Transforming Financial Forecasting with Data Science and Machine Learning at Uber

We previously highlighted some of the presentations delivered during our second annual Uber Technology Day. In this article, engineering senior software engineer and Uber Tech Day presenter Chunyan Song discusses how we apply data science and machine learning in our financial planning platforms. As of 2018, Uber’s ridesharing business operates in more than 600 cities, while the Uber Eats food delivery business has expanded to more than 250 cities worldwide. The gross booking run rate for ridesharing hit $37 billion…

3-D printing achieves more accurate and precise physical models from patient imaging data

Credit: Mary Ann Liebert, Inc., publishers Prior to performing a medical procedure, physicians are increasingly relying on access to 3-D printed models created using patient-specific medical data. Unfortunately, current 3-D data processing workflows can be extremely time consuming, and frequently, the resulting 3-D-printed models fail to accurately depict the anatomical details of interest. Motivated by these inherent limitations, an international team of researchers describes a rapid method for creating extremely detailed physical models directly from volumetric data stacks in an…

New kinematics for customized, high-precision milling

Machining robot Flexmatik. Credit: Fraunhofer IFAM Manufacturers generally must offer high-quality products at low prices in order to remain competitive. Three Fraunhofer Institutes are therefore working on the next generation of industrial robots which will facilitate cost-effective production processes. The researchers are focusing on developing a new kinematics for milling lightweight materials, metals, and steels. The aim: achieving a production tolerance of just 0.1 millimeters all over the robot workspace starting with the very first component. More and more consumers…

A factory to go

A fully automated production line can be housed inside a 20-foot ISO container, which a heavy truck can transport quickly to wherever it is needed. Medical products can be manufactured in close proximity to a hospital, for instance. Fraunhofer researchers teamed up with partners to develop this mobile factory in the scope of CassaMobile, an…

New form of ‘active matter’ driven by the dissolution of droplets of an ionic liquid — ScienceDaily

Researchers from Tokyo Metropolitan University have observed the formation of holes that move by themselves in droplets of ionic liquids (IL) sitting inside water-ethanol mixtures. This curious, complex phenomenon is driven by an interplay between how ionic liquids dissolve, and how the boundary around the droplet fluctuates. Self-driven motion is a key feature of active matter, materials that use ambient energy to self-propel, with potential applications to drug delivery and nano-machine propulsion. Most people are familiar with how things mix…

Spotify ML Day – July 9th 2018 – Stockholm

We are happy to announce the first Spotify Machine Learning Day taking place Monday, July 9th, 2018, 9:30 AM – 5:30 PM at Spotify, Regeringsgatan 19, Stockholm, Sweden. The event brings together leading researchers from the industry on machine learning topics related to music understanding and generation, recommendation, and counterfactual evaluation. We invite anyone interested in learning more about the theory and impact of machine learning to attend.   Agenda of the day   Opening Keynote –  François Pachet, SpotifyUsing AI…

Testing the GPS behind tomorrow’s self-driving money – Engineering Blog – Wealthfront

Recently, Wealthfront CEO Andy Rachleff shared the following vision at the CB Insights Future of Fintech conference: “Our vision is to deliver a service where you direct deposit your paycheck with us. We automatically pay your bills. We automatically top off your emergency fund, and then route money to whatever account is the most ideal for your particular goals, whether they’re at Wealthfront or elsewhere.” Soon after, some aptly described this as “self-driving money.” Here’s some good news: we are…

Delivering a Serverless API in 10 minutes using Workers

In preparation for Chrome’s Not Secure flag, which will update the indicator to show Not Secure when a site is not accessed over https, we wanted people to be able to test whether their site would pass. If you read our previous blog post about the existing misconceptions around using https, and preparing your site, you may have noticed a small fiddle, allowing you to test which sites will be deemed “Secure”. In preparation for the blog post itself, one…

Supercomputers help design mutant enzyme that eats plastic bottles

Supercomputers helped study the binding of a plastic-degrading enzyme, PETase, which could lead to developing industrial-scale plastic recycling for throw-away bottles and carpet. Electrostatic potential distribution of PETase structure shown. Credit: Lee Woodcock A dump truck’s worth of plastic empties into the ocean every minute. Worldwide, humankind produces over 300 million tons of plastic each year, much of which is predicted to last centuries to millennia and pollutes both aquatic and terrestrial environments. PET plastic, short for polyethylene terephthalate, is…

Laser-made aircraft parts a breakthrough for industry
