Machine Learning: The Sigmoid Function

Question

Calculate Node Output.

Task
You are given the values for w1, w2, b, x1 and x2 and you must compute the output for the node. Use the sigmoid as the activation function.

Input Format
w1, w2, b, x1 and x2 on one line separated by spaces

Output Format
Float rounded to 4 decimal places

Sample Input
0 1 2 1 2

Sample Output
0.9820

I'm having trouble, and the due date is today, which I think is stupid, since these things take WAY longer to learn than usual.

If anyone can give the answer to me, I would be glad. Thanks.

Answer 1

w1, w2, b, x1, x2 = [float(x) for x in input().split()]
import math
output = w1*x1 + w2*x2 + b
output = round(1/(1 + math.exp(output*-1)), 4)
print(output)

Answer 2

import math

w1, w2, b, x1, x2 = [float(x) for x in input().split()]

r = w1*x1 + w2*x2 + b

def sigmoid(r):
sig = 1 / (1+math.exp(-r))
print(round(sig, 4))

sigmoid(r)

Answer 3

ANS :

w1, w2, b, x1, x2 = [float(x) for x in input().split()]
import math
y=(w1*x1)+(w2*x2)+b
z = math.exp(-y)
sig = 1 / (1 + z)
sig = round(sig,4)
print(sig)

Answer 4

Siavosh sanoodi please see my code above

Answer 5

Show. Your. Attempt.

Answer 6

Value =( W1*X1 + W2 * X2 ) + b
Then put value in sigmoid function

Sigmoid = 1/(1+(e**-value)) -> import e from math (from math import e)

Answer 8

It says that the result should be 0.982

Answer 9

w1, w2, b, x1, x2 = [float(x) for x in input().split()]
import math
output = w1*x1 + w2*x2 + b
output = round(1/(1 + math.exp(output*-1)), 4)
print(output)

Answer 10

My solution
import math
w1, w2, b, x1, x2 = [float(x) for x in input().split()]
def sigmoid(out):
sigmoids=round(1/(1+math.exp(out*-1)),4)
return sigmoids

output=w1*x1+w2*x2+b;
print(sigmoid(output))
