Question

Backpropagation calculates the ………and propagates it back to earlier layers.

Answer 1

Answer:

Backpropagation calculates the algorithm and propagates it back to earlier layers.

Answer 2

Explanation:

Backpropagation Algorithm

Set a(1) = X; for the training examples.

Perform forward propagation and compute a(l) for the other layers (l = 2… ...

Use y and compute the delta value for the last layer δ(L) = h(x) — y.

Compute the δ(l) values backwards for each layer (described in “Math behind Backpropagation” section)
