When p = q = 2 for the , norm, it is called the Frobenius norm or the Hilbert–Schmidt norm, though the latter term is used more frequently in the context of operators on (possibly infinite-dimensional ... These norms treat an matrix as a vector of size , and use one of the familiar vector norms. For example, using the p-norm for vectors, p ≥ 1, we get: This is a different norm from the induced p-norm (see above) and the Schatten p-norm (see below), but the notation is the same. The special case p = 2 is the Frobenius norm, and p = ∞ yields the maximum norm.

WebSep 5, 2024 · Squaring the L2 norm calculated above will give us the L2 norm. It is convenient because it removes the square root and we end up with the simple sum of every squared value of the vector. The squared Euclidean norm is widely used in machine learning partly because it can be calculated with the vector operation x ᵀ x. WebMenu is for informational purposes only.
