Modelling emergence with
exemplar-based iterated learning
Viktor Trón
The idea behind emergentist models is that language structure is shaped
by use. Iterated learning focuses on the learner as the main
bottleneck in language transmission and queries to what extent the
biases of cognition explain structural generalizations in a particular
linguistic domain.
This talk describes a general dynamic exemplar-based model applied to a
restricted domain of Hungarian morphology. The agent performing
iterated learning is an exemplar-based model of linguistic
categorization. Simulations in this model start from a dataset and let
it undergo a series of transformations as it is learned and reproduced
iteratively. Assessing the dynamics of this process helps us test
hypotheses about directions of change and about the link between model
properties and regularity in the data.
