526 Analog Sigmoid
526 : Analog Sigmoid
- Author: aleena
- Description: Activation functions for neuromorphic computing
- GitHub repository
- Clock: 0 Hz
How it works
ReLu and sigmoid activation functions are included
How to test
For ReLu:The output is same as the input value if it is positive and zero otherwise. For Sigmoid:Used for binary classification and predict the probability as output.
External hardware
A voltage source at analog pin 1 and analog pin 4 which is an output of an ANN
