Only Numpy Implementing Different combination of L1 /L2 norm
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 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

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.

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.
