Sum of transpose matrix
Web6 Feb 2024 · The answer is true. Recall that the transpose of a matrix is the sum of its diagonal entries. Also, note that the diagonal entries of the transposed matrix are the same as the original matrix. Putting together these observations yields the equality tr ( A T) = tr ( A). Here is the more formal proof. For A = ( a i j) 1 ≤ i, j ≤ n, the ... Web19 Mar 2024 · That is if you have a sum of inputs in the forward pass, you want to get all the partial derivatives with respect to each of those variables in the backward pass, that is Sum in forward becomes branching in backward If you just multiply by the inverse you are not perfroming those operations. On the other hand,multiplying by the transpose does the trick!
