The conference entitled "Condensed Complexity - The Essence of Information Processing and Cognition?" was opened today by FIAS Director Eckhard Elsen. From November 6, 2023 to November 10, 2023, experts from various fields, including neuroscience, physics, molecular and developmental biology, simulation and machine learning as well as quantum computing and sensing, will come together. The aim of the conference is to uncover the common principles that connect these seemingly disparate fields of research and deepen our understanding of knowledge, cognition and information processing.
