coreset

plural coresets

1. computationalA small set of points that approximates the shape of a larger point set, in the sense that applying some geometric measure to the two sets (such as their minimum bounding box volume) results in approximately equal numbers.

   This coreset based learning approach can be applied for both real-time learning of small, varied data and fast learning of big data..
