If you consider a linear map between vector spaces (such as the Jacobian) J: u ∈ U → v ∈ V, the elements v = J u have to agree in shape with the matrix-vector definition: the components of v are the inner products of the rows of J with u. In e.g. linear regression, the (scalar in this case) output space is a weighted combination ...

WebJun 5, 2024 · We can find the derivative of a smooth map on directly, since it is an open subset of a vector space. Let be a matrix; then the derivative at the identity evaluated at is is a polynomial in , and the number we’re looking for is the coefficient of the term. We have Just to get a concrete idea of what this expands to, let’s look when . Then When , A linear transformation between topological vector spaces, for example normed spaces, may be continuous. If its domain and codomain are the same, it will then be a continuous linear operator. A linear operator on a normed linear space is continuous if and only if it is bounded, for example, when the domain is finite-dimensional. An infinite-dimensional domain may have discontinuous linear operators.
