Explore UC Berkeley’s culture of entrepreneurship with Hriday Kemburu

CS alumnus Hriday Kemburu (B.A. '16) is featured in a Daily Cal article about UC Berkeley’s start up ecosystem titled "‘Dream, build and start up’: Exploring UC Berkeley’s culture of entrepreneurship.'   Kemburu is the CEO of Wildfire,  which began as a UC Berkeley-specific safety app during Kemburu's senior year and branched out into a communications platform spanning more than 30 campuses.  Wildfire is used for spreading the word about anything from crimes to celebrity sightings.  Berkeley's network of startup incubators, accelerators, investors and classes have helped launch hundreds of companies.

Jun-Yan Zhu wins ACM SIGGRAPH Outstanding Doctoral Dissertation Award

CS alumnus Jun-Yan Zhu (Ph.D. '17, advisor: Alexei Efros) has won the Association for Computing Machinery (ACM) Special Interest Group on Computer Graphics and Interactive Techniques (SIGGRAPH) Outstanding Doctoral Dissertation Award. Zhu is a pioneer in the use of modern machine learning in computer graphics. His dissertation is arguably the first to systematically attack the problem of natural image synthesis using deep neural networks. As such, his work has already had an enormous impact on the field, with several of his contributions, most notably CycleGAN, becoming widely-used tools not just for researchers in computer graphics and beyond, but also for visual artists.

Panamanian Hackers Unite!

The inaugural edition of PanamaHackea, an educational hackathon for the peoples of Panama, will be held on Saturday, September 29, 2018, in Torre de Las Américas, Panama City.  This event is the brainchild of 6 students from 4 schools, including Berkeley CS junior Rafael Félix, who hope to inspire and empower "a new generation of Panamanian designers, entrepreneurs, and engineers" by making new technologies more available and accessible to everyone.  In the months leading up to the event, they will create and share tutorials, workshops, tools and resources covering topics from the basics of programming to the latest in Machine Learning.  Participants will enjoy space, food, comaraderie, challenges, and prizes, in a supportive and collaborative environment.

Maxim Rabinovich named 2018 Hertz-Gates Fellow

CS Ph.D. student Maxim Rabinovich (joint advisors: Michael Jordan and Daniel Klein) has received a 2018 Fannie and John Hertz Foundation Hertz-Gates Fellowship in Global Health and Development.  Rabinovich is currently researching machine learning and natural language processing, and is interested in developing artificial intelligence tools that support and extend human reasoning. Recent work in this direction includes projects on minimax theory for multiple testing, code generation from natural language specifications, fine-grained entity typing, and function-specific mixing rates for MCMC.  Rabinovich's work has been supported by the Hertz Foundation since 2015.

Chelsea Finn is one of MIT TR's 2018 35 Innovators Under 35

CS PhD student Chelsea Finn (advisers: Pieter Abbeel and Sergey Levine) has been named to MIT Technology Review's 2018 list of "35 Innovators Under 35," an honor which recognizes "exceptionally talented young innovators whose work we believe has the greatest potential to transform the world."  Finn is cited in the Pioneers category because "her robots act like toddlers—watching adults, copying them in order to learn."  She works in the Berkeley AI Research Lab (BAIR) developing robots that can learn just by observing and exploring their environment. Her algorithms require much less data than is usually needed to train an AI—so little that robots running her software can learn how to manipulate an object just by watching one video of a human doing it. “In many ways, the capabilities of robotic systems are still in their infancy,” she says. “The goal is to have them gain common sense.”

Tiffany Perumpail wins Teaching Effectiveness Award

EECS undergraduate Tiffany Perumpail has won a Teaching Effectiveness Award (TEA) from the UC Berkeley Graduate Division.  This very competitive award is bestowed annually by the Graduate Council’s Faculty Advisory Committee for GSI Affairs.  Applicants submit essays in which they identify a problem they encountered in teaching, explain their strategy and rationale in devising a solution, and assess the effectiveness of the solution. Perumpail's essay, about her experience TAing CS61A, is titled "Improvement of Academic Intern Experience and Performance in Introductory Computer Science."  

PerfFuzz wins ISSTA18 Distinguished Paper Award

"PerfFuzz: Automatically Generating Pathological Inputs," written by graduate students Caroline Lemieux and Rohan Padhye, and Profs. Koushik Sen and Dawn Song, will receive a Distinguished Paper Award from the ACM SIGSOFT International Symposium on Software Testing and Analysis (ISSTA) 2018 in Amsterdam in July.  PerfFuzz is a method to automatically generate inputs for software programs via feedback-directed mutational fuzzing.  These inputs exercise pathological behavior across program locations, without any domain knowledge.   The authors found that PerfFuzz outperforms prior work by generating inputs that exercise the most-hit program branch 5x to 69x times more, and result in 1.9x to 24.7x longer total execution paths.

Microsoft acquires Semantic Machines

Semantic Machines, an artificial intelligence startup co-founded by Prof. Dan Klein and staffed by a number of EECS alumni, has been acquired by Microsoft to help Cortana hold more natural dialog with users.  The team has built a number of machine learning components which work together for a smarter AI, and move beyond the more basic back-and-forth currently supported by the Google Assistant, Apple’s Siri, and Amazon’s Alexa.

In addition to Klein, the team includes Percy Liang (Ph.D. '11), David Hall (Ph.D. '12), Adam Pauls (Ph.D. '12), David Burkett (Ph.D. '12), Jason Wolfe (Ph.D. '11 adviser: Stuart Russell), Yuchen Zhang (Ph.D. '16), Taylor Berg-Kirkpatrick (B.A. '08/Ph.D. '15), Greg Durrett (Ph.D. '16), Alex Nisnevich (M.S. '14), current grad student Jacob Andreas, Charles Chen (B.A. CS/Math '11), Andrew Nguyen (B.A. CS/Linguistics '12), Chuck Wooters (Ph.D. Speech Recognition '93), and consultant Prof. Michael Jordan.

Luke Strgar thinks that Blockchain can be used to track gun sales in America

Graduating CS senior Luke Strgar thinks he might have a solution for the fraught issue of guns in America: Use blockchain to track gun sales.  Strgar thinks that Blockchain offers the perfect balance between security, anonymity and scale that could please people on all sides of the gun-control debate.  He spent two days in Washington, D.C. this month pitching the idea of a centralized, ultra-secure, online gun-sale database to legislative aides and think-tank analysts.  A database like this could be monitored by everyone and could not be abused by the government.  “The goal here is to find a solution that both parties can agree on,” Strgar said. “I am not interested in developing something for one side of the discussion, that people try to force down the throat of parties coming from the other side. One of the nice things about technology is that you can develop systems that work for people.”

Nick Carlini embeds hidden commands to Alexa and Siri in recordings of music and spoken text

CS graduate student Nicholas Carlini  is featured in a New York Times article titled "Alexa and Siri Can Hear This Hidden Command. You Can’t." He and his advisor, David Wagner, have published a paper showing they can embed audio instructions, undectable by human beings, directly into recordings of music or spoken text. They can secretly activate the artificial intelligence systems on smartphones and smart speakers, making them dial phone numbers or open websites. In the wrong hands, the technology could be used to unlock doors, wire money or buy stuff online — simply with music playing over the radio.  “We want to demonstrate that it’s possible,” he said, “and then hope that other people will say, ‘O.K. this is possible, now let’s try and fix it.’ ”  Carlini was among a group of researchers who showed in 2016 that they could hide commands in white noise played over loudspeakers and through YouTube videos to get smart devices to turn on airplane mode or open a website.
