From: Peter de Jong <DEJONG%OZ.AI.MIT.EDU@XX.LCS.MIT.EDU> Subject: Cognitive Science Calendar [Extract - Ed] [Forwarded from the IRList digest.] DYNAMICAL CONNECTIONISM Elie Bienenstock Universite de Paris-Sud Wednesday, 11 November E25-406, 12:00 In connectionist models, computation is usually carried out in a space of activity levels, the connectivity state being frozen. in contrast, dynamical connectionist models manipulate connectivity states. For instance, they can solve various graph matching problems. They also have the typical associative memory and error-correcting properties of usual connectionist models. Applications include invariant pattern recognition; dynamical connectionist models are able to generalize over transformation groups rather than just Hamming distance. It is proposed that these principles underlie much of brain function; fast- modifying synapses and high-resolution temporal correlations may embody the dynamical links used in this new connectionist approach.
