For a clustering example, suppose this data is to be clustered. Where euclidean distance is the distance metric. In mathematics the Euclidean distance or Euclidean metric is the ordinary distance between the two points that one would measure with a ruler, which can be proven by repeated application of the Pythagorean theorem. ... In mathematics a metric or distance is a function which assigns a distance to elements of a set. ...
