Dirac measure

Summary

The Dirac measure at a point xx gives a set the value 11 if the set contains xx, and the value 00 if not. It is the probability measure of a random quantity that always takes the value xx. The node Dirac measure gives the precise definition.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
