Correct backpropagation in simple perceptron
Given the simple OR gate problem:
or_input = np.array([[0,0], [0,1], [1,0], [1,1]])
or_output = np.array([[0,1,1,1]]).T
If we train a simple single-layered perceptron (without backpropagation), we
or_input = np.array([[0,0], [0,1], [1,0], [1,1]])
or_output = np.array([[0,1,1,1]]).T
