Michael Jordan named Plenary Lecturer at the 2018 International Congress of Mathematicians (ICM)

Prof. Michael Jordan has been named a Plenary Lecturer at the 2018 International Congress of Mathematicians (ICM), which will take place in Rio de Janeiro, Brazil, in August.  ICM is considered the world’s premier forum for presenting and discussing new mathematical discoveries.  Plenary speakers are invited from around the world to present one-hour lectures which are held without other parallel activities--an honor that has been bestowed on only a small handful of computer scientists over the 121 year history of the ICM.

Ashokavardhanan, Jung, and McConnell named KPCB Engineering Fellows

Undergraduate students Ganeshkumar Ashokavardhanan (EECS  + Business M.E.T.),  Naomi Jung (CS BA), and Louie McConnell (EECS + Business M.E.T.) have been selected to participate in the 2018 KPCB Engineering Fellows Program, named one of the top 5 internship programs by Vault.  Over the course of a summer, KPCB Engineering Fellows join portfolio companies, where they develop their technical skills and are each mentored by an executive within the company. It offers students an opportunity to gain significant work experience at Silicon Valley startups, collaborating on unique and challenging technical problems.

EECS mourns the loss of Angela Waxman

Angela Waxman, the CS Graduate Student Services Staff Advisor, passed away unexpectedly on Saturday night from a stroke.  Angela joined the EECS department in July 2017, and made a positive impact on those lucky enough to have worked or interacted with her.  Her kindness, warmth and positive spirit will be greatly missed. Contact Shirley Salanio (shirley@eecs.berkeley.edu) for details about the funeral service.

AI training may leak secrets to canny thieves

A paper released on arXiv last week by a team of researchers including Prof. Dawn Song and Ph.D. student Nicholas Carlini (B.A. CS/Math '13), reveals just how vulnerable deep learning is to information leakage.  The researchers labelled the problem “unintended memorization” and explained it happens if miscreants can access to the model’s code and apply a variety of search algorithms. That's not an unrealistic scenario considering the code for many models are available online, and it means that text messages, location histories, emails or medical data can be leaked.  The team doesn't “really know why neural networks memorize these secrets right now, ” Carlini says.  “At least in part, it is a direct response to the fact that we train neural networks by repeatedly showing them the same training inputs over and over and asking them to remember these facts."   The best way to avoid all problems is to never feed secrets as training data. But if it’s unavoidable then developers will have to apply differentially private learning mechanisms, to bolster security, Carlini concluded.

RISELab's AI research wins $10M NSF award

The RISELab, led by Prof. Ion Stoica, has received an Expeditions in Computing award from the National Science Foundation (NSF), providing $10 million in funding over five years to enable game-changing advances in real-time decision making technologies.  The award is presented to research teams pursuing large-scale, far-reaching and potentially transformative research in computer and information science and engineering.   RISELab’s award will be used to develop technology for an era in which AI systems will make decisions that will play an increasingly central role in people’s lives in areas such as healthcare, transportation and business.

Subjects natural, rational, and transcendental: the photos of Lotfi Zadeh

Prof. Lotfi Zadeh, who passed away in 2017, was an avid photographer who grew up in a multicultural environment, surrounded himself with a cosmopolitan crowd, and always kept his mind open to new ideas.   In the 1960s and 70s, he enjoyed capturing the people around him in a series of black and white portraits.  His burgeoning career gave him access to a number of artists, academics, and dignitaries who, along with his colleagues, friends, and family, proved a great source of inspiration for him.   Some of Zadeh's portraits can be viewed in the EECS Newsletter courtesy of Prof. David Attwood.

Ling-Qi Yan helps to improve computer rendering of animal fur

CS graduate student Ling-Qi Yan (advisors: Ravi Ramamoorthi/Ren Ng) and researchers at U.C. San Diego are the subject of an article in TechXplore titled "Scientists improve computer rendering of animal fur."  He is part of a team that developed a method for dramatically improving the way computers simulate fur, and more specifically, the way light bounces within an animal's pelt.  The researchers are using a neural network to apply the properties of a concept called subsurface scattering to quickly approximate how light bounces around fur fibers.  The neural network only needs to be trained with one scene before it can apply subsurface scattering to all the different scenes with which it is presented. This results in simulations running 10 times faster than current state of the art.  "We are converting the properties of subsurface scattering to fur fibers," said Yan. "There is no explicit physical or mathematical way to make this conversion. So we needed to use a neural network to connect these two different worlds."  The researchers recently presented their findings at the SIGGRAPH Asia conference in Thailand.

Dan Wallach to testify about election security and voting machines in Texas

EECS alumnus Dan Wallach (B.S. '93) will testify before the Texas Senate Select Committee on Election Security at a hearing about recent election irregularities in Texas, a review of voting security protocols and the responsibilities and duties of members of the Electoral College.  Specifically, the hearing will examine the use of electronic voting machines and paper ballots, voting fraud and disenfranchisement occurring inside nursing homes and assisted living facilities, outside interference and manipulation of elections, and the voting requirements of presidential electors.  Wallach is widely regarded as an expert on voting machine security.  He is currently an EECS professor at Rice University and a scholar at Rice's Baker Institute for Public Policy. 

Steve Wozniak emphasizes people over technology

CS alumnus Steve Wozniak (B.A.'86) was the inaugural speaker in the Business Thought Leader series at the University of South Florida College of Business.  He answered pre-submitted questions that asked for his best advice for college students and what he might tell his younger self.  He shared his "smiles minus frowns" happiness equation and said that how one feels is paramount to success.  While passion and vision are key, he stressed the importance of always choosing people over technology and cautioned students that ”the purpose [of your work] should never be, this is how I’m going to make a lot of money.”  Instead, if you think about how you can make the world a better place you will never regret the outcome.  He said that he was so famous when he came back to study at Berkeley, after taking time off to found Apple Computers, that he went by the pseudonym Rocky Raccoon Clark.

UC Berkeley wins 2018 Fiesta Bowl Overwatch Collegiate National Championship

For the second year running, UC Berkeley has won the Fiesta Bowl Overwatch Collegiate National Championship, sweeping UC Irvine 3-0.  CS majors Kevin "SlurpeeThief" Royston and Gandira “Syeikh” Prahandika were on the Berkeley team, which battled in front of a sold-out crowd at the game in Tempe, Arizona, the first partnership between a collegiate bowl game and eSports tournament.  Royston, who was profiled in on Overwatch Wire article before the tournament, is in the top 1% of all players worldwide, has had a peak skill rating of 4626, and was on the winning team last year.  He notes that the balance between esports and school has been a tough road.  “It’s definitely rough, this week is the first time I had a homework assignment slip because of Overwatch. (Laughs) Hear me out! It’s for Machine Learning which is the hardest class at Berkeley. We had to travel (for the Fiesta Bowl) and I worked sixteen hours on an assignment and didn’t even get halfway through it.”  Overwatch is a team-based shooter game that was created by Blizzard Entertainment and released in 2016.  Teams are made up of six players, who select different characters, known in the game as “heroes,” to complete different objectives. The Berkeley team won $42,000 of the $100,000 total in scholarships and other prizes.
