New global plastic policy tool illustrates data science center’s approach

News
Sam Pottinger spent years turning the latest advances in artificial intelligence and machine learning into models and dashboards that supported decision-making at Silicon Valley technology companies. At UC Berkeley, he's building those kinds of tools to turn quality environmental science into accessible, actionable information. That's the idea behind the new Global Plastic Policy Tool, an open-source, interactive model where users can explore regionalized data about the production, use and fate of plastic and the effectiveness of potential policies world leaders could use to eradicate related pollution. Working with plastic experts at UC Santa Barbara, Pottinger and others from Berkeley's Eric and Wendy Schmidt Center for Data Science and Environment harnessed cutting-edge technology to make the expected impact of international policy on plastic pollution understandable and useful to global officials as they work to eliminate it by 2040.

How to use AI for discovery — without leading science astray

News
Over the past decade, AI has permeated nearly every corner of science: Machine learning models have been used to predict protein structures, estimate the fraction of the Amazon rainforest that has been lost to deforestation and even classify faraway galaxies that might be home to exoplanets. But while AI can be used to speed scientific discovery — helping researchers make predictions about phenomena that may be difficult or costly to study in the real world — it can also lead scientists astray. In the same way that chatbots sometimes “hallucinate,” or make things up, machine learning models can sometimes present misleading or downright false results. In a paper published online today in Science, researchers at the University of California, Berkeley, present a new statistical technique for safely using the predictions obtained from machine learning models to test scientific hypotheses.

Catherine Browning joins CDSS as Assistant Dean of Educational Programs

News
Catherine Cronquist Browning has been named assistant dean of educational programs and new initiatives at UC Berkeley’s College of Computing, Data Science, and Society (CDSS). She started Nov. 1 in the newly created role, drawing on 18 years of relevant experience at Berkeley. “I’ve been a lecturer, a graduate student and a staff member on campus. I’ve been in a central campus unit, a graduate professional school and the humanities division,” said Browning. “I’ve benefited from lots of different roles and positionalities at Berkeley. I think that provides empathy for various perspectives and objectives, and consideration of how to bring different stakeholders together in a way that feels like their needs are being met and served.” Browning will lead college-wide planning and implementation for educational programs at CDSS, articulating a strategic vision for the future of its instruction.

Want to improve AI safety? Teach robots to ask humans what they want

News
Want to make artificial intelligence systems safe? Design robots to continually ask and learn what humans want, a UC Berkeley expert said during a recent lecture. These robots would defer to humans, looking for and acting on people’s feedback, described Anca Dragan. To succeed in developing safe systems, we must better emulate how humans behave, consider how different people’s values intersect in AI and assess the impact these systems will have on those values. “Every problem is an assistance problem,” Dragan, an associate professor in Berkeley’s Department of Electrical Engineering and Computer Sciences (EECS), said in the Oct. 6 lecture. “It all comes down to understanding humans better from a computational perspective.”

Berkeley Space Center at NASA Ames to become innovation hub for new aviation, space technology

News
The University of California, Berkeley, is teaming up with NASA's Ames Research Center and developer SKS Partners to create research space for companies interested in collaborating with UC Berkeley and NASA scientists and engineers to generate futuristic innovations in aviation, space exploration and how we live and work in space. The Berkeley Space Center, announced today (Monday, Oct. 16), aims to accommodate up to 1.4 million square feet of research space on 36 acres of land at NASA Ames' Moffett Field in Mountain View, leased from NASA. The new buildings, some of which could be ready for move-in as early as 2027, will house not only state-of-the-art research and development laboratories for companies and UC Berkeley researchers, but also classrooms for UC Berkeley students. These students will benefit from immersion in the Silicon Valley start-up culture and proximity to the nation's top aeronautical, space and AI scientists and engineers at Ames.

Thao Thompson joins CDSS as Chief Administrative Officer

News
Thao Thompson has recently been appointed chief administrative officer and assistant dean for administration at UC Berkeley’s College of Computing, Data Science, and Society (CDSS). She started in the role on Oct. 9. Thompson will lead CDSS administration by providing guidance and decision-making on behalf of the college in matters related to strategic planning, policy development, resources, and organizational and program development. 

An expert shares how AI could help doctors treat domestic violence victims

News
Artificial intelligence tools present many risks for society. But this technology also presents opportunities, like improving medical treatment for victims of intimate partner violence. Ten million people are physically abused each year by a domestic partner, and 20,000 calls are placed every day to related hotlines, according to the National Coalition Against Domestic Violence. This Domestic Violence Awareness Month, we spoke to a researcher who believes her AI work could eventually help doctors support victims of intimate partner violence. Irene Chen is an assistant professor at UC Berkeley and UC San Francisco (UCSF) in Computational Precision Health and is affiliated with Berkeley's Department of Electrical Engineering and Computer Sciences.

UC Berkeley, government, industry leaders discuss future skills in AI era

News
Leaders from academia, government and industry met last week to discuss how AI will change the in-demand skill sets of tomorrow. Experts at The Future of Skills in the AI Era inaugural symposium on Sept. 22 also spoke about preparing society to fill those needs and developing ethical guidelines for human-compatible technologies. Participants included California Secretary of Government Operations Amy Tong, California Privacy Protection Agency Executive Director Ashkan Soltani, NASA Ames Research Center Acting Deputy Director David Korsmeyer, Nvidia Global AI Senior Scientist Alison Lowndes, and European Union, French and Ukrainian officials. The one-day event at National Aeronautics and Space Administration’s Ames Research Center in Moffett Field, Calif., was organized by NASA, Berkeley’s Fisher Center for Business Analytics in the Haas School of Business, and the new College of Computing, Data Science, and Society (CDSS).

This statistics class turns large lectures into chances for connection

News
Welcome to Stat 20, an introductory probability and statistics course and one of the few “flipped” classes at UC Berkeley. Students are introduced to new concepts through their homework and tackle practice problems during “lecture” sections. The format aims to improve comprehension, connection and attendance. A flipped classroom approach isn’t new, with decades’ worth of research proving its effectiveness. But classes like Stat 20 put a Berkeley spin on that model. As many educators work to reimagine the post-pandemic classroom, this structure offers one pathway to tackle large lectures differently and “humanize” these kinds of courses.

Jaron Lanier wants you to stop saying ‘AI’

News
Microsoft’s prime unifying scientist has a message: “Artificial intelligence” does not exist. At a Sept. 13 lecture at UC Berkeley, Jaron Lanier urged the audience to look past what they learned from science fiction as children and stop treating AI systems as entities. Instead, they should talk about the tools as social collaborations trained on materials by people. “It doesn’t matter technically,” Lanier said. But “if you analyze it on those terms, you have a much more actionable way of understanding it, and if you integrate it into society on those terms you have a brighter and more actionable set of paths open for the future of society.”
