我正在尝试将随机阈值建模为权重，阈值应该有助于减少误差，权重不是随机的，它们是 1。可以更改阈值以使误差为 0？

import numpy as np

# input dataset
X = np.array([[0, 0],
              [0, 1],
              [1, 0],
              [1, 1]])

# output dataset
y = np.array([[0, 0, 0, 1]]).T

syn0 = np.zeros((2, 1)) + 1


threshold = np.random.random_integers(-5, 5)

# forward propagation
l0 = X
l1 = np.dot(l0, syn0)

# how much did we miss?
l1_error = y - l1
print(l1_error)

这是我到目前为止..！
