centroids
Centers of mass
Centroids are center points of geometric shapes or data clusters.
In geometry, a centroid is the point where a shape would balance perfectly—the center of mass of a triangle, polygon, or three-dimensional object.
In statistics and data science, centroids represent the average position of clustered data points: The algorithm assigns each observation to the nearest centroid.
The singular is centroid.
