New open-source platform helps speed up the development of interactive 3D scenes

A team led by CS Assistant Professor Anjoo Kanazawa has created Nerfstudio, an open-source platform to help speed up the development of Neural Radiance Fields (NeRFs). NeRFs are a type of 3D imaging technology that can be used to create photorealistic 3D models of objects and scenes from a series of images. The plug-and-play framework, called Nerfstudio, makes it easier for researchers to create and train NeRFs, allowing users to run NeRFs on real-world data. “Advancements in NeRF have contributed to its growing popularity and use in applications such as computer vision, robotics, visual effects and gaming. But support for development has been lagging,” said Kanazawa. “The Nerfstudio framework is intended to simplify the development of custom NeRF methods, the processing of real-world data and interacting with reconstructions.”

U.S. Senate Hearing: Stuart Russell testifies on AI regulation

CS Professor Stuart Russell testified before the U.S. Senate Committee on Commerce, Science, and Transportation about the regulation of artificial intelligence (AI). In the July 25 hearing, Russell argued that AI is a powerful technology that has the potential to do great good or great harm, and he urged the Senate to take a proactive approach to regulating AI. Russell's testimony focused on three key areas of AI regulation: transparency, accountability, and safety. “My research over the last decade has focused on the problem of control: how do we maintain power, forever, over entities that will eventually become more powerful than us? How do we ensure that AI systems are safe and beneficial for humans? These are not purely technological questions. In both the short term and the long term, regulation has a huge role to play in answering them,” said Russell.

EECS researchers explore unprecedented privacy risks of VR

An article produced by the College of Computing, Data Science, and Society highlighted the increasingly frought landscape of user privacy in the emerging world of Virtual Reality (VR) devices. The article cites two papers published by faculty, students, and visitors affiliated with the Berkeley Center for Responsible, Decentralized Intelligence. Led by CS Ph.D student Vivek Nair and Professor Dawn Song, the research showed that users of such devices can be identified using just minutes of their head and hand movements. Movement data, which is collected and shared with companies and other players to fuel these worlds, can be used to infer dozens of details from age to disability status. One paper demonstrates that body movements are as singular and reliable an identifier as fingerprints, which was accepted for publication at the USENIX Security Symposium. Another found that use of headset data could accurately identify or infer more than 25 characteristics, including location, age and height, which will be published for the Privacy Enhancing Technologies Symposium. “We've done an extensive job of proving that there is a privacy risk here and that it is a different kind of privacy risk than what we have seen on the web,” Nair said. “These kinds of approaches for how to either transform the data or control who has access to it, that's going to be our main focus moving forward." Berkeley RDI is a multi-disciplinary initiative aimed at advancing the science, technology and education of decentralization and empowering a responsible digital economy. This work is part of the center’s Metaverse security and privacy research effort.

Novel agriculture-tech platform developed by Ana Arias and Kristofer Pister featured in Berkeley Engineer

Professors Ana Arias and Kristofer Pister were featured in the Spring 2023 issue of Berkeley Engineer, showcasing their recent development of a tracking system for agricultural land which uses a novel printed sensor array and a wireless communications platform. The technology, dubbed the SmartStake system, uses stake-mounted sensors to provide an inexpensive alternative to cavity ring-down spectroscopy, a state-of-the-art but far more costly method for measuring gases like nitrous oxide, a greenhouse gas that plays a role in climate change. They hope their system, co-developed with Whendee Silver, Professor of Ecosystem Ecology and Biogeochemistry, may someday transform biofuel agriculture by enabling farmers to fine-tune agricultural practices to lower nitrous oxide emissions, while also optimizing fertilizer and irrigation usage. Berkeley Engineer is published twice yearly by Berkeley Engineering’s Office of Marketing & Communications and distributed to more than 50,000 alumni, faculty, donors and friends, highlighting the excellence of faculty, alumni and students and bringing their work to life through news and research stories.
