ReLU Derivative
EasyMachine LearningMathArray
Description
Given an array of pre-activation values, return the derivative of ReLU at each value: 1 where the input is positive and 0 otherwise.
Examples
Input:
[1,-1,0,2]Output:
[1,0,0,1]Explanation:
ReLU has a slope of one wherever the input is positive and a slope of zero everywhere else, including at and below zero.
Input:
[-5,5]Output:
[0,1]Explanation:
ReLU has a slope of one wherever the input is positive and a slope of zero everywhere else, including at and below zero.
Input:
[0]Output:
[0]Explanation:
ReLU has a slope of one wherever the input is positive and a slope of zero everywhere else, including at and below zero.
