The Perceptron algorithm is the simplest type of artificial neural network. It is a model of a single neuron that can be used for two-class classification problems and provides the foundation for later developing much larger networks. In this tutorial, you will discover how to implement the Perceptron algorithm from scratch with Python.

This section provides a brief introduction to the Perceptron algorithm and the Sonar dataset to which we will later apply it.

Bullying has recently become a hot topic of conversation, particularly in schools. But of course, it's been an issue for decades, if not millennia, probably because it's human nature to pick on others who are seen as weak or different. Sadly, a new study suggests that we may not limit our bullying to other humans. In the dawning age of artificial intelligence–like the kind found in self-driving cars–we may begin to bully software. The study was conducted by Goodyear and the London School of Economics.

The growing number of services that run machine learning algrithms under the hood will now be able to tap the popular open-source database Redis' capabilities much more easily than before. Typically used to cache applications' most frequently accessed information, Redis has received a new extension today that brings integration with Spark ML. Organizations that employ that framework to power their machine learning projects can now easily load models into Redis to improve their performance. Initial benchmark tests indicate that the system provides five to 10 times lower latency than a standard Spark implementation when performing certain tasks such as categorizing records. The assessment was carried out by Redis Labs Inc., the startup behind the new module and the database's main commercializer.

Specifically designed in the context of big data in our research lab, the new and simple strong correlation synthetic metric proposed in this article should be used, whenever you want to check if there is a real association between two variables, especially in large-scale automated data science or machine learning projects. Use this new metric now, to avoid being accused of reckless data science and even being sued for wrongful analytic practice. In this paper, the traditional correlation is referred to as the weak correlation, as it captures only a small part of the association between two variables: weak correlation results in capturing spurious correlations and predictive modeling deficiencies, even with as few as 100 variables. In short, our strong correlation (with a value between 0 and 1) is high (say above 0.80) if not only the weak correlation is also high (in absolute value), but when the internal structures (auto-dependencies) of both variables X and Y that you want to compare, exhibit a similar pattern or correlogram. Yet this new metric is simple and involves just one parameter a (with a 0 corresponding to weak correlation, and a 1 being the recommended value for strong correlation).

Batch jobs are the lifeblood for thousands of businesses--many of which run millions of batch jobs every year. Unfortunately, managing these high volumes of batch jobs has become a huge nightmare: numerous errors require a large amount of resources to validate and isolate the problems. Even then, batch jobs still run into unexpected outages, while Service Level Agreement (SLA) violations threaten the proper operation of the business. This webinar demonstrates how ignio, the world's leading cognitive system, has been helping customers tackle this complex problem. We share real world examples on how ignio is implemented and highlight the lessons learned from these implementations.

Israeli artificial intelligence startup Voyager Labs has emerged from stealth mode with customers, use cases, and $100 million in funding. Voyager Labs has raised the funds from prominent investors including Sir Ronald Cohen, Lloyd Dorfman, OCAPAC Holding Company, and Horizons Ventures to help finance the company's next generation solutions for the financial and e-commerce markets. The company has 90 employees at its R&D center in Hod Hasharon and offices in New York, Washington and London. Founded in 2012, Voyager Labs has developed an artificial intelligence engine that combines expert systems with deep-learning algorithms and is capable of extracting dynamic, real-time, and tailored insights into human behavior by analyzing massive amounts of publicly available unstructured data. Voyager Labs was founded by CEO Avi Korenblum, who served in the Israeli intelligence community for 20 years.

People who use Facebook live longer, according to a new study. Using the site to stay in touch with people appears to suggest that using the site is associated with living longer. Scientists have long known that people have stronger social networks and relationships also tend to live longer. The new study shows that the same is true of the online world. "Interacting online seems to be healthy when the online activity is moderate and complements interactions offline," said author William Hobbs in a statement.

Apple is trying to introduce wireless charging into the next iPhone, according to reports. Rumours have long swirled around the iPhone 8 – even before the iPhone 7 was released this year. Reports have suggested that Apple is planning a major redesign for the new handset, which will mark the tenth anniversary of the iPhone, which might include an entirely glass body and a screen that takes up all of the front of the phone. And new reports suggest that Apple is currently exploring the possibility of adding wireless charging modules to the next phone, too. That would mean that it would just need to be set down on a special surface to charge it – in keeping with Apple's commitment to keep moving towards a wireless future, which it stressed when it dropped the headphone jack from the iPhone.

Apple revealed its fourth quarter financial results during a conference call with investors on Tuesday, but perhaps the most interesting narrative -- aside from the company's first annual revenue decline since 2001 -- was the tech giants avowed focus on machine learning. "Today, machine learning drives improvement in countless features across our products," Apple CEO Tim Cook boasted during his initial remarks. Cook then offered a state of machine learning at Apple, by running down areas where machine learning is already helping to improve the iPhone user experience, noting that machine learning "enables the proactive features in iOS 10, and that cameras employ it in face recognizing software. Machine learning is also a key aspect of Apple's fitness offerings. "Machine learning continually helps Siri get smarter in areas, including understanding natural language," Cook added.
