Improving Predictions with Ensemble Model

@machinelearnbot

"Alone we can do so little and together we can do much" - a phrase from Helen Keller during 50's is a reflection of achievements and successful stories in real life scenarios from decades. Same thing applies with most of the cases from innovation with big impacts and with advanced technologies world. The machine Learning domain is also in the same race to make predictions and classification in a more accurate way using so called ensemble method and it is proved that ensemble modeling offers one of the most convincing way to build highly accurate predictive models. Ensemble methods are learning models that achieve performance by combining the opinions of multiple learners. Typically, an ensemble model is a supervised learning technique for combining multiple weak learners or models to produce a strong learner with the concept of Bagging and Boosting for data sampling.


'Human, Please Look at This': Nasdaq Using AI to Spot Abuses

Survival: "Our entire existence is based on having the best detection mechanism possible," says Valerie Bannert-Thurner at Nasdaq. Certain things make Valerie Bannert-Thurner raise an eyebrow when looking for signs of bad behavior on the Nasdaq exchange. "I like the example of excessive cheering because the guys just can't help themselves but cheer," said Bannert-Thurner, who is senior vice president and head of risk and surveillance at Nasdaq. Another worrisome indicator is seemingly too-good-to-be-true trading profits. "If people are excessively profitable given how they trade and in comparison to everybody else trading the same instruments with similar styles, then we ask, is this luck or something else?" Bannert-Thurner said.


How Industry 4.0 Can Energize the Cyber-Physical Factory

#artificialintelligence

Our society went from an agrarian economy to mass-producing affordable goods using steam power, electricity and, eventually, computers and automation. We've gone from the horse and buggy to the Model T, and now we're on to self-driving cars! The smart factories of the Industry 4.0 era will be powered by the internet of things, cloud computing and cyber-physical systems (CPS) technologies. Cyber-physical systems are powered by enabling cloud technologies which allow intelligent objects and cloud-based programmatic modules to communicate and interact with each other. These new cyber-physical manufacturing facilities use robotics, sensors, big data, automation, artificial intelligence, virtual reality, augmented reality, additive manufacturing, cybersecurity systems and other cutting-edge technologies to deliver unprecedented flexibility, precision and efficiency to the manufacturing process.


The UN has decided to tackle the issue of killer robots in 2017

#artificialintelligence

The United Nations decided to formally address the issue of killer robots. At the International Convention on Conventional Weapons in Geneva, the 123 participating nations voted to form a group in 2017 of governmental experts to look at lethal autonomous robots that can select targets without human control, which could lead to a ban, reported Human Rights Watch. Many of Silicon Valley's elite, including Steve Wozniak and Elon Musk, have expressed concern over the development of killer robots. Musk and Wozniak both signed on to a letter last year urging the UN to take up the issue, calling for an international ban on the creation of lethal autonomous weapons. Stephen Hawking and leading AI researchers -- including University of California Berkeley computer scientist Stuart Russell, Google Director of Research Peter Norvig and Microsoft Managing Director Eric Horvitz -- were among the over 1,000 scientists who signed the letter calling for a killer robot ban.


Artificial Intelligence Human Intelligence Our Future

#artificialintelligence

When I was a scrawny little chap, shortest in my high school class, I always wanted a super power. Wanted doesn't capture the feeling. I would have given a limb for a super power. I read a lot of books back then (and now) and landed on a super power that had something to do with the brain. I eventually landed on Prof. Xavier of the X-Men.


The Best Answers to Your Most Crucial Deep Learning Questions

@machinelearnbot

Talk to someone with programming skills and discuss any subject about deep learning with them so that you could quickly jump in as a newbie. Though some people figure out various libraries embedding math is used universally, you needn't understand the theory to implement deep learning tasks, I still recommend you learn some math knowledge like partial derivative. Some resources could give you a good starting point like Stanford's online course CS231n, Deep Learning at Oxford 2015and Andrew Ng's Coursera class. Also, some interesting online books like Neural Networks and Deep Learning could also give you an assistance to deep learning. Facilities and toolkits should also be available.


Want to know how to choose Machine Learning algorithm?

#artificialintelligence

Machine Learning is the foundation for today's insights on customer, products, costs and revenues which learns from the data provided to its algorithms. Some of the most common examples of machine learning are Netflix's algorithms to give movie suggestions based on movies you have watched in the past or Amazon's algorithms that recommend products based on other customers bought before. Decision Trees: Decision tree output is very easy to understand even for people from non-analytical background. It does not require any statistical knowledge to read and interpret them. Fastest way to identify most significant variables and relation between two or more variables.


Digital Immortality: How technology will bring loved ones back to life

#artificialintelligence

The theory that humans will eventually be able to upload our brains to computers has fascinated futurists and neuroscientists for years. By transferring our minds into machines we could live forever, unmoored from the feebleness of our physical bodies. The concepts of death and bereavement as we know them now would cease to exist. Currently the idea lives within whitepapers and sci-fi movies, and the only thing (most) researchers agree on is that it won't be possible for a really long time. But while we're far from achieving that pinnacle of immorality, technology in the here-and-now has already started giving us a sliver of eternal life while shaping how we grieve our loved ones if and when they die.


7,500 Faceless Coders Paid in Bitcoin Built a Hedge Fund's Brain

#artificialintelligence

Richard Craib is a 29-year-old South African who runs a hedge fund in San Francisco. He leaves that to an artificially intelligent system built by several thousand data scientists whose names he doesn't know. Under the banner of a startup called Numerai, Craib and his team have built technology that masks the fund's trading data before sharing it with a vast community of anonymous data scientists. Using a method similar to homomorphic encryption, this tech works to ensure that the scientists can't see the details of the company's proprietary trades, but also organizes the data so that these scientists can build machine learning models that analyze it and, in theory, learn better ways of trading financial securities. "We give away all our data," says Craib, who studied mathematics at Cornell University in New York before going to work for an asset management firm in South Africa.


Why artificial intelligence won't displace human artists

#artificialintelligence

This year's news about what artificial intelligence can do in the arts has been both exciting and scary. Neural networks have learned to paint like masters and compose sophisticated music. Those of us in creative endeavors might be as endangered by technological advances as blue-collar workers are often said to be--though we are protected by certain limitations that technology is never likely to overcome. Last summer, a team of Russian developers released Prisma, a mobile app based on the work of some German artificial intelligence researchers. The neural network behind it could redraw an image using techniques it had learned from studying the oeuvre of a number of painters, including Vincent Van Gogh and Edvard Munch. The end product was impressive: Prisma could reproduce brushstrokes and palettes, using only a photo for guidance, almost the way a human painter could have.
