Two problems…
lModel looks at what happens to a language that is completely compositional vs. completely holistic
ˇi.e., Lyapunov local stability
ˇNote: same problem for Nowak et. al in Nature
lWhat about partially compositional systems?
lModel assumes
that meaning-space is fixed and provided by
some other evolutionary mechanism
ˇSeems
to run counter to the “spirit” of adaptation through iterated learning
lWhat if the
meaning-space coevolves with the syntactic
system?
