[Solved] Derivative of Euclidean norm (L2 norm) 9to5Science
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.

This notion of derivative is a generalization of the ordinary derivative of a function on the real numbers since the linear maps from to are just multiplication by a real number. In this case, is the function Properties A function differentiable at a point is continuous at that point.

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.

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.
Derivative of norm of function w.r.t realpart of function
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.

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

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.
