Couldn't get desired output from Adaptive linear neuron implementation #68

Hi, I was trying out one of the example in Chapter2, under title: Implementing an adaptive linear neuron in Python (Link to notebook). The problem is when I plot decision boundaries, whole area is shown red.

When I change output = self.activation(X) to output = self.predict(X)inside fit function, the problem seems to be gone.

Is there an issue with the code or the code is correct and I made some other mistake while implementing?

Thanks Sohaib

I guess Your code is correct with proper decision boundary b/w iris flowers with proper explanation.
