Artificial intelligence (AI) offers important benefits for people in areas such as transportation, commerce, and beyond. While AI is constantly improving at understanding the dynamics of the world we live in, there is much more work to do. We’re firm believers that it will progress faster with early involvement from experts with diverse perspectives. If …

AI is doing tremendous things for our world, like detecting diseases, changing transportation, and helping people connect, but it still has a lot to learn. The more AI learns, the better it will understand the world around us. But equally important is who teaches it: If AI learns from only a small group of people, …

What the research is: A method leveraging reinforcement learning to improve AI-accelerated magnetic resonance imaging (MRI) scans. Experiments using the fastMRI data set created by NYU Langone show that our models significantly reduce reconstruction errors by dynamically adjusting the sequence of k-space measurements, a process known as active MRI acquisition. These k-space measurements are the building blocks …

Magnetic resonance imaging (MRI) scanners, the machines that doctors use to image the body’s soft tissue and organs, have been crucial tools for medical diagnoses for almost half a century. But one of their major shortcomings is the time it takes to carry out a scan. Clinicians can spend up to an hour gathering sufficient data for a …
