Multi-year datasets suggest projecting outcomes of people’s lives with AI isn't so simple
March 31, 2020
Written by B. Rose Huber, Woodrow Wilson School of Public and International Affairs

The machine learning techniques scientists use to predict outcomes from large datasets may fall short when it comes to projecting the outcomes of people’s lives, according to a mass collaborative study led by researchers at Princeton.

New mathematical model can more effectively track epidemics
March 25, 2020
Written by John Sullivan, Office of Engineering Communications

As COVID-19 spreads worldwide, leaders are relying on mathematical models to make public health and economic decisions.

A new model developed by Princeton and Carnegie Mellon researchers improves tracking of epidemics by accounting for mutations in diseases. Now, the researchers are working to apply their model to allow leaders to…

Food systems are fodder for curbing cities’ environmental impacts
March 24, 2020
Written by Molly Sharlach, Office of Engineering Communications

Focusing on urbanization as a key driver of environmental change in the 21st century, researchers at Princeton have created a framework to understand and compare cities’ food systems and their effects on climate change, water use and land use. The research will allow planners to estimate the impact of a city’s food system…

Internet security borne out of collaboration between Princeton and Let's Encrypt
Feb. 21, 2020
Written by Adam Hadhazy for the Office of Engineering Communications

An innovative protection against website counterfeiting developed by Princeton researchers went live on the internet Feb. 19, boosting security for hundreds of millions of websites. The rollout was the culmination of over two years of close collaboration between research groups at Princeton and Let's Encrypt, the world's largest certificate…

Researchers uncover potential cancer-causing mutations in genes’ control switches
Feb. 5, 2020
Written by Molly Sharlach, Office of Engineering Communications

Using sophisticated algorithms to explore regions of the genome whose roles in cancer have been largely uncharted, an international team of researchers has opened the door to a new understanding of the disease’s genetic origins.

The discovery involves areas of DNA that do not directly code for…

‘Grow-and-prune’ AI mimics brain development, slashes energy use
Dec. 20, 2019
Written by Scott Lyon, Office of Engineering Communications

It may come as a shock to parents facing the daily chaos of toddler life, but the brain's complexity peaks around age 3.

The number of connections between neurons virtually explodes in our first few years. After that the brain starts pruning away unused portions of this vast electrical network, slimming to roughly half the number by…

Princeton to take part in new U.S.-Swedish initiative on artificial intelligence and sustainability
Oct. 15, 2019
Written by Victor Galaz Rodriguez, Stockholm University; and B. Rose Kelly, Woodrow Wilson School of Public and International Affairs

The intensive fires in the Amazon, the rapid melting of glaciers and ice sheets, and continued loss of biodiversity all illustrate that our planet is changing at a dangerous pace. At the same time, we are entering a period of unprecedented technological change.

Artificial intelligence (AI) in combination with sensor technology and…

Protecting smart machines from smart attacks
Oct. 14, 2019
Written by Adam Hadhazy for the Office of Engineering Communications

Machines' ability to learn by processing data gleaned from sensors underlies automated vehicles, medical devices and a host of other emerging technologies. But that learning ability leaves systems vulnerable to hackers in unexpected ways, researchers at Princeton University have found.

In a series…

Princeton’s new supercomputer, Traverse, to accelerate scientific discovery in fusion research
Oct. 7, 2019
Written by Melissa Moss for Princeton University

A ribbon-cutting ceremony in Princeton’s High-Performance Computing Research Center on Sept. 30 kicked off the University’s official launch of its newest supercomputer, called Traverse, which joins four other distinct computing clusters available…

Princeton program empowers youth to shape the future of artificial intelligence
Aug. 26, 2019
Written by Molly Sharlach, Office of Engineering Communications

Teenagers enjoy the products of artificial intelligence (AI) every day, whether taking a twisted selfie with a photo filter or listening to music with an automated streaming service. But not many high school students have used AI themselves to analyze human genetic variation or track deforestation in the Amazon.
