A group of health care organizations in the United States and Brazil have used federated learning to improve AI mammography classification models for recognizing tumors and breast tissue density assessment. An Nvidia spokesperson declined to share specific performance details, but said a combined effort led to better classification model performance than models made by any of the individual health…

Google today released a demo app that visualizes a real-time point cloud from uDepth, the stereo depth sensor built into the Pixel 4 and Pixel 4 XL. As the tech giant explains in a lengthy post, uDepth taps machine learning to identify users while protecting against spoof attacks; it supports a number of features, including post-processing photo retouching and depth-based scene segmentation as…

COVID-19 waits for no one, and the speed of its spread has forced the world to act quickly.  From world governments to individual households, all of sudden everyone has had to scrap plans, make new ones, and try to hang on to some kind of new normal as the pandemic causes more unexpected and rapid shifts. Looking at the tech world, it’s been quite a sight to watch everyone move so fast. As I…

In a paper scheduled to be presented at the upcoming International Conference on Learning Representations, Amazon researchers propose an AI approach that greatly improves performance on certain meta-learning tasks (i.e., tasks that involve both accomplishing related goals and learning how to learn to perform them). They say it can be adapted to new tasks with only a handful of labeled training…
