Norm and distance
Web11 de ago. de 2016 · Finally let me note that what is the default norm is a matter of opinion to some extend: For example J.E. Gentle's "Matrix Algebra - Theory, Computations, and Applications in Statistics" literally has a chapter (3.9.2) named: "The Frobenius Norm - The “Usual” Norm"; so clearly the spectral norm is not the default norm for all parties ... Web28 de jun. de 2024 · Euclidean Distance = sum for i to N (v1 [i] — v2 [i])². The Euclidean is often the “default” distance used in e.g., K-nearest neighbors (classification) or K-means (clustering) to find the “k closest points” of a particular sample point. Another prominent example is hierarchical clustering, agglomerative clustering (complete and ...

WebThe $2$-norm is the usual notion of straight-line distance, or distance ‘as the crow flies’: it’s the length of a straight line segment joining the two points. The $1$-norm gives the distance if you can move only parallel to the axes, as if you were going from one intersection to another in a city whose streets run either north-south or east-west.
