Softplus Activation
EasyMachine LearningMathArray
Description
Given an array of numbers, apply the Softplus activation ln(1 + e^x) to each element. Round each result to 4 decimal places.
Examples
Input:
[0,1,-1]Output:
[0.6931,1.3133,0.3133]Explanation:
Softplus is a smooth approximation of ReLU that bends gently through ln(2) at zero and approaches the input for large positive values.
Input:
[2]Output:
[2.1269]Explanation:
Softplus is a smooth approximation of ReLU that bends gently through ln(2) at zero and approaches the input for large positive values.
Input:
[-2,2]Output:
[0.1269,2.1269]Explanation:
Softplus is a smooth approximation of ReLU that bends gently through ln(2) at zero and approaches the input for large positive values.
