Abstract: The Rational Speech Acts model (RSA) formalizes Gricean reasoning through nested models of speakers and listeners. While this paradigm offers an elegant way to simulate pragmatic behavior in NLP tasks such as image captioning and translation, scaling from simple models to natural language presents several challenges. In particular, I discuss the problem of choosing alternative utterances among an unbounded set of sentences, including work on image captioning and on-going work on translation.
