Artificial intelligence learns to recognize nerve cells

Is it possible to understand the brain? Science is still far from answering this question. However, since researchers have started training artificial intelligence on neurobiological analyses, it seems at least possible to reconstruct the cellular structure of a brain. New artificial neural networks developed by the Max Planck Institute of Neurobiology and Google AI can now even recognize and classify nerve cells independently based on their appearance.

The human brain consists of about 86 billion and about as many . In addition, there are about 100 trillion connections between the nerve cells alone. While mapping all the connections of a human brain remains out of reach, scientists have started to address the problem on a smaller scale. Through the development of serial block-face scanning , all cells and connections of a particular brain area can now be automatically surveyed and displayed in a three-dimensional image.

“It can take several months to survey a 0.3 mm piece of brain under an electron microscope,” says Philipp Schubert, doctoral student in Winfried Denk’s Department at the Max Planck Institute of Neurobiology. “Depending on the size of the brain, this seems like a lot of time for a tiny piece. But even this contains thousands of cells.” Such a data set would also require almost 100 terabytes of storage space. However, it is not the collection and storage but rather the that is the difficult part.

An AI “Vaccine” Can Block Adversarial Attacks

For as smart as artificial intelligence systems seem to get, they’re still easily confused by hackers who launch so-called adversarial attacks — cyberattacks that trick algorithms into misinterpreting their training data, sometimes to disastrous ends.

In order to bolster AI’s defenses from these dangerous hacks, scientists at the Australian research agency CSIRO say in a press release they’ve created a sort of AI “vaccine” that trains algorithms on weak adversaries so they’re better prepared for the real thing — not entirely unlike how vaccines expose our immune systems to inert viruses so they can fight off infections in the future.

Technology is a Magnifying Mirror, Not a Crystal Ball

“Mirror, mirror on the wall, who’s the smartest species of them all?”

“You, oh Homo Sapiens, are smart, it is true. But AI will be smarter even than you.”

The most popular myth about technology is perhaps the myth that technology is a crystal ball. A crystal ball because it allegedly allows us to see the future. And to evaluate if that is indeed true, or not, we have to understand the etymology of the word technology – what it means and stands for, or at least what it used to mean and stand for.

McDonald’s Tests Robot Fryers and Voice-Activated Drive-Throughs

McDonald’s Corp. is designing voice-activated drive-throughs and robotic deep-fryers as the burger giant works to streamline its menu and operations to speed up service.

The company is testing voice-recognition software at a drive-through in suburban Chicago. Inside the restaurant, a robot also tosses chicken, fish and fries into vats of oil. Both technologies are meant to shorten customer wait times that executives acknowledge have grown in recent years. McDonald’s also has stopped serving some burgers and given franchisees…

AI System Can Identify Cardiac Arrest

Researchers at the University of Washington have used machine learning to teach an AI system to identify when someone is having a cardiac arrest. The system learned to identify agonal breathing, which occurs when someone gasps for breath during cardiac arrest, with a high degree of accuracy. The technology can be embedded into a variety of listening devices, such as smart speakers or smartphones, to alert authorities and loved ones to someone having a heart attack while they sleep.

Approximately half a million Americans die from cardiac arrest annually. Cardiac arrests often happen while someone is at home in bed. This is particularly dangerous, as there is likely to be no-one around, or no-one awake, to help.

Now, researchers have developed an AI system that can work through smart speakers or a smartphone to monitor for signs of a cardiac arrest while someone sleeps. The system listens for something called agonal breathing, which occurs in about 50% of people who experience a cardiac arrest, and patients who demonstrate this characteristic gasping often have a better chance of surviving.

Machine Learning: Living in the Age of AI | A WIRED Film

“Machine Learning: Living in the Age of AI,” examines the extraordinary ways in which people are interacting with AI today. Hobbyists and teenagers are now developing tech powered by machine learning and WIRED shows the impacts of AI on schoolchildren and farmers and senior citizens, as well as looking at the implications that rapidly accelerating technology can have. The film was directed by filmmaker Chris Cannucciari, produced by WIRED, and supported by McCann Worldgroup.
