What is the difference between clustering and matching?
For example: There's a pool of four elements and in the one scenario I want to generate pairs. What I do is I measure the distance of each element to each other which yields a 2x2 matrix. Then the matching algorithm finds the two pairings with the lowest or highest weighted sum.
What is a clustering algorithm doing? When I demand a cluster number of two then the result is the same, or not?
