Linear algebra is a field of applied mathematics that is a prerequisite to reading and understanding the formal description of deep learning methods, such as in papers and textbooks. Generally, an understanding of linear algebra (or parts thereof) is presented as a prerequisite for machine learning. Although important, this area of mathematics is seldom covered by computer science or software engineering degree programs. In this post, you will discover the crash course in linear algebra for deep learning presented in the de facto textbook on deep learning.

A robotic hand that can translate words into sign language gestures for deaf people has been created by scientists. Named Project Aslan, the 3D-printed hand costs as little as £400 ($560) to make and interprets both written text and spoken words. The device communicates through'fingerspelling', a type of sign language where words are spelled out letter-by-letter through separate gestures on a single hand. The robot, which will be ready in five years, could one day be carried around in a rucksack, scientists say. It could help some of the 70 million worldwide who are deaf or hard of hearing to communicate with people who don't know sign language.

If you are a developer, a random tech interested person or you don't have anything to do with tech, you must have heard phrase machine learning many many times in past few years. You can read about it on blogs, in newspapers, on TV and even when going to the supermarket. It looks like machine learning is one of those buzzwords that is buzzing and buzzing. One reason is that there are some people, companies that are using machine learning for solving cool and serious problems. They are solving things that were not solvable before, taking a different approach to all sorts of topics.

Businessman on blurred background using digital artificial intelligence (AI) interface 3D rendering. An artificial intelligence (AI) and Blockchain start-up with backing from Harrisburg University in Pennsylvania is developing a completely new way of utilizing and processing data by integrating AI and "smart logic" into every bit of data. The goal is to build what is described as an "AI Superhighway" according to the tech protagonists with the vision behind the project. Essentially, the proposition goes that by embedding every piece of data with artificial intelligence, otherwise "dumb data", which requires an application to become useful, becomes valuable and "smart." This means the "AI Thought" attaches to data allows the digital information to act on its own.

Artificial Intelligence seems to be reinforcing gender stereotypes. In 2016, a university professor from Virginia noticed that the image recognition system he was working on often associated picture of kitchens with women. Intrigued, he and his colleagues tested large collections of photos used to train this kind of software. What they discovered was shocking. The software's depiction of common activities showed a definite gender bias.

The Arcade Learning Environment (ALE) is an evaluation platform that poses the challenge of building AI agents with general competency across dozens of Atari 2600 games. It supports a variety of different problem settings and it has been receiving increasing attention from the scientific community, leading to some high-profile success stories such as the much publicized Deep Q-Networks (DQN). In this article we take a big picture look at how the ALE is being used by the research community. We show how diverse the evaluation methodologies in the ALE have become with time, and highlight some key concerns when evaluating agents in the ALE. We use this discussion to present some methodological best practices and provide new benchmark results using these best practices. To further the progress in the field, we introduce a new version of the ALE that supports multiple game modes and provides a form of stochasticity we call sticky actions. We conclude this big picture look by revisiting challenges posed when the ALE was introduced, summarizing the state-of-the-art in various problems and highlighting problems that remain open.

Ensemble methods -- particularly those based on decision trees -- have recently demonstrated superior performance in a variety of machine learning settings. Specifically, Random Forest (RF) was found to outperform >100 other methods in several manuscripts, and gradient boosting trees have been a crucial component of several recent Kaggle competition victories. Building off these successes and recent advances in sparse learning and random matrix theory, we propose a novel ensemble tree method called "Randomer Forest" (RerF). The key intuition behind RerF is that we can use sparse linear combinations at each decision node rather than just one feature (as in RF) or all of them (as in Rotation Forests). RerF significantly outperforms other methods on a standard benchmark suite containing 105 problems with varying dimension, sample size, and number of classes. Moreover, we provide an implementation that scales as or more efficiently than other available packages. Via a combination of basic principles, theory, and extensive numerical experiments, we demonstrate why, when, and how RerF achieves its performance properties.

I spend a lot of time in the air, travelling around the globe spreading the word about On-Demand Education Marketplace, or ODEM.IO. One of the questions I'm asked most often on my business trips is "How will blockchain technology help ODEM to improve education?" My answer: Blockchain gives us the opportunity to go big. Blockchain, automated smart contracts and artificial intelligence enable us to provide solutions to global problems in education such as accessibility, cost and the removing the inefficiencies caused by intermediaries. For students the result is improved access to a learning that better prepares them for the changing demands of the job market.

Artificial intelligence and machine learning are making their way into all aspects of our lives and businesses. Every time you ask Amazon's Alexa for the weather forecast or book a car through Lyft, you're benefitting from the power of AI. Entrepreneurs, in particular, are seeing their companies transformed by these technologies, and that trend will only continue in the coming years. One obvious opportunity for leveraging AI and machine learning in your business lies in teaching new employees about their responsibilities and the company. Many businesses already use online training programs and simulators when onboarding new employees.

In the wake of the Parkland school shooting, President Trump is meeting with video game executives and members of congress to discuss the role of simulated violence and the impact on America's youth. They called it the "Filthy 15." Fifteen songs from 15 bands or artists that the Parents Music Resource Center found offensive due to explicit content. The PMRC's leaders were Susan Baker, wife of then-Treasury Secretary James Baker, and Tipper Gore. Gore was wife of then-Sen. The acts in question were Prince, AC/DC, Cyndi Lauper, Madonna, Def Leppard, Motley Crue, Black Sabbath, Sheena Easton and Vanity.
