A.I. could help spot telltale signs of coronavirus in lung X-rays

There are many pain points when it comes to the coronavirus, officially known as COVID-19. One of them is how exactly to test people for it when the necessary testing kits are in short supply and, according to at least some theories, many more people may have already had it than current estimates suggest.

One possible solution could be to allow artificial intelligence to scrutinize chest X-rays of patients’ lungs to spot signs of potential coronavirus-caused lung damage.

That’s the basis for several exciting and promising attempts to develop a neural network that could be used to give a strong indication of whether or not a patient likely has COVID-19. Researchers at Chinese medical company Infervision recently teamed up with Wuhan Tongji Hospital in China to develop a COVID-19 diagnostic tool. It is reportedly now being used as a screening tool at the Campus Bio-Medico University Hospital in Rome, Italy.

Meanwhile, other researchers from the University of Waterloo in Ontario, Canada, and Canadian A.I. firm DarwinAI this week announced a new open-access neural net that’s open to the public. Called COVID-Net, it’s intended as a tool that could be used for similar screening — and is open for further testing by researchers around the world, who may soon be able to deploy it as a much-needed public health solution.

“We carried [out the A.I.’s] training on a dataset made up of 5,941 posteroanterior chest radiography images, across 2,839 patient cases, from two-open access data repositories,” Alexander Wong, one of the researchers on the project, told Digital Trends. “So far, the sensitivity to COVID-19 cases is quite good. However, the data on COVID-19 cases is still limited and we are continuing to improve the COVID-Net model as more data comes in over time.”

This is the problem that any A.I. researchers are likely to run into. Simply put, there’s still much to learn about COVID-19, which can make developing tools for recognizing it (and, in this case, distinguishing it from other maladies of the lung) difficult. That is why the idea of a publicly available — and publicly scrutable — system is so promising.

“[COVID-Net] is currently not used by patients,” Wong said. “But we are continuing to work hard on improving the results, and invite clinicians and clinical institutes and organizations to use it, give feedback, [and] contribute data so we can accelerate its readiness for clinical deployment. Right now, everything is available to the global community, so hopefully this accelerates progress and advances in this area.”

A.I. researchers are always talking about wanting to solve big problems. Right now, this is one of the biggest that there is.


Nixplay Smart Photo Frame review

The Nixplay Smart Photo Frame, available in a variety of sizes, is a Wi-Fi digital picture frame that displays your favorite images. Similar to traditional picture frames you can hang it on a wall or prop it up on a table. Unlike the one on your grandmother’s wall, it can cycle through more than 2,000 pictures.This is the sort of product you’d gift to parents and grandparents as you can send photos or playlists directly to them. Additionally, it might be a good product for new parents, newlyweds, or college students who might want to keep an eye on things back home. It works just as well to give one of these to someone as it would be to receive on.There are a different sizes and finishes available so it ought to be no problem finding the right fit for your home. And because of its flexibility, you can move it to different rooms or environments without hassle.The 10.1-inch version features a 1280 x 800 HD image that’s bright, easy to see from a variety of angles, and works in both landscape and portrait orientation. As one might expect from a device like this in 2020, there is support for Google Assistant and Amazon Alexa.The built-in motion sensor is able to identify whether there are people in the room which means it automatically turns itself off.Configuration and SetupSetting up the Nixplay Frame includes creating an account, pairing your frame to it, and adding photos. Using the mobile app you can manually add photos, but we found it easier to manage it from the website.Once logged in, you can pair your social media accounts with their respective library or albums. That includes Google Photos, Facebook, Instagram, Dropbox, Flickr, and Verizon Cloud.It’s also in this dashboard where you can set up timers to turn on and off the frame. Additionally, you can shuffle the playlist, opt to display a clock, adjust the transitions between photos, and more.If you’re purchasing one of these for a family member or friend, you’ll be able to set it all up and essentially make it a turn-key gift. All you’ll have to do is set it on the right Wi-Fi network.We appreciate that you can make as many adjustments that you can, especially to keep things updated. There’s no need to insert a microSD card or plug into the frame. Anything done in the cloud is automatically updated.As for the Google Assistant stuff, it’s more or less just being able to turn the frame on and off using your voice. It’s handy, but not necessary. Amazon Alexa appears to have a little deeper integration with options to pull up specific playlists. 1 of 4 The viewing angles on the frame are really good and we found it to provide sharp color and high contrast. Some of the transitions do feel a tad dated, however, they are quick. Fortunately, you can opt for longer delays between changing and decide which transition you want.Where to BuyYou can learn more about the Nixplay Smart Photo Frame at the company’s official website. There, you’ll find it available to purchase for about $180. A limited time discount sees the company taking $27 off, bringing the total to just $153.There are also other sizes to choose from, ranging from 9.7-inches up to 15.6-inches. From the looks of it, there are often chances to save on your frame. Be it centered around a holiday or just an instant discount, it pays to look.
