Cognitive Information Processing workshop in Santorini

Professors Simon Haykin and Sergios Theodoridis chaired a workshop on Cognitive Information Processing in Santorini, Greece in June 2008. The keynote speakers included Simon Haykin, José Principe, Ali Sayed, Bernhard Schölkopf, Naftali Tishby and Timo Honkela. There were many interesting, mostly methodological presentations, including some presentations on the special theme of cognitive radio. The term "cognitive" was discussed and it was concluded that it has been used in different ways covering the concept at different levels of detail.

known for his excellent text book on pattern recognition with Koutroumbas.

Naftali Tishby gave an interesting keynote with a focus on the perception-action cycle. Among other things, he considered the topic from the point of view of information bottleneck. There is a predictive channel between the unknown future (channel output) and partially observed past (channel input). An organism links these so that the sensing costs and action value are taken into account.
