Uncovering Genius: Zach Singleton on Preparing Black Male CS Students for Tech Careers

Since 2012, Oakland-based The Hidden Genius Project has been working to provide black male high school students with mentoring and training for careers in science and technology. This year, Uber partnered with The Hidden Genius Project to design a curriculum for black male college computer science students in preparation for technical careers. For Zach Singleton, the product manager for Uber’s Privacy Engineering team, the mission of The Hidden Genius Project hit close to home. Not only had one of his…

Optimizing customized steel products for manufacturers

AutoBarSizer calculated cutting plan with leftovers. Green: reusable remainder (type 2), yellow: reusable remainder (type 1), red: scrap. Credit: Fraunhofer SCAI Companies that process steel usually require customized cutting of steel bars for their products. As a result, steel traders are faced with the challenge of meeting customer-specific requirements while producing as little scrap as possible. That means they have to divide the inventory as efficiently as possible in terms of material. Researchers from the Fraunhofer Institute for Algorithms and…

Luke Skywalker’s hand inspires scientists to create robotic skin

Scientists at the University of Bristol are engineering human skin on artificial robotic muscles that can stretch and bend the tissue just like in the real world. This living and moving skin equivalent represents a much more realistic model of human skin and it could have potential applications for burns patients needing skin grafts. Currently, skin models are flat and static because they are grown on a rigid plastic membrane and there is no laboratory model of moving skin. Now…

Wriggling tadpoles may hold clue to how autism develops — ScienceDaily

You could say Hollis Cline’s lab at The Scripps Research Institute is building better tadpoles. To better understand how humans learn, Cline, PhD, Hahn Professor of Neuroscience and co-chair of the Department of Neuroscience, leads experiments designed to spark learning in tadpole brains. Over the years, her lab’s work with tadpoles has shed light on neuroplasticity — how new experiences flood brain cells with proteins that fuel brain development and learning. Now the lab’s latest study, published in eLife, suggests…

Students create exoskeleton app for patient with muscular dystrophy

MSU students create exoskeleton app for patient with muscular dystrophy. Credit: MSU Zach Smith has Duchenne muscular dystrophy, a genetic disorder marked by progressive muscle degeneration. His lack of muscle control and being in a wheelchair made him a prime candidate for a computer-controlled exoskeleton arm. Talem Technologies gave him an X-Ar exoskeleton that allows him to do many daily tasks, such as drink from a glass and turn on a light switch. Keeping everything level however, proved to be…

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…
