WebAug 1, 2024 · Solution 2. Let X = ( x i j) i j and similarly for the other matrices. We are trying to differentiate. ‖ X W − Y ‖ 2 = ∑ i, j ( x i k w k j − y i j) 2 ( ⋆) with respect to W. The result will be a matrix whose ( i, j) entry is the derivative of ( ⋆) with respect to the variable w i j. So think of ( i, j) as being fixed now. WebThe derivative is an important tool in calculus that represents an infinitesimal change in a function with respect to one of its variables. Given a function f (x) f ( x), there are …
