Artificial-intelligence systems have made remarkable progress in recent years, but they still struggle with the kind of ...

In the 1980s and ’90s, SFI played laboratory to a promising new method known as agent-based modeling. In ensuing decades, agent-based models (ABMs) proliferated across many fields, including economics ...

Complexity Postdoctoral Fellow Maike Morrison builds mathematical tools to quantify and compare biological variation. Her ...

In a recent op-ed in PNAS, SFI External Professor Michael Hochberg and co-author Paul Rainey explore whether deepening interdependence between humans and AI could lead to a new form of evolutionary ...

It might start as a joke, a belief, or a rumor. At first, it’s easy to dismiss. But then it gains a twist, builds momentum, and spreads like wildfire. What causes some ideas to die out while others ...

In a network, pairs of individual elements, or nodes, connect to each other; those connections can represent a sprawling system with myriad individual links. A hypergraph goes deeper: It gives ...

In many careers, a person must learn foundational skills before advancing more deeply into their profession. Computer programmers need a solid foundation in basic mathematics; nurses must gain ...

SFI External Professor and Science Steering Committee member Michelle Girvan (University of Maryland) has been elected President of the Network Science Society, an organization that supports an ...

Large language models like GPT-4, the one behind ChatGPT, train on vast stores of data to complete one task: Produce a convincing sequence of words in response to a user’s written request. The tools ...

Medieval friar William of Ockham posited a famous idea: always pick the simplest explanation. Often referred to as the parsimony principle, “Ockham’s razor” has shaped scientific decisions for ...

In fields ranging from immunology and ecology to economics and thermodynamics, multi-scale complex systems are ubiquitous. They are also notoriously difficult to model. Conventional approaches take ...

When it comes to job interviews, conventional wisdom often suggests that standing out is key to securing a position — seemingly at odds with the general human tendency to conform. A new study by SFI ...
