Algorithm better at diagnosing pneumonia than radiologists

Stanford researchers have developed an that offers diagnoses based off chest X-ray images. It can diagnose up to 14 types of medical conditions and is able to diagnose pneumonia better than expert radiologists working alone.

A paper about the algorithm, called CheXNet, was published Nov. 14 on the open-access, scientific preprint website arXiv.

“Interpreting X-ray images to diagnose pathologies like pneumonia is very challenging, and we know that there’s a lot of variability in the diagnoses radiologists arrive at,” said Pranav Rajpurkar, a graduate student in the Machine Learning Group at Stanford and co-lead author of the paper. “We became interested in developing machine learning algorithms that could learn from hundreds of thousands of chest X-ray diagnoses and make accurate diagnoses.”

Photoshop uses AI to make selecting people less of a hassle

Masking a human or other subject out of a scene is a pretty common trick nowadays, but it’s is still arguably one of the hardest and lowest-tech parts of Photoshop. Adobe’s about to make that a lot easier, thanks to an upcoming AI-powered feature called Select Subject. Using it is pretty much idiot-proof: From the main or “Select and Mask” workspaces, you just need to click anywhere on the image, and it’ll automatically select the subject or subjects in the image. From there, you’re free to change the background or tweak the subject separately.

The tech is powered by Adobe’s AI platform, Sensei. “Complicated details around the subject aren’t an issue, because this feature is using machine learning to recognize the objects,” Adobe Photoshop Product Manager Meredith Payne Stotzner says in the YouTube video (below). During the demo, she uses it select a single person on the street, a group of volleyball players, a couple on the beach and a red panda.

Insurance Companies Are Now Offering Discounts if Your Let Your Tesla Drive Itself

While accidents have happened, one of the most appealing things about autonomous vehicles is their capacity to make our roads a safer place. Now, insurance companies are starting to offer financial incentives to promote adoption.

Britain’s largest automobile insurance company, Direct Line, has announced a 5 percent discount for customers who activate Autopilot functionality in their Tesla. It follows in the footsteps of Root, a startup that offers a similar promotion across nine states in the US.

Google’s AI mastered chess in 4 hours

The robots are coming for your … chess game.

Google’s AI, AlphaZero, developed a “superhuman performance” in chess in just four hours.

Essentially, the AI absorbed humanity’s entire history of chess in one-sixth of a day — and then figured out how to beat anyone or anything.

After being programmed with the rules of the game (not the strategy) AlphaZero played 100 games against Stockfish, the world champion chess program. AlphaZero won 25 playing as white (which has first-mover advantage) and three games playing as black. The last 72 games were a draw with AlphaZero recording no losses and Stockfish recording no wins.

AlphaZero Annihilates World’s Best Chess Bot After Just Four Hours of Practicing

Awesome!


A few months after demonstrating its dominance over the game of Go, DeepMind’s AlphaZero AI has trounced the world’s top-ranked chess engine—and it did so without any prior knowledge of the game and after just four hours of self-training.

AlphaZero is now the most dominant chess playing entity on the planet. In a one-on-one tournament against Stockfish 8, the reigning computer chess champion, the DeepMind-built system didn’t lose a single game, winning or drawing all of the 100 matches played.

Look into the future using the first smart glasses with Alexa control

There are a lot of people in the world that need glasses on a daily basis. Despite their often expensive price tag, they do little more than correct poor eyesight. Let Glass updates glasses for the 21st century by integrating them with smart home connectivity.

While maintaining a slim form factor, Let Glass features audio entertainment, telephone communication, and voice interaction. Using Alexa and a built-in microphone, these frames allow users to control their smartphones without fumbling through their pockets. Simply tapping the legs of the smart glasses activate remote control functions, while voice commands handle everything else. In addition to Amazon Alexa, Apple Siri and Google Now are also supported.

Keeping with a traditional appearance, audio is produced using bone conduction technology. Instead of a speaker, the glasses vibrate the small bones in the ear to produce sound. This also keeps ears open to other noises, ensuring users remain aware of their surroundings. This allows users to listen to music, track activity, use voice navigation, call a friend, and more.

This AI algorithm probably means the end of high-end art forgeries

In the mid-1900s, art historian Maurits Michel van Dantzig developed a system to identify artists by their brush or pen strokes, which he called Pictology. Dantzig found shape, length, direction, and pressure all contributed to a kind of stroke signature, unique to each artist.

New research with contributions from The Hague suggests that Pictology might be the key to helping machines understand art, allowing systems to quickly verify whether brushstrokes were from an original painter or a forger.

After analyzing 80,000 brushstrokes from 297 digitized sketches and drawings, an AI system was able to spot forged drawings in the style of Pablo Picasso, Henri Matisse, and Egon Schiele with 100% accuracy. The “fakes” were commissioned recreations of specific drawings, which the algorithms had not been shown previously.
