Dear all, I tried to run a program that I found on the internet but it was not possible because it presented an error. Here you can see the program lines:
import numpy as np
def sigmoid(x):
# Our activation function: f(x) = 1 / (1 + e^(-x))
return 1 / (1 + np.exp(-x))
class Neuron:
def __init__(self, weights, bias):
self.weights = weights
self.bias = bias
def feedforward(self, inputs):
# Weight inputs, add bias, then use the activation function
total = np.dot(self.weights, inputs) + self.bias
return sigmoid(total)
weights = np.array([0, 1]) # w1 = 0, w2 = 1
bias = 4 # b = 4
n = Neuron(weights, bias)
x = np.array([2, 3]) # x1 = 2, x2 = 3
print(n.feedforward(x)) # 0.9990889488055994---------------------------------------------------------------------------Error:AttributeError Traceback (most recent call last)
