I am trying to code functions that will put a variable or number through the sigmoid function and another one for the step function.

Sigmoid is 1/(1 + e ^ x) You need to use return lest you are saving the values directly. E should be exp() and power should be pow( input, power).

Yes Can you please show your entire code and tell us what the problem is? Usually we don’t post solutions

I don’t know how to code it, so I am just looking for a general idea to start.

Thanks for your replies, I did search the internet, but I never really found a way to put variables in it, I probably didn’t look hard enough. @paulgoux should I do this?: float e = exp(1.0) 1/(1+pow(e, x); I don’t know what x should be, is it the input? I want the sigmoid to go from 0 to 1, bec…

X is the variable you are testing the sigmoid should return a value based on that calculation

Ok so x is the input. One more request @paulgoux , I would like the same function just the other way around, in your equation negative numbers get closer to 1, and positive numbers get closer to 0. Is there a way to make negative numbers closer to 0, and positive numbers closer to 1.

Just do 1 - your sigmoid function

Never mind, I got it, Thanks for your help everyone :smiley:.

Hello, can you please post your solution/ entire sketch?
