Intel’s neuromorphic chip learns to ‘smell’ 10 hazardous chemicals

[ad_1] Using Intel’s Loihi, a neuromorphic chip, the team designed an algorithm based on the brain’s olfactory circuit. When you take a whiff of something, molecules stimulate olfactory cells in your nose. Those cells send signals to the brain’s olfactory system, which then fires off electrical pulses. The researchers were able to mimic that circuitry […]

Microsoft disrupts a botnet that infected 9 million computers

[ad_1] To disrupt Necurs, Microsoft analyzed a technique the botnet used to generate new domains through an algorithm. It then predicted over six million domains that would be created in the next 25 months and reported these to registries around the world, so that they can be blocked, preventing future attacks. Today’s action, Microsoft says, […]

YouTube’s tweaks to recommend fewer conspiracy videos seem to be working

[ad_1] The team trained its computers by having them analyze hundreds of conspiracy and non-conspiracy videos, helping them “learn” how to differentiate between the two. Once they were trained, the computers analyzed eight million recommended videos over the course of one year. Unfortunately, they were unable to classify the videos by actually watching them — […]

An algorithm could make CPUs a cheap way to train AI

[ad_1] Typically, companies use GPUs as acceleration hardware in implementing deep learning in technology. But this is pricey — top of the line GPU platforms cost around $100,000. Rice researchers have now created a cost-saving alternative, an algorithm called sub-linear deep learning engine (SLIDE) that is able to do the same job of implementing deep […]

FDA clears algorithms that detect heart murmurs and AFib

[ad_1] According to the company, the AI can identify heart murmurs with 87 percent sensitivity and 87 percent specificity. In comparison, primary care physicians unaided by AI had a 43 percent sensitivity and 69 percent specificity, according to a study in European Heart Journal. When used with the Eko DUO stethoscope, the AI reportedly detected […]

Facebook’s new robot AI can get around efficiently without using a map

[ad_1] The trick was to implement a new training method that scaled well and stayed in sync no matter what the workload. Previous projects tend to struggle without massive computational power. Facebook taught a virtual agent to handle point-to-point navigation for the equivalent of 80 years of human experience — that’s about 2.5 billion steps. […]

Scientists created living robots out of stem cells

[ad_1] “These are novel living machines,” says Joshua Bongard, a computer scientist and robotics expert at UVM who co-led the new research. “They’re neither a traditional robot nor a known species of animal. It’s a new class of artifact: a living, programmable organism.” To determine the best design for this new life form, researchers from […]

China internet rules call for algorithms that recommend ‘positive’ content

[ad_1] The new rules are due to take effect on March 1st, and also call for tighter management of accounts, sign-ups, moderation and “rumors.” Governments have lately stepped up attempts to regulate algorithms, although China’s approach is very different than that from other countries. A recent US Senate bill aimed to eliminate bias in algorithms, […]

The FDA is fast-tracking an algorithm that screens for heart failure

[ad_1] The algorithm was introduced in a study published in Nature Medicine in January 2019. It was trained on 44,959 patients and tested on 52,870 patients. In those initial tests, it showed 87.5 percent accuracy. The algorithm is designed to work with Eko’s DUO digital stethoscope. The handheld device can be placed on the left […]

MIT researchers use shadows to create a video of what happens off camera

[ad_1] In their experiment, the team filmed a pile of clutter. Off screen, someone created shadows by moving blocks and other objects. Their algorithm predicted the light transport, or the way light is expected to move in a scene, and compared that to the shadows. It then used that info to reconstruct the off-screen video. […]
