the Euclidean distance or Euclidean metric is the "ordinary" distance between two points that one would measure with a ruler, and is given by the Pythagorean formula.

In mathematics, the Euclidean distance or Euclidean metric is the "ordinary" distance between two points that one would measure with a ruler, and is given by the Pythagorean formula. By using this formula as distance, Euclidean space (or even any inner product space) becomes a metric space. The associated norm is called the Euclidean norm.

Why tsne method use Euclidean distance to compute the similarities in high dimensional data?

I have tried other distance metrics like chebychev distance or Manhatten distance and so on, which are all implemented in tsne in Matlab. Some of them achieve the same good performance as Euclidean distance metric. So I have some questions about…
