The numerical computation of the Euclidean norm of a vector is perfectly well conditioned with favorite a priori error estimates. Recently there is interest in computing a faithfully rounded approximation which means that there is no other floating-point number between the computed and the true real...
(Lower bound [2]): We first introduce the auxiliary function Σ↦g⊤Σg=:f(Σ):S+n→R+. Since g⊤Σg is the composition of a concave function (i.e., ⋅) and a linear function (i.e., g⊤Σg=⟨Σ,gg⊤⟩), it is thus concave. Let Σi=neiei⊤∈S+n where...

It is a version of the Euclidean distance that was calculated over only some vector elements. Window size was crucial in this setup. The partial distance between ‘a’ and ‘b’ for a window size ‘w’ in an N-dimensional space is: d(a,b)=∑i=1N(asi−bsi)2 where si is in ra...
The inner product on the Euclidean vector space E2 By definition, a Euclidean n-space is the coordinate space ℝn, equipped with the dot product inner product. 〈u_, v_〉 := Sqrt[Dot[u, v]] u = {1, 2}; v = {3, 4}; 〈u, v〉 11 Norm[{1, 2}] == 〈{1, 2}, {1...

The way to solve this problem is to normlize the data and use distance calculation methods IP instead. Openblas uses a special optimization in the implementation of the Eu distance formula, which speeds up the calculation, but slightly affects the weighting of certain dimensions of the vector, ...
