Rectified linear unit function with unit derivatives.

Share:

Description

The function calculates the activation of the units and returns a list, in which the first entry is the rectified linear activation of the units and the second entry is the derivative of the transfer function.

Usage

1

Arguments

input

Input for the activation function.

...

Additional parameters, not used.

Value

A list with the rectified linear activation in the first entry and the derivative of the activation in the second entry.
