Gradient back propagation
WebThe back-propagation algorithm proceeds as follows. Starting from the output layer l → k, we compute the error signal, E l t, a matrix containing the error signals for nodes at layer l E l t = f ′ ( S l t) ⊙ ( Z l t − O l t) where ⊙ means element-wise multiplication. WebBackpropagation adalah suatu metode untuk menghitung gradient descent pada setiap lapisan jaringan neuron dengan menggunakan notasi vektor dan matriks.
