AI at F8 2018: Open frameworks and responsible development | Engineering Blog | Facebook Code

Artificial intelligence has the potential to transform lives, creating new digital experiences while safeguarding our existing online interactions. Balancing rapid and responsible progress requires foundational investment, as well as a strategic vision for how to build and use this evolving technology. On Day 2 of F8 — Facebook’s annual developer’s conference — we detailed the company’s approach to advancing AI through our open development frameworks and collaborative relationship with the wider AI community. Our keynote speakers, including Facebook’s Chief Technology…

Advancing state-of-the-art image recognition with deep learning on hashtags | Engineering Blog | Facebook Code

Image recognition is one of the pillars of AI research and an area of focus for Facebook. Our researchers and engineers aim to push the boundaries of computer vision and then apply that work to benefit people in the real world — for example, using AI to generate audio captions of photos for visually impaired users. In order to improve these computer vision systems and train them to consistently recognize and classify a wide range of objects, we need data…

Uplift Modeling in Display Remarketing

At Wayfair, the data science teams collaborate with other partner teams to translate business problems into analytical frameworks, leverage data and machine learning to make robust predictions and recommendations, and build engineering architecture to scale up machine learning solutions. In a recent machine learning seminar at Northeastern University in Boston, Data Science Manager Jen Wang gave an overview of the team’s structure and a few examples of machine learning models used to solve business challenges at Wayfair. The final part…

Engineering Ethics Blog: Vision Zero: Realistic Goal or Illusion?

About a week ago, I was involved in a very minor collision that slightly dented my car’s rear bumper cover.  When I took the car to a body shop to get an estimate for the repair, I picked up a magazine published by the American Automobile Association and read about something called Vision Zero.  Vision Zero is a program aimed at reducing auto-related fatalities to the point that nobody dies (involuntarily, anyway) in a car accident anymore.  It originated with…

Artificial intelligence helps soldiers learn many times faster in combat

Army researchers and their academic partners find artificial intelligence techniques that allows US soldiers to learn 13 times faster. Credit: US Army illustration New technology allows U.S. Soldiers to learn 13 times faster than conventional methods and Army researchers said this may help save lives. At the U.S. Army Research Laboratory, scientists are improving the rate of learning even with limited resources. It’s possible to help Soldiers decipher hints of information faster and more quickly deploy solutions, such as recognizing…

Impact of a real-world intervention offers a lesson for other cities — ScienceDaily

A study by researchers from the National University of Singapore (NUS) and the University of Sao Paulo revealed that a beltway constructed to divert heavy-duty diesel vehicles traffic in the Brazilian city of Sao Paulo has reduced public health damage associated with exposure to diesel. The positive health outcomes of the intervention could guide the formulation of similar transport polices in other cities, where humans and diesel vehicles reside and transit in close proximity. In densely populated cities like Sao…

MacOS monitoring the open source way

Let’s say a machine in your corporate fleet gets infected with malware. How would you detect it? How could you find out what happened on the machine? What did the malware do? Did it steal your browser’s passwords? What network connections did the malware make? Was it looking for crypto currency? By having good telemetry and a good host monitoring solution for your machines you can collect the context necessary to answer these important questions. Proper host monitoring on macOS…

A step toward faster, more accurate breast cancer detection

Credit: University of California – Berkeley Over the course of her lifetime, a woman has a one in eight chance of developing breast cancer. The earlier the cancer is detected, the more likely bad luck can turn to good. Now new technology being developed by UC Berkeley engineers could dramatically improve the speed and accuracy of early breast cancer detection through the use of microfluidics. Mechanical engineering professor Lydia Sohn and her research group have devised a totally new…

Accelerating Deep Neuroevolution: Train Atari in Hours on a Single Personal Computer

By Felipe Petroski Such, Kenneth O. Stanley and Jeff Clune We recently published an article announcing five papers on deep neuroevolution, including the discovery that genetic algorithms can solve deep reinforcement learning problems as well as popular alternatives, such as deep Q-learning and policy gradients. That work follows on Salimans et al. 2017, which showed the same for evolution strategies (ES), another neuroevolution algorithm. We further described how ES can be improved by adding exploration in the form of a…

Digital Advertising and Causal Impact: Using Data Science to Power a Delightful Customer Experience

As data scientists, we face a variety of problem types. One of our critical challenges is identifying the proper methodological approach to solve each problem. By doing this, we avoid force-fitting the wrong tool to solve a problem, and we avoid having to reformulate a question to fit a specific method. One way to characterize problems is by the type of results that answer the question at hand. For many data science questions, we can use predictive frameworks. Tasks such…
