Backpropagation calculates the ____ and propagates it back to earlier layers.
A
value
B
error
C
data
D
None of the above
Explanation: 

Detailed explanation-1: -Answer. Answer: Backpropagation calculates the algorithm and propagates it back to earlier layers.

Detailed explanation-2: -Backward pass at the output layer The error on weight w is calculated by differentiating total error with respect to w.

Detailed explanation-3: -The backpropagation algorithm is an efficient way to compute the error ℓ iteratively using error ℓ+1, so we proceed by computing the error from the last layer L, again, using the chain rule:(20.8)jL=∑k∂Remp∂akL∂akL∂zjL, and, when k≠L, the terms vanish and we obtain:jL=∂Remp∂ajL∂ajL∂zjL=∂Remp∂ajL′(zjL).
