Derivative of product of matrices
Webn, and write out the full derivative in matrix form as shown in (4). The resulting matrix will be baT. 4.2 Derivative of a transposed vector The derivative of a transposed vector w.r.t itself is the identity matrix, but the transpose gets applied to everything after. For example, let f(w) = (y wT x)2 = y2 wT x y y w Tx + w x wT x
