euclidean distance formula in k means clustering

PDF	11 Clustering Distance Methods and Ordination Proceed through the list of items assigning an item to the cluster whose centroid (mean) is nearest Distance is usually computed using Euclidean distance

What is the distance formula used in k-means clustering?
Calculate squared euclidean distance between all data points to the centroids AB, CD.
For example distance between A(2,3) and AB (4,2) can be given by s = (2–4)² + (3–2)². 4.
If we observe in the fig, the highlighted distance between (A, CD) is 4 and is less compared to (AB, A) which is 5.
Why do we use Euclidean distance in Kmeans?
Euclidean space is about euclidean distances.
Non-Euclidean distances will generally not span Euclidean space.
That's why K-Means is for Euclidean distances only.
But a Euclidean distance between two data points can be represented in a number of alternative ways.
What Is Euclidean Distance Formula? The Euclidean distance formula is used to find the distance between two points on a plane.
This formula says the distance between two points (x1 1 , y1 1 ) and (x2 2 , y2 2 ) is d = √[(x₂ – x₁)² + (y₂ – y₁)²].

What is the Euclidean distance formula for clustering?

ˆ Euclidean distance: d(x,y) = √(x − y)/(x − y). of the distinct groups, these sample quantities cannot be computed.
For this reason, Euclidean distance is often preferred for clustering. the “city-block” distance between two points in p dimensions.

For example distance between A(2,3) and AB (4,2) can be given by s = (2–4)² + (3–2)². A is very near to CD than AB. 4. If we observe in the fig, Autres questions
