Neuroscience and artificial intelligence experts from Rice University and Baylor College of Medicine have taken inspiration from the human brain in creating a new "deep learning" method that enables computers to learn about the visual world largely on their own, much as human babies do. In tests, the group's "deep rendering mixture model" largely taught itself how to distinguish handwritten digits using a standard dataset of 10,000 digits written by federal employees and high school students. In results presented this month at the Neural Information Processing Systems (NIPS) conference in Barcelona, Spain, the researchers described how they trained their algorithm by giving it just 10 correct examples of each handwritten digit between zero and nine and then presenting it with several thousand more examples that it used to further teach itself. In tests, the algorithm was more accurate at correctly distinguishing handwritten digits than almost all previous algorithms that were trained with thousands of correct examples of each digit. "In deep-learning parlance, our system uses a method known as semisupervised learning," said lead researcher Ankit Patel, an assistant professor with joint appointments in neuroscience at Baylor and electrical and computer engineering at Rice. "The most successful efforts in this area have used a different technique called supervised learning, where the machine is trained with thousands of examples: This is a one. "Humans don't learn that way," Patel said. "When babies learn to see during their first year, they get very little input about what things are.

Enterprises today are finding it exceedingly meaningful and resourceful in the massive amounts of data they generate and save every day. The required algorithms, applications and frameworks to bring greater predictive accuracy and value to enterprises' data sets are available; therefore, businesses need to make sure they have data sets of sufficient size and quality. It is due to the excessive need to do a better job in capturing and utilizing data. The rise of deep learning and neural networks has spread in everyday lives. It took about six years for neural nets to show impressive results, first in speech recognition, then computer vision, images, image detection and diagnostics, and more recently, in natural language processing.

There is plenty being written about the bright future digital technologies are purportedly bringing to the business world. But when it comes to jobs and careers, the conversation gets gloomy. Expect plenty of jobs to be automated or supplanted by artificial intelligence, they tell us -- from truck drivers to journalists to doctors and even lawyers. The rise of digital has ramifications for every job, and the transition to a digital economy will carry its share of pain. At the same time, embracing the forces of change can also open up new opportunities.

Learning to speak a new language brings health benefits and in addition we could be predisposed to speak more than one language, new research suggests. In this spirit multilingualism has shown to have social, psychological and lifestyle advantages as well as direct health benefits like faster recovery from a stroke or delaying dementía. Something that could mean that to reach your brain's full potential and to "empower" it, multilingualism is a great practice. This is at the same time a practice that brings a lot of "headache" for artificial intelligence. As Will Knight, senior editor for AI and robotics at MIT Technology Review writes: "There's an obvious problem with applying deep learning to language. It's that words are arbitrary symbols, and as such they are fundamentally different from imagery."

For the uninitiated, the Webster dictionary defines artificial intelligence (AI), the word buzzing like a bee of late, as the capability of a machine to imitate intelligent human behaviour. The concept is exactly like what the science fiction movies have portrayed since decades, of a machine that can analyse, think, act accordingly and aid humans (though in a lot of movies they become villainous). In the last half-a-decade, leaps in AI have been made with its application in wide ranging areas. Education is, albeit slowly, coming under the ambit of sectors that will be greatly affected (disrupted, if you will) by AI in near future. AI has actually become a part and parcel of our everyday lives even though the term is not used frequently.

Kengo Kyogoku borrows about ¥122,000 ($1,035) per month in addition to a scholarship and a part-time job, because his mother can't afford to pay his college fees at the prestigious Waseda University in Tokyo. "The amount is huge," said Kyogoku, a sophomore of communications and computer engineering. "I get depressed when I think about it. I wonder if I will have to pay it back forever. But I have no choice."

Teaching machines to read isn't the same as teaching a toddler. They don't have the nuances of culture, idioms, tone and other social cues to understand what you're writing about. Waterloo's Maluuba is leading the way in teaching machines to think, reason and communicate just like we do thanks to a growing research and learning lab in Montreal that is working on those types of common sense problems that could lead to the next breakthroughs in artificial intelligence. The company, founded in 2010 by University of Waterloo students at the school's Velocity program, took another step towards that last week by releasing two sophisticated natural language understanding data sets. Instead of guarding their data sets like a secret, they decided to share them to advance innovation in artificial intelligence research and facilitate future breakthroughs.

Summary: A great story about an AI-powered massive on-line open learning platform focused on STEM education. The platform and its content is to be available across many languages to serve students anywhere in preparing for a better life in STEM careers. If you're from the US you're probably feeling some angst as our K-12 students seem to slip further and further back on STEM studies. Imagine how bad it is in the lesser developed countries where shortages of STEM teachers and basic tech resources make it almost impossible for young people to prepare for a better life through a tech career. Worse still, UNESCO says there are 100 million young people around the world who do not attend school at all.
