Workshop: Information-Theoretic Principles in Cognitive Systems
Abstract
I will discuss how error and subjectivity and the universal collective property of biological systems shape computation and micro-macro relationships in information processing systems. I will introduce three principles of collective computation: downward causation through coarse-graining, hourglass emergence, and a preliminary, information theoretic concept called channel switching that my collaborators and I are developing to formalize the transition from micro-macro causality to macro-macro causality.

Jessica Flack
Jessica Flack is a professor at the Santa Fe Institute, Director of SFI's Collective Computation Group and a Chief Editor at Collective Intelligence. Flack considers herself to be a computational Platonist who is interested in the foundations of computation in nature, the origins of biological space and timescales, and micro-macro maps in information processing systems. Flack works across levels of biological organization from cells to populations of neurons to animal societies to markets. Goals of Flack’s research are to discover the computational principles that allow nature to overcome subjectivity due to noisy information processing, reduce uncertainty, and compute robust, ordered states.
