MOSCOW: Scientists have developed an artificial intelligence (AI) system that can identify people on video, detecting their age and gender more quickly and accurately.
The development has already become the basis for offline detection systems in Android mobile apps, according to researchers from Higher School of Economics in Russia.
Modern neural networks detect gender on videos with a 90 per cent accuracy. The situation with age prediction is much more complicated.
Traditional neural networks consider discrete values of age. In each of the video frames, the network estimates the probability of the person in the image being of a certain age.

A team of US researchers has developed an ‘artificial synapse’ that does not process information like a digital computer but rather mimics the way the human brain completes tasks. The discovery can lead to energy-efficient AI devices. The graphene-based neural networks can be employed in flexible and wearable electronics to enable computation at the ‘edge of the internet’ — places where computing devices such as sensors contact the physical world.
“By empowering even a rudimentary level of intelligence in wearable electronics and sensors, we can track our health with smart sensors, provide timely diagnostics, regulate and optimise the manufacturing process,” say the researchers.

Scientists have developed a waterproof wearable patch, which when applied directly to the skin, absorbs sweat and within seconds assesses how much cortisol — stress hormone — a person is producing. “This offers a novel approach for the early detection of various diseases and evaluation of sports performance,” says lead author, Onur Parlak from Stanford University, US.

Using wearable sensor technology, researchers have developed an automatic alert system that may help people to quit smoking by sending video messages. A smartphone app automatically texts 20 to 120-second video messages to smokers when the sensors detect specific arm and body motions associated with smoking. According to the researchers, the mobile alert system that they are testing may be the first that combines an existing online platform with mindfulness training and a personalised plan to quit smoking.

Falls are a common cause of injury in older adults and can create health problems. A recent study under NIH’s Women’s Health Initiative to predict an individual’s risk of falling made 67 participants, all over the age of 60, wear a small device with motion sensors that measured their walking patterns for one week. They found that data extracted from the devices could accurately predict the participants’ risk of falling, as measured by physical examinations of unsteadiness in standing and walking.

For example, if in 30 per cent of the frames the top prediction of the network is a person's age as 21 years, and in 10 per cent as 60 years, its conclusion will be as follows: with a probability of 30 per cent this person is 21, and with a probability of 10 per cent, he or she is 60.

Due to various conditions of observations or even slight head rotation, prediction of the same person's age in different video frames varies in the range of 5 years, plus or minus.
Researchers found a way to optimise neural networks' operations. They implemented a novel method to aggregate confidence levels produced by the neural network for each frame.

Hate carbon dioxide for heating up the planet? Switzerland has a giant machine that sucks carbon dioxide from air and performs better than plants. In essence, it’s a gigantic artificial tree. Zurichbased Climeworks AG is the world’s first ever commercial plant that can capture CO2 from the air on an industrial level. The amount (900 tonnes) of carbon dioxide the plant draws annually is approximately the same as the amount emitted by 200 cars in the same time.

Scientists at the Icahn School of Medicine at Mount Sinai in US have developed an artificial intelligence platform that can identify disease in brain CT scans in 1.2 seconds, and diagnose a range of acute neurological illnesses, such as stroke, and haemorrhage. The study shows that the system was faster than human diagnosis. This is the first study to utilise AI for detecting acute neurologic events and demonstrate a direct clinical application.

Remember the pursuit craft driven by Valerian (Dane DeHaan) in the 2017 movie Valerian and the City of a Thousand Planets? US design and technology company Lexus has a concept of the futuristic single-seat craft called Skyjet that will take the future humans on intergalactic trips. Powered by a compact fuel-cell capsule, the Skyjet will fly on clean, renewable energy for space travel, sometime around 2740.

The most dense, solidstate memory in history is here. It could soon exceed the capabilities of current hard drives by 1,000 times. Scientists at the University of Alberta in Edmonton, Canada say they can use hydrogen atoms to boost storage capacity. They were able to reach a storage density of 128TB per square inch. That’s much ahead of current 10TB hard disks which have approximately 512GB per square inch.

We know antimatter is highly volatile — when it comes into contact with matter, the two annihilate each other. However, physicists at CERN in Switzerland have learned to control it so well that they are now preparing to transport antimatter by truck and then use it to study the strange behaviour of rare radioactive nuclei.

The software systems of facial recognition analysis usually include several separate neural networks. One of them identifies the person, another one determines the gender, etc.
An effective neural network with several outputs has been developed. It solves several tasks at a time: predicts age and gender, and produces a set of 1,000 numbers that uniquely attribute each person and allows them to be distinguished from other people.

According to researchers, this solution will work even on low-performance smartphones.
