This study suggests a dynamical implementation of this hypothesis using recurrent oscillatory self-organizing map of the feature space of such streams. The mapping allows the system to assign identity and class-membership to each stream point, represented by a locus on a two-dimensional map. The model is shown to detect periodicities of various regular and behavior-originated, single- and multi-channel wave patterns, and to reproduce such signals, relying solely on the oscillating activation of the units.<\/em><\/p>\n<p><strong>MaxMSP Jitter version of ROSOM: <a href=\"http:\/\/robin.meier.free.fr\/neurob\/jit-rosom-080804.zip\">jit.rosom<\/a><\/strong><\/p>\n<p><a href=\"http:\/\/robin.meier.free.fr\/rosom_context_acti.mp4\">video<\/a> of the rosom&#8217;s context weights during learning<br \/>\n<a href=\"http:\/\/robin.meier.free.fr\/rosom_acti_learned_zigzag.mp4\">video<\/a> of the rosom&#8217;s content weights as they have learned a zig-zag movement (cf help patch)<br \/>\n<a href=\"http:\/\/robin.meier.free.fr\/rosom_recall.mp4\">video<\/a> of the rosom&#8217;s content weights during a (blind) recall of the learned cycle<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Period detection and representation by recurrent oscillatory self-organizing map by Mauri Kaipainen and Tommi Ilmonen Abstract: Whether or not periodicity is a property of the environment, for a cognitive system a period is always a dynamical mental construct.
