A generalisation is a statement about a class.

The generalisation applies to instances of that class.

Generalisation and ambiguity

Both ambiguity and generalisation involve one-to-many relationships:

  • Ambiguity: one perception with many possible interpretations
  • Generalisation: one class with many possible instances

The distinction is that the interpretations in a case of ambiguity are mutually independent, whereas the instances in a generalisation are members of some class.

A generalisation assumes some model that explains the class and its membership. Without an understanding of the model, a generalisation may have the appearance of an ambiguity.
