Bit 0 corresponds to the C dimension boolean. Bit 1 corresponds to the H dimension boolean. Bit 2 corresponds to the W dimension boolean. By default, softmax is performed on the axis which is the number of axes minus three. It is 0 if there are fewer than 3 non-batch axes. For example, if the input is NCHW, the default axis is C. If the input is NHW, then the default axis is H.
In explicit mode : Bit 0 corresponds to the N dimension boolean. Bit 1 corresponds to the C dimension boolean. Bit 2 corresponds to the H dimension boolean. Bit 3 corresponds to the W dimension boolean. By default, softmax is performed on the axis which is the number of axes minus three. It is 0 if there are fewer than 3 axes. For example, if the input is NCHW, the default axis is C. If the input is NHW, then the default axis is N.
For example, to perform softmax on axis R of a NPQRCHW input, set bit 2 with implicit batch mode, set bit 3 with explicit batch mode.
- Parameters
-
axes The axis along which softmax is computed. Here axes is a bitmap. For example, when doing softmax along axis 0, bit 0 is set to 1, axes = 1 << axis = 1.
