NeuralNetwork.backward

NeuralNetwork.backward(input_data, weights)[исходный код]

Backward pass of the network.

Параметры
  • input_data – input data of the shape (num_inputs). In case of a single scalar input it is directly cast to and interpreted like a one-element array.

  • weights – trainable weights of the shape (num_weights). In case of a single scalar weight

  • array. (it is directly cast to and interpreted like a one-element) –

Результат

The result of the neural network of the backward pass, i.e., a tuple with the gradients for input and weights of shape (output_shape, num_input) and (output_shape, num_weights), respectively.
