Sanjeev Arora, the Charles C. Fitzmorris Professor in Computer Science, is exploring the most baffling aspects of machine learning—especially “deep learning.” His end goal is to open the door to training techniques for machines that make the right decisions, mathematically guaranteed.

“Current machine learning approaches are not very…

Ants and humans live in large societies that allow for elaborate structures — nests, cities — filled with resources. Sometime in the distant past, individuals must have organized themselves into the first simple groups, precursors of these complex societies. But how?

A team of researchers from Princeton University and Rockefeller…

By analyzing data from thousands of patients, Princeton researchers have identified genetic mutations that frequently occur in people with uterine cancer, colorectal cancer or skin cancer — an important step toward using genome sequences to better understand cancer and guide new treatments.

Techniques and tools for seeing fleeting arrangements of atoms during chemical reactions are advancing rapidly, allowing unprecedented insights into physical and living systems, according to experts in microscopy from around the world who gathered for a three-day conference at Princeton in July.

The internet gives people worldwide access to applications and services, but in many cases, internet traffic passes through a few dominant countries, according to new research from Princeton University.

Following the 2013 revelations of U.S. government surveillance, officials from several…

In a development with implications for better understanding disease, researchers have created a computational system to predict the effect that mutations in noncoding DNA — sections that don’t produce proteins — have on tissues and cells in the human body.

Genes produce proteins that keep your body functioning and healthy. But genes…

Replacing a cluster installed in 2012, Princeton’s new flagship computer, TIGER, arrived quietly on campus in March and was put through months of routine testing and debugging before being officially unveiled in late May. Several tours and a reception were held at the 

Princeton researchers have developed a new computational method that increases the ability to track the spread of cancer cells from one part of the body to another.

This migration of cells can lead to metastatic disease, which causes about 90 percent of cancer deaths from solid tumors — masses of cells that grow in organs such as the…

With the help of a quarter-million video game players, Princeton researchers have created and shared detailed maps of more than 1,000 neurons — and they’re just getting started.

“Working with Eyewirers around the world, we've made a digital museum that shows off the intricate beauty of the retina's neural circuits,” said
