A model for inventing new signals is introduced in the context of sender-receiver games with reinforcement learning. If the invention parameter is set to zero, it reduces to basic Roth-Erev learning applied to acts rather than strategies, as in Argiento et al. (Stoch. Process. Appl. 119:373-390, 2009). If every act is uniformly reinforced in every state it reduces to the Chinese Restaurant Process-also known as the Hoppe-Pólya urn-applied to each act. The dynamics can move players from one signaling game to another during the learning process. Invention helps agents avoid pooling and partial pooling equilibria.
