Objective: Using traditional approaches, a Brain-Computer Interface (BCI) requires the collection of calibration data for new subjects prior to online use. Calibration time can be reduced or eliminated e.g.~by transfer of a pre-trained classifier or unsupervised adaptive classification methods which learn from scratch and adapt over time. While such heuristics work well in practice, none of them can provide theoretical guarantees. Our objective is to modify an event-related potential (ERP) paradigm to work in unison with the machine learning decoder to achieve a reliable calibration-less decoding with a guarantee to recover the true class means. Method: We introduce learning from label proportions (LLP) to the BCI community as a new unsupervised, and easy-to-implement classification approach for ERP-based BCIs. The LLP estimates the mean target and non-target responses based on known proportions of these two classes in different groups of the data. We modified a visual ERP speller to meet the requirements of the LLP. For evaluation, we ran simulations on artificially created data sets and conducted an online BCI study with N=13 subjects performing a copy-spelling task. Results: Theoretical considerations show that LLP is guaranteed to minimize the loss function similarly to a corresponding supervised classifier. It performed well in simulations and in the online application, where 84.5% of characters were spelled correctly on average without prior calibration. Significance: The continuously adapting LLP classifier is the first unsupervised decoder for ERP BCIs guaranteed to find the true class means. This makes it an ideal solution to avoid a tedious calibration and to tackle non-stationarities in the data. Additionally, LLP works on complementary principles compared to existing unsupervised methods, allowing for their further enhancement when combined with LLP.

DeepMind is known internationally as a leader in an area of computer science called machine learning. Now senior DeepMind staff are joining forces with UCL's Department of Computer Science to share their knowledge by delivering a state-of-the-art Master's level training module called'Advanced Topics in Machine Learning'. This new module will provide a key component of UCL's Machine Learning Master's programmes and will cover some of the most sophisticated topics in artificial intelligence. The first of these lectures will take place in January 2017. The course focuses on deep learning and reinforcement learning, and will be led by DeepMind's Thore Graepel, who also holds a UCL professorship.

This post is authored by Kristin M. Tolle, Director of Program Management for Advanced Analytics Ecosystem Development and Training at Microsoft. Cortana Intelligence, Microsoft's end-to-end platform for Advanced Analytics, offers a suite of services to solve real world customer problems. The suite has many moving parts – Data Lake, HDInsight (Hadoop), Event Hub, Machine Learning and R – just to name a few, and we realize it may be challenging for some of you to experience first-hand how all these services work together in concert. My team, which is tasked with training our partners to use these services to address their customers' needs, is keenly aware of the breadth of that knowledge surface area. In this blog post, I outline some of the best ways for you to learn about all things Big Data and Advanced Analytics from Microsoft, including many hands-on training options, and also how to stay in the loop on our future offerings.

What makes a cartoon caption funny? As one algorithm found: a simple readable sentence, a negation, and a pronoun--but not "he" or "she." The algorithm went on to pick the funniest captions for thousands of the New Yorker's cartoons, and in most cases, it matched the intuition of its editors. Algorithms are getting much better at understanding language, and we are becoming more aware of this through stories like that of IBM Watson winning the Jeopardy quiz. Google released the word2vec tool, and Facebook followed by publishing their speed optimized deep learning modules.

Lung cancer is one of the most common types of cancer, with nearly 225,000 new cases of the disease expected in the U.S. in 2016. Using a data set of high-resolution scans of lungs provided by the National Cancer Institute, participants will develop artificial intelligence algorithms to accurately determine when lesions in the lungs are cancerous. This will dramatically reduce the false positive rate that prevents low-dose CT scans from being widely used for lung cancer detection. Competition results have the potential to advance our understanding of how all types of cancer develop and spread in the body. They'll also free radiologists to spend more time with patients.

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.

Machine learning has come a long way since Hollywood painted it as shiny robots fueled by artificial intelligence. In the Hollywood version, robots usually end up replacing humans. But today, we're actually using machine learning to supplement many of the things that humans do best. They feel foreign, scientific, and hard to understand. And for many professionals, the phrase still sounds like highly technical jargon.

How can I become a data scientist? A quick search yields a plethora of possible resources that could help -- MOOCs, blogs, Quora answers to this exact question, books, Master's programs, bootcamps, self-directed curricula, articles, forums and podcasts. Their quality is highly variable; some are excellent resources and programs, some are click-bait laundry lists. Since this is a relatively new role and there's no universal agreement on what a data scientist does, it's difficult for a beginner to know where to start, and it's easy to get overwhelmed. Many of these resources follow a common pattern: 1) Here are the skills you need and 2) Here is where you learn each of these.
