Drone use across the U.S. is soaring, and the skies may soon get even more crowded, as the Federal Aviation Administration expects sales of these unmanned aerial vehicles to jump to seven million in 2020 from about 2.5 million this year. Interest in drones for both commercial and casual purposes is raising not only safety and privacy concerns, but also thorny legal questions about where and when drones should be allowed to fly--and who gets to decide. On one side are those who say property owners' rights generally extend up about 500 feet, which gives them the right to prevent drones from flying or hovering over their land. They say drones pose a much bigger threat to security and privacy than jets and airplanes, which travel at higher altitudes, in airspace regulated by the FAA. They say drones represent the next frontier in aviation, and as such, decisions about where and when they can fly should be made collectively, not by landowners through tort law.

SAN FRANCISCO – At the top of the corporate world, Apple and Google are in a back-and-forth battle to be No. 1. It is not clear which of the two Silicon Valley giants will emerge on top in a contest that highlights the contrast of very different business models. Apple then regained, lost and recovered the leader position in May in a battle that appears set to continue for some time. As of the end of Friday, Apple was worth some 522 billion, to 496 billion for Alphabet. The two companies have both been hugely profitable in recent years, for different reasons. Apple has delivered a line of must-have iPhones and other devices that have set trends around the world but now "appears to be a little bit immobile," says Roger Kay, analyst at Endpoint Technologies Associates.

You need to know how well your algorithms perform on unseen data. The best way to evaluate the performance of an algorithm would be to make predictions for new data to which you already know the answers. The second best way is to use clever techniques from statistics called resampling methods that allow you to make accurate estimates for how well your algorithm will perform on new data. In this post you will discover how you can estimate the accuracy of your machine learning algorithms using resampling methods in Python and scikit-learn.

Moving to the right, credit card fraud detection and spam filtering have higher levels of predictability, but current-day systems still generate significant numbers of false positives and false negatives. Consider two of the relatively higher predictability problems mentioned earlier--spam filtering and driverless cars. In contrast, above the frontier, we find that even the best current diabetes prediction systems still generate too many false positives and negatives, each with a cost that is too high to justify purely automated use. On the other hand, the availability of genomic and other personal data could improve prediction accuracy dramatically (long orange horizontal arrow) and create trustworthy robotic healthcare professionals in the future.

Computers and other machines have and will continue to change the way people do business and how we live. Many researchers use the term artificial intelligence (AI) to describe the thinking and intelligent behavior demonstrated by machines. While AI can be helpful to human beings, scientists warn, it can also be a threat. We live with artificial intelligence all around us. A few examples are iPhone's personal assistant Siri, searches on the Internet, and autopilot programs on airplanes.

Worldwide spending on cybersecurity likely topped 75 billion last year, researchers at Gartner estimated, with companies more wary than ever of the risks posed by data breaches and other digital attacks. And along with rising costs, the sheer volume of digital security data has also increased dramatically: IBM estimated in a recent study that the average organization sees more than 200,000 pieces of security event data per day and that more than 10,000 security-related research papers are published every year. "Security researchers are getting hit with a firehose," says Caleb Barlow, vice president of IBM Security. "Once they get done with today, they've got another deluge of data coming tomorrow." To help companies handle that flood of data, IBM says it's training its Watson artificial intelligence platform--previously known for using its natural language processing power to beat humans on Jeopardy--to parse cybersecurity information, from automated network-level threat reports to blog posts from security professionals. According to Barlow, the company hopes to train the system to detect and understand threats to computer systems and to answer questions from human security professionals about incidents they detect on their networks.

How would you perform accurate classification on a very large dataset, by just looking at a sample of it? One of his recent papers is about big data and similarity metrics. In this work Rocco proposes a deterministic method to obtain subsets from Big Data which are a good representative of the inherent structure in the data itself. This allows one to consider only a subset of the entire dataset, still performing at high accuracy if not better than traditional (eg. As you can see, there is always a solution in Big Data.

In the previous recipe "Engage Machine Learning for detecting anomalous behaviors of things", we saw how one can integrate IBM Watson IoT, Apache Spark service, Predictive Analysis service and Real-Time Insights to take timely action before an (unacceptable) event occurs. And in this recipe, we will make use of the data (historical data) produced by the previous recipe to discover the hidden patterns, temperature trend over the days, month and year using Apache Spark SQL, Pandas DataFrame and Jupyter Notebook. Apache Spark SQL is a Spark module for structured data processing. Unlike the basic Spark RDD API, the interfaces provided by Spark SQL provide Spark with more information about the structure of both the data and the computation being performed. Internally, Spark SQL uses this extra information to perform extra optimizations.

This controversial question is argued by many who hold very strong opinions.

Google has built its own computer chip. And this won't be the last. The Internet's most powerful company sent a few shock waves through the tech world yesterday when it revealed that a new custom-designed chip helps run what is surely the future of its vast online empire: artificial intelligence. In building its own chip, Google has taken yet another step along a path that has already remade the tech industry in enormous ways. Over the past decade, the company has designed all sorts of new hardware for the massive data centers that underpin its myriad online services, including computer servers, networking gear, and more. As it created services of unprecedented scope and size, it needed a more efficient breed of hardware to run these services.
