When scientists test algorithms that sort or classify data, they often turn to a trusted tool called Normalized Mutual Information (or NMI) to measure how well an algorithm’s output matches reality.

Artificial-intelligence systems have made remarkable progress in recent years, but they still struggle with the kind of flexible, relational reasoning that comes naturally to humans. Program ...

Global markets are complex systems, shaped by feedback loops, sudden shocks, and adaptive behavior that rarely follow textbook rules and that can’t be captured by neat equations. At its core, ...

External Faculty are central to SFI’s identity as a world-class research institute. They enrich our networks of interactions, help us push the boundaries of complex-systems science, and connect us to ...
