### Backpropagation for a Linear Layer

cs231n.stanford.edu

During the backward pass through the linear layer, we assume that the derivative @L @Y has already been computed. For example if the linear layer is part of a linear classi er, then the matrix Y gives class scores; these scores are fed to a loss function (such as the softmax or multiclass SVM loss) which computes the scalar loss L and derivative @L

3. TRUE or FALSE: If we have two linear transformations, S and T, both from Rn!Rn, then S T = T S. Solution note: AC = ad+ 1 a+ c d 1 ;CA = 1 a+ c d ad+ 1 : These are not equal in general, so matrix multiplication does not satisfy the commutative law! In particular, linear transformations do not satisfy the commutative law either, so (3) is FALSE.
