Dave Smith, synthesizer and MIDI developer, dies at 72

Groundbreaking synthesizer designer and EECS alumnus Dave Smith (B.S. 1971),  died on May 31st at the age of 72.  As an undergraduate, Smith wrote a program to compose music as a class project.  "The computers were huge," he said. "You wrote programs on punched cards, and you had to turn them into the computer center and wait a few hours to get it back to see if it compiled or not. It was a slow process." He had to print out his scores on a plotter.  "I remember my senior year, one of my professors predicted that one day that the power of one of these [room-sized] computers would only cost $1000, and of course, everybody’s like, 'No, no way, it couldn’t be.'"  After graduation, Smith took a job developing microprocessors at Lockheed Martin and, in his spare time, built an analog sequencer for a Minimoog synthesizer, allowing it to play more than one note at a time. He founded the company Sequential Circuits in 1974 and introduced the first polyphonic and programmable synthesizer four years later, the Prophet-5.  Because it used microprocessors to control its functions, it could store settings in memory, play harmonies by generating five notes at once, and was portable.  It generated what is called "the signature sound of the 1980s" and shaped the music of bands like of Pink Floyd, Parliament, Genesis, Hall & Oates, Michael Jackson, the Cars, Madonna, the Talking Heads, and the Cure.  Smith co-developed the Universal Synthesizer Interface (USI) in 1981 which, for the first time, allowed musicians to communicate digitally with multiple instruments through a single interface.  He convinced four Japanese companies to cooperate on a shared standard, which became MIDI (Musical Instrument Digital Interface) 1.0 in 1982.  “We made it low-cost so that it was easy for companies to integrate into their products. It was given away license-free because we wanted everyone to use it.”  In 1997, as president of Seer Systems, Smith introduced the first professional software synthesizer, a Windows program called "Reality."  Over the decades, instruments designed by Smith were embraced by groups like Radiohead, Nine Inch Nails, Dr. Dre, and Arcade Fire.  MIDI 1.0 has remained ubiquitous for forty years.

Pravin Varaiya has died

EECS Prof. Emeritus and alumnus Pravin Varaiya (Ph.D. 1966, advisor: Lotfi Zadeh) passed away on June 10th from injuries sustained when a truck hit him as he was walking in his neighborhood on April 1.  He was 81 years old.  A Professor in the Graduate School at the time of his death, he was known for his pioneering work in sensing and controls in intelligent transportation systems, and is credited with spearheading the self-driving car revolution in the 1990s.  Pravin Pratap Varaiya was born in India in 1940 and received his B.S. in Electrical Engineering from the University of Bombay in 1960.  He moved to Berkeley to attend graduate school and married Ruth Kosh, a fellow social activist, in 1963. In addition to teaching EE, he was a Professor of Economics from 1975 to 1992.  As the visionary director of the California Partners for Advanced Transportation Technology (PATH) project at Berkeley from 1994 to 1997, he led the construction of the National Automated Highway System (NAHSC) and the development of the first generation of modern self-driving cars.  These were the first autonomous vehicles tested live on California freeways.  His group also built the PeMS system, which revolutionized sensor networks for transportation, and which remains the largest sensor network for highways in the US.  PeMS enabled the California Department of Transportation and dozens of other agencies to finally see, measure, and assess traffic congestion in real-time.  He won the the IEEE Simon Ramo Medal (2022),  AACC O. Hugo Schuck Award (2020), IEEE ITS Lifetime Achievement Award (2018), IEEE Outstanding Research Award (2009), Bellman Control Heritage Award (2008), IEEE CSS Hendrik W. Bode Lecture Prize (2005), IEEE Control Systems Award (2002), and was a fellow of the IEEE and IFAC, and a member of both the AAAS and the NAE.  Varaiya was known for his calm and gentle demeanor, and his passionate and elegant approach to algorithms, control problems, games and strategies. He will be deeply missed.

BAIR Climate Initiative creates partnerships to fight climate change

Berkeley Artificial Intelligence researchers are joining forces with climate experts, government agencies, and industry, as part of the new Berkeley AI Research (BAIR) Climate Initiative, a multi-disciplinary student-led hub dedicated to fighting climate change.  The effort is being led by co-founding director CS Prof. Trevor Darrel and organized by three of his graduate students, Colorado Reed (co-advised by Kurt Keutzer), who will help lead the initiative, Medhini Narasimhan, and Ritwik Gupta (co-advised by Shankar Sastry).  Their objective is to develop AI techniques that address problems with data processing, particularly involving massive data sets. To maximize the benefit to other researchers studying the same problems around the world, all work done by the initiative will be openly published and available without exclusive or proprietary licensing.  One of their first projects, “The Fate of Snow,” will be a collaboration between BAIR Climate Initiative researchers and other scientists and policy experts on the Berkeley campus, Berkeley Lab (LBNL), Meta AI (which belongs to Meta Platforms, Inc.) and the Center for Western Weather and Water Extremes. The researchers plan to apply AI methods to a multitude of openly available weather and satellite data sources to estimate how much water is in the Sierra Nevada snowpack and forecast what that will mean for streadmflow in the region.

Pratul Srinivasan and Benjamin Mildenhall jointly awarded honorable mention for 2021 ACM Doctoral Dissertation Award

Two of EECS Prof. Ren Ng's former graduate students, Pratul Srinivasan and Benjamin Mildenhall, jointly received an honorable mention for the 2021 Association for Computing Machinery (ACM) Doctoral Dissertation Award.  This award is presented annually to the "author(s) of the best doctoral dissertation(s) in computer science and engineering."  Srinivasan and Mildenhall, who both currently work at Google Research,  were recognized "for their co-invention of the Neural Radiance Field (NeRF) representation, associated algorithms and theory, and their successful application to the view synthesis problem."  Srinivasan’s dissertation, "Scene Representations for View Synthesis with Deep Learning," and Mildenhall’s dissertation, “Neural Scene Representations for View Synthesis,” addressed a long-standing open problem in computer vision and computer graphics called the "view synthesis" problem:  If you provide a computer with just a few of photographs of a scene, how can you get it to predict new images from any intermediate viewpoint?  "NeRF has already inspired a remarkable volume of follow-on research, and the associated publications have received some of the fastest rates of citation in computer graphics literature—hundreds in the first year of post-publication."
