No Coding Required: Training Models with Ludwig, Uber’s Open Source Deep Learning Toolbox

Machine learning models perform a diversity of tasks at Uber, from improving our maps to streamlining chat communications and even preventing fraud. In addition to serving a variety of use cases, it is important that we make machine learning as accessible as possible for experts and non-experts alike so it can improve areas across our business. In this spirit, we built Ludwig, an open source, deep learning toolbox built on top of TensorFlow that allows users to train and test…

Development of durable MTJ under harsh environment for STT-MRAM at 1Xnm technology node

Figure 1: (a) The developed MTJ structure in this study compared with (b) the conventional MTJ structure. Credit: Tohoku University Researchers at Tohoku University have announced the development of a new magnetic tunnel junction, by which the team has demonstrated an extended retention time for digital information without an increase of the active power consumption. Non-volatile memories are essential constituents in integrated circuits, because they can offer low power consumption. Among proposed non-volatile memories, spin-transfer-torque magnetoresistive random access memory (STT-MRAM)…

Student creates portable wallet to keep medication cool after being inspired by girlfriend’s story

Credit: Loughborough University A student from Loughborough University has designed a portable wallet to keep medication cool after being inspired by his girlfriend who was diagnosed with Multiple Sclerosis (MS). Bish Clow, 22, who studies Product Design and Technology, has created Chill—a flexible insulated pouch to store medication at refrigerator temperature. The aim of the product is to give people the freedom to enjoy trips away from home without worrying about how to keep their medication cold. Bish first came…

Making the ‘human-body internet’ more effective

Experiment setup to understand how characteristics of human body communication can be improved. Credit: Dairoku Muramatsu & Yoshifumi Nishida, Source: Equivalent Circuit Model Viewed from Receiver Side in Human Body Communication Wireless technologies such as Wi-Fi and Bluetooth have made remote connectivity easier, and as electronics become smaller and faster, the adoption of “wearables” has increased. From smart watches to implantables, such devices interact with the human body in ways that are very different from those of a computer. However,…

the view from the front lines

Growing up in the age of technology has made it too easy for me to take the presence of the Internet for granted. It’s hard to imagine not being able to go online and connect with anyone in the world, whether I’m speaking with family members or following activists planning global rallies in support of a common cause. I find that as I forget the wonder of being connected, I become jaded. I imagine that many of you reading this…

Materials informatics reveals new class of super-hard alloys — ScienceDaily

A new method of discovering materials using data analytics and electron microscopy has found a new class of extremely hard alloys. Such materials could potentially withstand severe impact from projectiles, thereby providing better protection of soldiers in combat. Researchers from Lehigh University describe the method and findings in an article, “Materials Informatics For the Screening of Multi-Principal Elements and High-Entropy Alloys,” that appears today in Nature Communications. “We used materials informatics — the application of the methods of data science…

Expansion microscopy and virtual reality illuminate new ways to prevent and treat disease

Brendan Gallagher, a biological sciences graduate student at Carnegie Mellon University, uses virtual reality to examine 3D biological data gathered using expansion microscopy. Credit: Carnegie Mellon University A combined research team from Carnegie Mellon University and Benaroya Research Institute at Virginia Mason is pairing a nanoscale imaging technique with virtual reality (VR) technology to create a method that allows researchers to “step inside” their biological data. By combining the technique, called expansion microscopy, with VR, scientists will be able to…

Setting the Pace: A Q&A with Jennifer Anderson, Senior Director of Engineering at Uber

As Senior Director of Engineering for Uber’s Product Platform, Jennifer Anderson leads the teams responsible for building and operating the underlying business platforms that help power Uber’s portfolio of products such as rideshare and Uber Eats food delivery. Jennifer’s responsibilities also include the engineering tools and platforms for data analytics, machine learning, customer care, marketing, and business communications. Making this large portfolio more challenging, Jennifer leads teams based in offices from Amsterdam to Bangalore to San Francisco. Jennifer’s education and…

Protecting Project Galileo websites from HTTP attacks

Yesterday, we celebrated the fifth anniversary of Project Galileo. More than 550 websites are part of this program, and they have something in common: each and every one of them has been subject to attacks in the last month. In this blog post, we will look at the security events we observed between the 23 April 2019 and 23 May 2019. Project Galileo sites are protected by the Cloudflare Firewall and Advanced DDoS Protection which contain a number of features…

Soon, air pollution could be measured on every street corner

The prototype consists of a sensor connected to a box which both shows the emissions levels in real time, and saves the results over time. Credit: Mia Halleröd Palmgren/Chalmers University of Technology Air pollution is responsible for 550,000 premature deaths a year in Europe and 7 million worldwide, according to the WHO. Measuring it can be a challenge, however, as the equipment tends to be large and expensive. But soon, this may change, thanks to a small, optical nanosensor developed…
