SoftMaxGradual approach of a floor below which output can never fall |
 |
Diagram
Information
The output y is obtained as a smooth maximum with regard to the inputs u and u_min:
The following graph shows the results for u_min = 1.0 and k ∈ {10,5,3,2}:

Notes
- The soft maximum is a special case of the generalized f-mean.
