Bаckprоpаgаtiоn. Indicate whether each оf the following statements is True or False (1 pt each). (a) Backpropagation relies on repeated application of the chain rule to compute gradients. [a] (b) In backpropagation, gradients are propagated from the input layer to the output layer. [b] (c) In Pytorch, the purpose of calling optimizer.zero_grad() in a training loop is to retain and accumulate the gradients from the previous backward pass. [c] (d) The softmax function is differentiable and thus compatible with backpropagation. [d]
