... However, in certain cases, this condition would be impossible to satisfy for any combination of a neural network, encoding function and aggregation function. In particular, in first-order logic, the Lowenheim-Skolem theorem states that a knowledge base that admits a model of infinite cardinality has models of arbitrary cardinality Podnieks and Detlovs [2017]. This means that the collection of all models for many knowledge bases in first-order logic is not a set, but a proper class, whereas by definition M N must be a set. ...
