Measuring non-trivial compositionality in emergent communication

Understand

Compositionality is an important explanatory target in emergent communication and language evolution.

• The vast majority of computational models of communication account for the emergence of only a very basic form of compositionality: trivial compositionality.
• A compositional protocol is trivially compositional if the meaning of a complex signal (e.g.
• blue circle) boils down to the intersection of meanings of its constituents (e.g.
