Collective Intelligence in Living/Non-Livings Populations


Tuesday, November 22, 2022 - 09:00 to 17:00


C210, Zoom


The purpose of this workshop is to elucidate the phenomena of living (ants, bees, creatures, ...) and non-living (agents within neural nets, web services, ...) populations and to discuss possible theoretical frameworks for them.

The workshop is open to anyone at OIST with an interest in the discussed topics.
