Set of neurons in spinal cord help transmit a light-touch signal from skin to brain — ScienceDaily

Light touch plays a critical role in everyday tasks, such as picking up a glass or playing a musical instrument. The sensation is also an essential part of the body’s protective defense system, alerting us to objects in our environment that could cause us to fall or injure ourselves. In addition, it is part of the detection system that has evolved to protect us from biting insects, such as those that cause malaria and Lyme disease, by eliciting a feeling…

Science at Uber: Making a Real-world Impact with Data Science

At Uber, we take advanced research work and use it to solve real world problems. In our  Science at Uber video series, Uber employees talk about how we apply data science, artificial intelligence, machine learning, and other innovative technologies in our daily work. As a graduate student at UC Berkeley, Suzette Puente, Data Science Manager, used statistics to understand and explain animal mobility patterns. At Uber, Suzette and her team apply similar techniques to forecast traffic patterns. By leveraging spatiotemporal…

Build and Test Workers Faster with Wrangler CLI 1.2.0

As part of my internship on the Workers Developer Experience team, I set out to polish the Wrangler CLI for Cloudflare Workers. If you’re not familiar with Workers, the premise is quite simple: Write a bit of Javascript that takes in an HTTP request, does some processing, and spits out a response. The magic lies in where your Workers scripts run: on Cloudflare’s edge network, which spans 193 cities in more than 90 countries. Workers can be used for nearly…

Towards an ‘orrery’ for quantum gauge theory — ScienceDaily

The interaction between fields and matter is a recurring theme throughout physics. Classical cases such as the trajectories of one celestial body moving in the gravitational field of others or the motion of an electron in a magnetic field are extremely well understood, and predictions can be made with astonishing accuracy. However, when the quantum character of the particles and fields involved has to be factored in explicitly, then the situation quickly becomes rather complex. And if, in addition, the…

Should Social Media Be Regulated?

Last month, the youngest U. S. Senator, Josh Hawley, a freshman Republican from Missouri, filed a bill called the Social Media Addiction Reduction Technology (SMART) Act.  The purpose of the act is to do something about the harmful effects of addiction to social media. What would the bill do?  I haven’t read it, but according to media reports it would change the ways companies like Facebook, Twitter, and Google deal with their customers.  The open secret of social media is…

A scalable system for content classification

Eileen Li | Software Engineer, Knowledge Content understanding is at the core of any great recommendation system. By knowing what each Pin is about, Pinterest can connect Pinners with the most relevant and inspiring content that best matches their interests. The Interest Taxonomy captures popular concepts that appear within Pinterest and organizes them into a structured hierarchy. This highly-curated taxonomy tree currently has 10 levels of granularity, with 24 top-level concepts such as “women’s fashion” and “DIY crafts” and tens…

Cheng named Faculty Fellow for Research and Strategic Initiatives

Jianlin Cheng was named Faculty Fellow for Research and Strategic Initiatives on Thursday. On Thursday, Mizzou Engineering Dean Elizabeth Loboa announced the selection of Jianlin Cheng, William and Nancy Thompson Missouri Distinguished Professor of Electrical Engineering & Computer Science, as the College of Engineering’s Faculty Fellow for Research and Strategic Initiatives. Cheng has been the recipient of numerous competitive grants from the National Science Foundation, National Institutes of Health, Department of Energy and the Department of Education. He has been…

New advances in natural language processing to better connect people

Natural language understanding (NLU) and language translation are key to a range of important applications, including identifying and removing harmful content at scale and connecting people across different languages worldwide. Although deep learning–based methods have accelerated progress in language processing in recent years, current systems are still limited when it comes to tasks for which large volumes of labeled training data are not readily available. Recently, Facebook AI has achieved impressive breakthroughs in NLP using semi-supervised and self-supervised learning techniques,…

Science at Uber: Applying Artificial Intelligence at Uber

At Uber, we take advanced research work and use it to solve real world problems. In our  Science at Uber video series, Uber employees talk about how we apply data science, artificial intelligence, machine learning, and other innovative technologies in our daily work. Zoubin Ghahramani, Chief Scientist at Uber, understands that movement requires intelligence, and draws a parallel between biological and artificial systems. His organization, Uber AI, develops artificial intelligence to advance Uber’s core business needs. Research into reinforcement learning,…
