Scientists have developed a new artificial intelligence software that can turn any smartphone into an eye-tracking device. Eye-tracking technology - which can determine where in a visual scene people are directing their gaze - has been widely used in psychological experiments and marketing research, but the required pricey hardware has kept it from finding consumer applications. In addition to making existing applications of eye-tracking technology more accessible, the system developed by researchers at Massachusetts Institute of Technology (MIT) and University of Georgia may enable new computer interfaces or help detect signs of incipient neurological disease or mental illness. "Since few people have the external devices, there is no big incentive to develop applications for them," said Aditya Khosla, an MIT graduate student. "Since there are no applications, there's no incentive for people to buy the devices. We thought we should break this circle and try to make an eye tracker that works on a single mobile device, using just your front-facing camera," he said.

The traditional definition of artificial intelligence is the ability of machines to execute tasks and solve problems in ways normally attributed to humans. Some tasks that we consider simple--recognizing an object in a photo, driving a car--are incredibly complex for AI. Machines can surpass us when it comes to things like playing chess, but those machines are limited by the manual nature of their programming; a 30 gadget can beat us at a board game, but it can't do--or learn to do--anything else. This is where machine learning comes in. Show millions of cat photos to a machine, and it will hone its algorithms to improve at recognizing pictures of cats.

The TensorFlow project is bigger than you might realize. The fact that it's a library for deep learning, and its connection to Google, has helped TensorFlow attract a lot of attention. Cool stuff, but--especially for someone hoping to explore machine learning for the first time--TensorFlow can be a lot to take in. Let's break it down so we can see and understand every moving part. We'll explore the data flow graph that defines the computations your data will undergo, how to train models with gradient descent using TensorFlow, and how TensorBoard can visualize your TensorFlow work. The examples here won't solve industrial machine learning problems, but they'll help you understand the components underlying everything built with TensorFlow, including whatever you build next!

This free evening talk will explore the fields of Deep Learning and Computer Vision, using lie detection from video as an example. Nick studied Computer science at Imperial College before moving to the industry to work as a Data Scientist. He is active in the London startup scene and is interested in the role technology plays in our emotional wellbeing. He is an advocate of designing for happiness.

Learning needs to be less like memorization, and more like… Angry Birds. Half of school dropouts name boredom as the No. 1 reason they left. The blog is about why the future of education will be about flipping our current model on its head and about how key exponential technologies like AI, VR and gamification are going to drive a revolution in education. In the traditional education system, you start at an "A." And every time you get something wrong, your score gets lower and lower.

Although numeric data is easy to work with in Python, most knowledge created by humans is actually raw, unstructured text. By learning how to transform text into data that is usable by machine learning models, you drastically increase the amount of data that your models can learn from. In this tutorial, we'll build and evaluate predictive models from real-world text using scikit-learn.

Organizations create style guides to capture the rationale of their design decisions and help other teams build great experiences. You might have read gov.UK's service manual or the U.S. Digital Services Playbook. I wanted to do the same for chatbots build on the Facebook's messenger platform. At Sure, we are creating an online assistant that helps you find food and drinks that are better for yourself and the planet. It is still very early days for bots, so I wanted to take the opportunity to share some of our early learnings.

"I think being radical is the only way of doing things, because slow iteration doesn't really work." Claned Co-founder Vesa Perala believes that instead of attempting to retrofit technology to out-dated educational systems, EdTech start-ups should be helping to write a new rulebook. "Our pitch pretty much begins with education reform. The starting point is that the Finnish schooling system might be perceived as being the best in the world, but we're still overhauling it," he says. For the past 3 years, Claned has been in what he describes as semi-stealth mode, focusing on developing a robust artificial intelligence system that uses machine-learning algorithms to map out what factors most impact individual learning.

Even research which is conducted within the university setting is increasingly pushing up against new ethical frontiers in the creation of machine learning algorithms based on vast pools of human-created training data. For example, several researchers I spoke with mentioned situations where colleagues had taken large datasets licensed to the university for strictly non-commercial use or collected from human subjects for strictly academic research and used them to construct large machine learning computer models. These models were then licensed from the university to the faculty member's private startup, where they were then used for commercial gain. In at least some cases, protected human subjects data was used to create a computer model for academic research, which was approved by IRB, but that model was then allegedly subsequently licensed by the university for commercial use to the faculty member's startup. None of the researchers were privy to whether IRB had approved the commercial licensing or if that occurred without IRB knowledge and they argued that the very nature of a machine learning model deidentifies such data to the point that it should no longer be considered human subjects data.
