Emerging Machine Intelligence Clusters
Machine Intelligence (AI, ML and Deep Learning) requires a certain calibre of computer science talent. Today, this kind of talent is at the "top of the stack" of computer science. These cutting-edge capabilities used to be found at universities, and work on publicly-funded blue sky research; today, companies have the talent, and use it for private, applied purposes. The Economist touched on this in "Million Dollar Babies": That race for talent, is catalysing acquisitions by corporates interested in adding AI to their products and services. As an example, Ex-Googler Sebastian Thurn estimated that the going rate for self-driving engineering talent is $10 million per person.
Scientists develop AI which defeats professional poker players
A team of scientists has developed an artificial intelligence system called DeepStack that recently defeated professional poker players. The team of computing scientists from University of Alberta's Computer Poker Research Group, including researchers from Charles University in Prague and Czech Technical University, said DeepStack bridges the gap between approaches used for games of perfect information with those used for imperfect information games. "Poker has been a longstanding challenge in artificial intelligence," said Michael Bowling from the University of Alberta, Canada, in the paper published in the journal Science. It is the quintessential game of imperfect information in the sense that the players don't have the same information or share the same perspective while they are playing," Bowling added. Imperfect information games are a general mathematical model that describes how decision-makers interact. Artificial intelligence research has a storied history of using parlour games to study these models, but attention has been focused primarily on perfect information games. "We need new AI techniques that can handle cases where decision-makers have different perspectives," Bowling noted. DeepStack extends the ability to think about each situation during play -- which has been famously successful in games like checkers, chess, and Go -- to imperfect information games using a technique called continual re-solving. This allows DeepStack to determine the correct strategy for a particular poker situation without thinking about the entire game by using its "intuition" to evaluate how the game might play out in the near future.We train our system to learn the value of situations," Bowling said.
With funds, mentorship, and interns, a Silicon Valley incubator plays friend to Indian startups
A trio of university students is giving Indian startups unprecedented access to Silicon Valley. In April 2016, 20-year-old Abhinav Kukreja and two of his fellow freshman students at the University of California, Berkeley, Anish Prabhu, and Aryaman Dalmia, created an incubator called Moonshot that connects Indian startups with experts, funds, and talent from Silicon Valley. Its four-month program gives companies access to over 20 mentors in India and California, exposes them to various venture capitalists and angel investors, and provides interns. The first batch of startups Moonshot incubated last year included student benefits platform Frapp, marketplace ListUP, small-business cash-flow management startup Numberz, home appliance automation company Hombot, online B2B billing solutions portal Pumpcharge, and real estate and rental management service Azuro. For their second round in January 2017, Moonshot zeroed in on startups "advancing science and technology, artificial intelligence (AI), machine learning, and companies that have a positive social impact," Kukreja, a computer science and statistics major, said.
How to Upgrade Judges with Machine Learning
When should a criminal defendant be required to await trial in jail rather than at home? Software could significantly improve judges' ability to make that call--reducing crime or the number of people stuck waiting in jail. In a new study from the National Bureau of Economic Research, economists and computer scientists trained an algorithm to predict whether defendants were a flight risk from their rap sheet and court records using data from hundreds of thousands of cases in New York City. When tested on over a hundred thousand more cases that it hadn't seen before, the algorithm proved better at predicting what defendants will do after release than judges. Jon Kleinberg, a computer science professor at Cornell involved in the research, says one goal of the project was to show policymakers the potential benefits to society of using machine learning in the criminal justice system.
Google Deep Learning system diagnoses cancer better than a pathologist with unlimited time
It's hard to think of a job more important that determining whether or not a patient has cancer. Yet the magnitude of the task facing pathologists is so vast that agreement between different clinicians studying the same slides can be as low as 48%. There can be many slides per patient, each of which is 10 gigapixels when digitized at 40X magnification. Imagine having to go through a thousand 10 megapixel (MP) photos, and having to be responsible for every pixel. Needless to say, this is a lot of data to cover, and often time is limited.
Artificial Intelligence Startups Are Winning the Cybersecurity Race
A new era of AI began around 2010. Computer power capacity significantly increased and neural networks could be integrated into a GPU chip that enabled calculations to speed up experiments. Also, the rise of smartphones and cloud storage services allowed for the consolidation of enormous amount of big data. Those factors significantly impacted the growth of artificial intelligence. Those significant changes in the tech industry influenced the cybersecurity industry and led to a dramatic shift in the field.
Tuning hyperparams fast with Hyperband - FastML
Hyperband is a relatively new method for tuning iterative algorithms. It performs random sampling and attempts to gain the edge by using time spent optimizing in the best way. We explain a few things that were not clear to us right away, and try the algorithm in practice. Candidates for tuning with Hyperband include all the SGD derivatives - meaning the whole deep learning - and tree ensembles: gradient boosting, and perhaps to a lesser extent, random forest and extremely randomized trees. To quantify this idea, we compare to random run at twice the speed which beats the two Bayesian Optimization methods, i.e., running random search for twice as long yields superior results.
