Google makes image recognition advance 

Scientists at Google have created artificial intelligence software that can describe the contents of photographs far more accurately than ever before.
The software's description of pictures was similar to that written by a human.
As well as making it easier to search for images, the software could be used to help blind people understand pictures better, Google said.
Stanford University has also announced a breakthrough in the same field.
The machine-learning software developed by Google used two neural networks - one which deals with image recognition, the other with natural language processing.
Neural networking is a computational model that mimics some of the same architecture used in the brain. Such systems have a series of interconnected neurons which can take information from a variety of sources and are also capable of learning.
The neural network developed by Google was the work of four scientists - Oriol Vinyals, Alexander Toshev, Samy Bengio and Dumitru Erhan.
"A picture may be worth a thousands words," they wrote on the Google Research blog.
"But sometimes it's the words that are the most useful - so it's important we figure out ways to translate from images to words automatically and accurately."
Two years ago Google researchers created image-recognition software and showed it 10 million images taken from YouTube videos. After three days the programme had taught itself how to pick out pictures of cats.

BMW traps alleged thief by remotely locking him in car

BMW traps alleged thief by remotely locking him in car Stealer's Wheel? Seattle police department quotes "Watchmen" movie in a recap of the recent arrest. Tech Culture by Gael Fashingbauer Cooper December 4, 2016 5:00 PM PST It's maybe the most satisfying arrest we can imagine. Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal. Jonah Spangenthal-Lee, deputy director of communications for the Seattle Police Department, posted a witty summary of the event on the SPD's blog on Wednesday. Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (Nov. 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," Spangenthal-Lee wrote. The suspect found a ke...

Report: World’s 1st remote brain surgery via 5G network performed in China

World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 ·           A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media  reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling.  “You barely feel that th...

New ATM's: withdraw money with veins in your finger

New cash machines: withdraw money with veins in your finger Cash machine technology that reads the pattern of finger veins is already available in Japan and Poland   By Telegraph Reporters 6:59PM BST 15 May 2014 Cash machines could soon be installed with devices that identify customers by reading the veins in their fingers. The technology is already being rolled out in Poland, where 1,730 cash machines will this year be installed with readers, negating the need for a debit card and Pin. Developed by Hitachi, the Japanese electronics firm, the machines read the patterns of the veins just below the surface of the skin on your finger using infra-red sensors. The light is partially absorbed by haemoglobin in the veins to capture a unique finger vein pattern profile, which is matched to a profile. The technology is used by Japanese banks and also in Turkey, offering “groundbreaking levels of accuracy and speed of authentication”, Hitachi said, which in t...
