Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

Hyperparameter optimization is a common problem in machine learning. Machine learning algorithms, from logistic regression to neural nets, depend on well tuned hyperparameters to reach maximum effectiveness. Different hyperparameter optimization strategies have varied performance and cost (in time, money, and compute cycles.) So how do you choose? Evaluating optimization strategies is non-intuitive.

Hi there, my name is Harrison and I frequently do Python programming tutorials on PythonProgramming.net and YouTube.com/sentdex. I do my best to produce tutorials for beginner-intermediate programmers, mainly by making sure nothing is left to abstraction and hand waving. The most recent series is an in-depth machine learning course, aimed at breaking down the complex ML concepts that are typically just "done for you" in a hand-wavy fashion with packages and modules. The machine learning series is aimed at just about anyone with a basic understanding of Python programming and the willingness to learn. If you're confused about something we're doing, I can either help, or point you towards a tutorial that I've done already (I have about 1,000) to help.

Meet Jill Watson, a first-time teaching assistant at Georgia Tech assigned to moderate an online forum for a computer science class. Jill was 1 of 9 TAs assigned to help answer questions about coursework and projects from the 300 students enrolled in the advanced course. During the first few weeks in January, Jill really struggled. This was Knowledge-Based Artificial Intelligence, after all, a course with the goal to "build AI agents capable of human-level intelligence and gain insights into human cognition." It was also a requirement for graduate students to earn their master's degree.

First dates can be a nerve-wracking experience, filled with unease and uncertainty over whether or not the other person is interested. But new technology that could help clear up at least some of the mystery surrounding such dates might be on its way. An'emotion detector' has been created which researchers claim will be able to tell whether or not a person finds you attractive almost instantly. An'emotion detector' concept has been designed that can tell if a person finds you attractive on the first date by measuring skin and heart rate responses and a pupil-dilation measure. Researchers at the University of Lancaster were inspired to make the device by a gadget featured in the 1982 sci-fi fantasy film'Blade Runner'.

Unstructured data is the most prevalent form of information on the planet. It exists in our e-mails, surveys, social media accounts, call center logs, etc. With a strong text analytics strategy in place, companies can get critical information from this data to drive better business decisions.

BigML Spring 2016 release is here! GMT 02:00) for a FREE live webinar to learn about the latest and greatest version of BigML. We'll be focusing exclusively on WhizzML, a new domain-specific language that lets you automate Machine Learning workflows, implement high-level Machine Learning algorithms, and share them with others. WhizzML stands to make a big difference not only in how developers conceive of and implement smart applications, but also how analysts and scientists reduce the burden of repetitive analyses.

Logistic Regression is one of the most powerful classification methods within machine learning and can be used for a wide variety of tasks. Think of pre-policing or predictive analytics in health; it can be used to aid tuberculosis patients, aid breast cancer diagnosis, etc. Think of modeling urban growth, analysing mortgage pre-payments and defaults, forecasting the direction and strength of stock market movement, and even predicting sport outcomes. Reading all of this, the theory[1] of Maximum Entropy Classification might look difficult. In my experience, the average Developer does not believe they can design a proper Maximum Entropy / Logistic Regression Classifier from scratch. I strongly disagree: not only is the mathematics behind is relatively simple, it can also be implemented with a few lines of code.

Soldiers are expected to carry heavy packs across rough terrain, sometimes under fire. Now engineers have created a flexible exosuit designed to make their lives slightly easier because it reduces the energy cost of walking when carrying heavy load. The textile suit, using cables and motors, could also be used by hikers and emergency professionals who are first on the scene of an incident. Unlike the exosuits seen in superhero films, engineers at Harvard University used fabric to build their suit. By comparison, rigid exoskeletons are heavier and can interfere with the natural movement of the joints, causing the wearer to change the way they walk.
