The Softmax Function

In the next video, we‘ll learn about the softmax function, which is the equivalent of the sigmoid activation function, but when the problem has 3 or more classes.

 

 

 

import numpy as np

def softmax(L):
    expL = np.exp(L)
    sumExpL = sum(expL)
    result = []
    for i in expL:
      result.append(i*1.0/sumExpL)

    return result
