In a study published 20 January in IEEE Access, a Japanese research team showed that harnessing radio units on parked cars results in efficient data transmission, all while keeping radio units close to where people are. The team proposed a crowd-sourcing approach, in combination with a monetary or non-monetary incentive, which could be used to get drivers to participate.
With their approach, radio units are charged via the car battery and can be activated when the car is parked. When a crowd-sourced radio unit is available, it establishes a wireless mobile front-haul link with a neighboring distribution unit and starts working to transmit data to nearby phones.
The California Institute of Technology said on Wednesday that it won a $1.1 billion jury verdict in a patent case against Apple (AAPL.O) and Broadcom (AVGO.O).
In a case filed in federal court in Los Angeles in 2016, the Pasadena, California-based research university alleged that Broadcom wi-fi chips used in hundreds of millions of Apple iPhones infringed patents relating to data transmission technology.
Just as Amazon was basking in the news of a massive earnings win, the tech giant quietly published — as it always does — its latest transparency report, revealing a slight dip in the number of government demands for user data.
It’s a rarely seen decline in the number of demands received by a tech company during a year where almost every other tech giant — including Facebook, Google, Microsoft and Twitter — all saw an increase in the number of demands they receive. Only Apple reported a decline in the number of demands it received.
Facial recognition, a controversial technology that can identify individuals by scanning and analyzing their features in real time, is coming to college campuses across the US.
Some colleges see the technology as a way to increase safety in dorms and keep expelled students, former employees, registered sex offenders, and other unauthorized people from setting foot on campus.
But the digital rights group Fight for the Future says the risks outweigh the benefits — and they’ve unveiled a new “scorecard” to grade which schools are weighing those risks appropriately.
“If we don’t speak out, soon every campus could be equipped with invasive technology that monitors everything we do, including who students hang out with and what they do outside of class,” the group’s website says. “It’s time to stop facial recognition on campus before we have no liberties left!”
Skeletons are fundamental tools for teaching anatomy, as well as researching human diversity. Understanding human variation can also help a variety of researchers and clinicians. In addition to forensic science, for instance, dentists can use data about cranial variation to improve the fit of dental implants; plastic surgeons can review studies of the average ear or nose for specific populations to help reconstruct a face after an injury; researchers can create databases to study bone abnormalities; and prosecutors have used prints of human bones in courts to illustrate how a person died.
Digital databases — which may have just a small number of bones from a private institution or as many as hundreds in larger collections — advance the relevant fields even more. And with the evolution of new scanning and viewing technologies, researchers are able to look inside bone images and manipulate them in ways that would not be possible with the real thing. Bone-scanning technology may also preserve remains for future generations, allowing researchers to avoid physical wear and tear on the originals. And for researchers in many developing countries, digital scans may be the only opportunity to research skeletal collections, as working on specimens in person is often limited by funding constraints.
But these repositories come with loaded ethical questions that have often kept access to human-skeletal data under lock and key. L’Abbé’s South African project isn’t the first to grapple with these issues, but the creators of other repositories haven’t managed to devise universal solutions.

A team of 245 UCLA undergraduates and 31 high school students has published an encyclopedia of more than 1,000 genes, including 421 genes whose functions were previously unknown. The research was conducted in fruit flies, and the genes the researchers describe in the analysis may be associated with the development of the brain, eye, lymph gland and wings.
The fruit fly is often the object of scientific research because its cells have similar DNA to that of human cells — so knowledge about its genes can help researchers better understand human diseases. The UCLA study should be useful to scientists studying genes involved in sleep, vision, memory and many other processes in humans.

The University’s Carey School of Business recently announced that it is planning on launching a drastic redesign of its Master of Business Administration program.
The changes, which should become part of the curriculum in Fall 2020, will offer two additional pathways toward the degree.
The analytics, leadership and innovation pathway will offer an increased focus on the analytical aspects of business. The health, technology and innovation pathway will focus on health care. The latter pathway seeks to utilize the University’s strength in medicine to help students become leaders in health-care management.
Washington State University faculty who are studying or using artificial intelligence (AI) in their work now have a resource for building collaboration and research efforts.
A new web portal includes information to connect faculty interested in AI across WSU, serving as a resource for researchers as well as for collaborators and supporters.
“AI is a rapidly expanding field of research at WSU—both from the fundamental science and engineering as well as applications perspectives,” said Chris Keane, vice president of research. “We want to provide a point of contact to identify AI research areas that match with WSU faculty and staff research interests and capabilities as well as a place to identify current and emerging research opportunities.”
Northeastern associate professors Christoph Riedl and Brooke Foucault Welles are preparing to embark on a three-year project that could yield such a gadget. The researchers will be studying from a social science perspective how teams communicate with each other as well as with smart devices while solving problems together.
“The vision that we have [for this project] is that you would have a device, maybe something like Amazon Alexa, that sits on the table and observes the human team members while they are working on a problem, and supports them in various ways,” says Riedl, an associate professor who studies crowdsourcing, open innovation, and network science. “One of the ways in which we think we can support that team is by ensuring equal inclusion of all team members.”
The pair have received a $1.5 million, three-year grant from the U.S. Army Research Laboratory to study teams using a combination of social science theories, machine learning, and audio-visual and physiological sensors.
Now in its second year, a UC Berkeley basic life skills class has become so popular that it’s had to turn 200 wannabe adults away. The eight-week pass/no pass course teaches young people how to be more responsible and grown-up, ie. how to “adult.” They learn how to budget for food, do taxes, manage relationships, and more.
Giant-scale physics experiments are increasingly reliant on big data and complex algorithms fed into powerful computers, and managing this multiplying mass of data presents its own unique challenges.
To better prepare for this data deluge posed by next-generation upgrades and new experiments, physicists are turning to the fledgling field of quantum computing to find faster ways to analyze the incoming info.
Cambridge, MA February 12, starting at 5 p.m., Harvard University (Wasserstein Hall). “Zac Kriegman will describe his path from a Harvard JD to a data science career focused on deep learning, and demonstrate a case study illustrating how some of these new techniques were applied to a legal annotation task to produce legal summaries on par with human annotators, allowing Thomson Reuters to improve quality, expand coverage and reduce costs.” [free, registration required]
“The National Science Foundation (NSF)-sponsored Ecological Forecasting Initiative Research Coordination Network (EFI-RCN) project, in partnership with the National Ecological Observatory Network (NEON), invites researchers to apply to an interactive workshop focused on ecological forecasting using NEON data from May 12-14, 2020 at the NEON headquarters in Boulder, CO.” Deadline to apply is February 14.
“The aim of the M5 Competition is similar to the previous four: that is to identify the most appropriate method(s) for different types of situations requiring predictions and making uncertainty estimates. Its ultimate purpose is to advance the theory of forecasting and improve its utilization by business and non-profit organizations. Its other goal is to compare the accuracy/uncertainty of ML and DL methods vis-à-vis those of standard statistical ones, and assess possible improvements versus the extra complexity and higher costs of using the various methods.” Deadline for submissions is June 30.
Stamen worked with the National Audubon Society to visualize the future of bird species across North America in the face of climate change. Eric Rodenbeck, CEO and creative director of Stamen, sat down to talk with the team to talk about this new work, Survival by Degrees: 389 Bird Species on the Brink.
Across the web, there are millions of datasets about nearly any subject that interests you. If you’re looking to buy a puppy, you could find datasets compiling complaints of puppy buyers or studies on puppy cognition. Or if you like skiing, you could find data on revenue of ski resorts or injury rates and participation numbers. Dataset Search has indexed almost 25 million of these datasets, giving you a single place to search for datasets and find links to where the data is. Over the past year, people have tried it out and provided feedback, and now Dataset Search is officially out of beta.
The goal of this article is to document how I have developed this machine learning + causal inference project from end to end. I intend to share my successes and failures from the project and what I learned along the journey. What was really challenging about this project was that I needed to apply a wide range of skills (e.g., parsing HTML pages, sampling, classifying texts, and inferring causality in time series data) at the different stages. But, that’s also what made working on the project so fun!

We present Meena, a multi-turn open-domain chatbot trained end-to-end on data mined and filtered from public domain social media conversations. This 2.6B parameter neural network is trained to minimize perplexity, an automatic metric that we compare against human judgement of multi-turn conversation quality. To capture this judgement, we propose a human evaluation metric called Sensibleness and Specificity Average (SSA), which captures key elements of good conversation. Interestingly, our experiments show strong correlation between perplexity and SSA. The fact that the best perplexity end-to-end trained Meena scores high on SSA (72% on multi-turn evaluation) suggests that a human-level SSA of 86% is potentially within reach if we can better optimize perplexity. Additionally, the full version of Meena (with a filtering mechanism and tuned decoding) scores 79% SSA, 23% higher than the next highest scoring chatbot that we evaluated.
