WebOnce representative points are available, the criteria for neighbourhood can be extended from just contiguity to include graph measures, distance thresholds, and $k$-nearest neighbours. The most direct graph representation of neighbours is to make a Delaunay triangulation of the points, shown in the first panel in the figure.

• Markov blanket • Moore neighbourhood • Von Neumann neighbourhood • Second neighborhood problem WebThe graph that is constructed in this way is called the randomized neighborhood graph. Standard arguments from probability theory imply that each point has expected out-degree O(log n). Hence, the expected size of the data structure is bounded by O(n log n). The data structure can be built in O(n 2) time in a straightforward way.
