WED@NICO WEBINAR: Cristian Candia-Castro Vallejos, Universidad del Desarrollo, Chile "Digital footprints for collective intelligence"
Northwestern Institute on Complex Systems (NICO)
12:00 PM

Speaker:
Cristian Candia-Castro Vallejos, Assitant Professor and Director of Master in Data Science at the Data Science Institute, Universidad del Desarrollo, Chile
Title:
Digital footprints for collective intelligence
Abstract:
In general words, Collective Intelligence (CI) is defined as the shared or group intelligence that emerges from the interaction between people and the ways of processing information. For CI to exist, groups of people must learn collectively and store what is learned in their collective memories; thus, the need to solve new problems allows collective intelligence to manifest. CI arises mainly in collaboration, collective efforts, competition between people, and decision-making by consensus (Pierre Levy, 1999). In this presentation, using an approach placed at the intersection between theories of human behavior and data science, we will take a tour of our ongoing research in three different aspects of collective intelligence: Tools that facilitate collective intelligence; Types of collective intelligence, such as cooperation and coordination; and one of the means that allow collective intelligence, collective memory.

WED@NICO SEMINAR: Rosemary Braun, Northwestern University "The Scale of Life"
Northwestern Institute on Complex Systems (NICO)
12:00 PM

Lower Level, Chambers Hall

Speaker:
Rosemary Braun, Associate Professor, Department of Molecular Biosciences, Northwestern University
Title:
The Scale of Life
Abstract:
Living systems exhibit surprising and beautiful self-organization at all scales. At the atomic level, proteins self-assemble into macromolecular complexes. The function of these machines is orchestrated within the cell by regulatory networks, whose activity is in turn dictated by, and coordinated with, the cells environment. This coordination takes place across large spans of space and time: the size and lifetime of organisms as large as the blue whale. Populations and ecosystems of many organisms in turn exhibit remarkable emergent dynamics. Today, advances in single-cell assays enable us to probe the molecular state of every cell in a sample in high-dimensional detail. But is this the correct scale at which to probe living systems? What can we learn from this data, and how can we abstract from the microscopic details to macroscopic phenotypes? In this talk, I will discuss some of our recent work bridging the cell and tissue/organism scales, and discuss some challenges and opportunities for the future.
