In order to understand the principles behind how humans perform planning, inference, and pragmatics, we aim to develop a parsimonious, interpretable model with few parameters rather than a highly expressive, data-driven model.
following the tradition of Rational Speech Acts (RSA) (Frank and Goodman, 2012; Goodman and Frank, 2016), we will define in this section a mapping from each word to its literal semantics, and rely on the PIP re- currences (which we will describe in Section 4) to provide context-dependence.
