WebJun 9, 2024 · Within Machine Learning applications, the derivative of the Squared L2 Norm is easier to compute and store. The derivate of an element in the Squared L2 Norm requires the element itself. However, in the case of the L2 Norm, the entire vector is needed. Max Norm (or L-∞ Norm): 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.
derivatives - Differentiate the norm of a function
Web$\begingroup$ @PeterK., user153245: That question came out of interest about the background of the original question; I'm very well aware the needs to find a derivate of some norm, metric etc, but usually, when questions like OP's are asked, there's a whole interesting problem to solve behind that :) $\endgroup$ – WebThe derivative of a function represents its a rate of change (or the slope at a point on the graph). What is the derivative of zero? The derivative of a constant is equal to zero, hence the derivative of zero is zero. What does the third derivative tell you? The third derivative is the rate at which the second derivative is changing. is af a disability
