Derivative of the 2 -norm of a multivariate function Ask Question Asked 10 years, 11 months ago Modified 3 months ago Viewed 92k times 33 I've got a function g(x, y) = ‖f(x, y)‖2 and I want to calculate its derivatives with respect to x and y. Using Mathematica, differentiating w.r.t. x gives me f ′ x(x, y)Norm ′ (f(x, y)), where Norm is ‖ ⋅ ‖.

The concept of logarithmic derivative μ [ A] is used in [2], [1] in the theory of ordinary differential equations to obtain new results, e.g., in stability problems, and the results improve those obtained by using the norm ∥ A ∥.

This norm can be defined as the square root of the inner product of a vector with itself. A seminorm satisfies the first two properties of a norm, but may be zero for vectors other than the origin. [1] A vector space with a specified norm is called a normed vector space.

The derivative of a vector-valued function can be understood to be an instantaneous rate of change as well; for example, when the function represents the position of an object at a given point in time, the derivative represents its velocity at that same point in time. We now demonstrate taking the derivative of a vector-valued function.

The Gateaux derivative of k · k at vin direction of uis defined as lim t→0 kv+tuk −kvk t. We say k · k is Gateaux differentiable at 0 6= vif and only if for all u∈ V, lim t→0 kv+tuk−kvk t exists. A concept related to the Gateaux derivative of norm function is the subdifferential set of norm function (see [9]). The subdifferential set

We find an expression for Gateaux derivative of the C∗ -algebra norm. This gives us alternative proofs or generalizations of various known results on the closely related notions of subdifferential sets, smooth points and Birkhoff-James orthogonality for spaces B(H) and Cb(Ω). We also obtain an expression for subdifferential sets of the norm.

The norm is extensively used, for instance, to evaluate the goodness of a model. By the end of this tutorial, you will hopefully have a better intuition of this concept and why it is so valuable in machine learning. We will also see how the derivative of the norm is used to train a machine learning algorithm.

Subject classifications. Let X and Y be Banach spaces and let f:X->Y be a function between them. f is said to be Gâteaux differentiable if there exists an operator T_x:X->Y such that, for all v in X, lim_ (t->0) (f (x+tv)-f (x))/t=T_xv. (1) The operator T_x is called the Gâteaux derivative of f at x. T_x is sometimes assumed to be bounded.

One way to approach this to define x = Array [a, 3]; Then you can take the derivative x = D [x . x, {x}] and you'll get more what you expect. Otherwise it doesn't know what the dimensions of x are (if its a scalar, vector, matrix). - bill s. Apr 11, 2021 at 20:17. Thanks, now it makes sense why, since it might be a matrix.
