Using the Eye as a Window into Heart Disease

Scientists have developed an artificial intelligence (AI) system that can analyse eye scans taken during a routine visit to an optician or eye clinic and identify patients at a high risk of a heartattack.

Doctors have recognised that changes to the tiny blood vessels in the retina are indicators of broader vascular disease, including problems with the heart.

In the research, led by the University of Leeds, deep learning techniques were used to train the AI system to automatically read retinal scans and identify those people who, over the following year, were likely to have a heart attack.

Deep learning is a complex series of algorithms that enable computers to identify patterns in data and to make predictions.

Writing in the journal Nature Machine Intelligence, the researc...

Researchers can Turn a Single Photo into a Video

A GIF that showcases symmetric splatting -- starts out with two waterfalls. On the right, the waterfall starts losing pixels at the top because they are moving to the bottom. On the left, the waterfall starts losing pixels at the bottom because they are moving to the top. At the end of this GIF, the two waterfalls are combined into one so that there are no holes.
To animate the image, the team created “symmetric splatting,” which predicts both the future and the past for an image and then combines them into one animation.Hołyński et al./CVPR

Researchers have developed a deep learning method that can produce a seamlessly looping, realistic looking video from a single photo. Sometimes photos cannot truly capture a scene. How much more epic would that vacation photo of Niagara Falls be if the water were moving?

Researchers at the University of Washington have developed a deep learning method that can do just that: If given a single photo of a waterfall, the system creates a video showing that water cascading down. All that’s missing is the roar of the water and the feeling of the spray on your face.

The team’s method can animate any fl...

Artificial Intelligence makes great Microscopes better than ever

Machine learning helps some of the best microscopes to see better, work faster, and process more data. Collaboration between deep learning experts and microscopy experts leads to an significantly improved data-intensive light-field microscopy method by using AI and ground-truthing it with light-sheet microscopy. The result is the power of light-field microscopy available to biologists in near real time vs. days or weeks, AND the expansion of biologists’ ability to use this microscopy for many things more things requiring the most detailed observation.

To observe the swift neuronal signals in a fish brain, scientists have started to use a technique calle...

Researchers at UC Santa Cruz have developed a powerful new computer program called Morpheus that can analyze astronomical image data pixel by pixel to identify and classify all of the galaxies and stars in large data sets from astronomy surveys.

Morpheus is a deep-learning framework that incorporates a variety of artificial intelligence technologies developed for applications such as image and speech recognition...
