THE QUESTION OF REPRESENTATIONS Now if one is to take seriously neural networks as cognitive models, the question of representations becomes inescapable. (ucsd.edu)
Indeed most cognitive models consist essentially in representing a task domain and devising appropriate operations on the representations. (ucsd.edu)
Conversely this has encouraged other theoreticians to defend an eliminativist position, where representations would not be needed for cognitive modeling (Churchland 86). (ucsd.edu)
And those representations have to be compared with classical symbols, if only because a large majority so far of cognitive models has been designed with symbolic representations, whose expressive power is indeed hard to match (Memmi 90). (ucsd.edu)
