WebApr 13, 2024 · $\begingroup$ @composer Using the histogram or even a kernel smooth of the data is usually not an "easy" way to cluster. If you want to go this way, you need to fit a finite mixture model. If you just want what a casual view of a histogram might suggest, use K-means (also known as Jenks' method, popular among cartographers). $\endgroup$ – WebSuch data, which can be expressed as concepts, are modeled by symbolic objects described by multivalued variables. In the present paper we present a new distance, based on the Wasserstein metric, in order to cluster a set of data described by distributions with finite continue support, or, as called in SDA, by “histograms”.
