Stuart Russell is featured speaker at IP EXPO Europe

CS Prof. Stuart Russell will be speaking on the use of AI, its long-term future and its relation to humanity, at the 2017 IP EXPO Europe showcase.  IP EXPO Europe is an information technology trade show held annually in England which "brings together some of the biggest names, in their respective fields, to tackle the technological issues facing organisations right now."  Other speakers include Brad Anderson of Microsoft and chess champion Garry Kasparov.

Alexi Efros's team offers custom colorization using deep neural networks

CS Prof. Alexei Efros (also alumnus, Ph.D. '03) and his team have developed a new technique, leveraging deep neural networks and AI, to allow novices--even those with limited artistic ability--to quickly add realistic color to black and white images.  "The goal of our previous project was to just get a single, plausible colorization," says Richard Zhang, a coauthor and PhD candidate, advised by Efros. "If the user didn't like the result, or wanted to change something, they were out of luck. We realized that empowering the user and adding them in the loop was actually a necessary component for obtaining desirable results."  They will present their research into "Real-Time User Guided Colorization with Learned Deep Priors" at SIGGRAPH 2017 in August.

EECS faculty envision California's next-gen infrastructure

EE Profs Claire Tomlin,  Costas Spanos and Connie Chang-Hasnain, and CS Prof. David Culler, are featured in a Berkeley Engineer article titled "Smart moves: California's next-gen infrastructure," which describes current UC Berkeley research projects that promise to transform the way we live.  “What’s enabling these infrastructure changes is our ability to compute faster, to share information faster and to provide that information to users very quickly,” says Tomlin.   She envisions “rail-to-drone” expressways, converting railroad rights-of-way to aerial corridors where closely-spaced fleets of drones travel safely.  Spanos predicts self-monitoring buildings so smart they band together and form bargaining alliances, and Chang-Hasnain's team have been working on manufacturing highly efficient but low-cost solar cells by growing nanoscale “forests” of expensive photovoltaics on inexpensive silicon substrates. The Berkeley Institute for Data Science, co-founded by Culler, is “equipping students not just to consume data but to produce insight” which will help guide the changes to come.

Amazing Salto-1P is jumping longer, faster and higher than ever

Bioinspired robot, Salto-1P, is featured in an IEEE Spectrum article titled "Salto-1P Is the Most Amazing Jumping Robot We've Ever Seen."  Born in Prof. Ronald Fearing's Biomimetic Millisystems Lab, Salto-1P is the most recent incarnation of the Saltatorial Locomotion on Terrain Obstacles (Salto) robot which was pronounced the most vertically agile robot ever created last December.  Salto-1P uses a small motor and a system of linkages and gears to jump.  It needs to do most of its control in the air because it spends so little time in contact with the ground, so it uses a rotating inertial tail and two little thrusters to stabilize and reorient itself in between jumps.

See Salto-1P in action as it bounces around and self-destructs.

Somayeh Sojoudi appointed EECS Assistant Professor in Residence

Somayeh Sojoudi has been officially appointed as Assistant Professor in Residence in EECS (50%) and Mechanical Engineering (50%).  Prof. Sojoudi received her PhD in Control and Dynamical Systems at the California Institute of Technology in 2013, and she was most recently an Assistant Project Scientist in Berkeley’s Department of IEOR. She was an assistant research scientist at New York University for two years, and a postdoctoral scholar in EECS at Berkeley for one year. Her research is in the area of analysis, optimization, and control for large complex systems, with applications in health care, Internet  congestion control, and power systems.

Justine Sherry wins the 2016 ACM SIGCOMM Doctoral Dissertation Award

CS alumna Justine Sherry (M.S. '12/Ph.D. '16 advisor: Sylvia Ratnasamy) has won the ACM SIGCOMM Doctoral Dissertation Award for Outstanding PhD Thesis in Computer Networking and Data Communication.  Justine's thesis was on "Middleboxes as a Cloud Service," and brought the benefits of cloud computing to the networking domain.  Justine is now assistant professor at the Carnegie Mellon School of Computer Science.

"Earable" 3D-printed ear-mounted sensors will monitor body's core temperature

EE Prof. Ali Javey and his research into "Earables," are profiled in a Digital Trends article titled 3D printed ear-mounted wearable will Monitor your body's core temperature.  Earables represent a class of ‘structural electronics’ where sensors and electronics are embedded in the fabricated structure itself.  “Monitoring core body temperature in a continuous fashion could have important medical applications,” Javey continued. “Examples can include monitoring patients with severe conditions, or infants.”  Their goals include making the device smaller while expanding the range of sensors implemented.

Rikky Muller takes on the challenge of reverse-engineering the brain

EE Assistant Prof. Rikky Muller will make a presentation on the theme of Reverse-Engineering the Brain at this year's Global Grand Challenges Summit (GGCS).  Muller is co-founder of Cortera Neurotechnologies, a company which designs medical devices for the treatment of incurable neurological conditions. "We can use devices that record brain signals directly from the the motor cortex of the brain and interpret those signals as movements," she says, "and we can use those signals to control robotic arms, for example, or mouse cursors on a screen."  The GGCS,  sponsored by the National Academy of Engineering (NAE), was created to help find solutions for 14 major engineering challenges critical to the future well-being of humanity and the planet.  Muller will also be awarded an NAE Gilbreth Lectureship, established to recognize outstanding young engineers.

Lauren Barghout Joins Last Studio Standing as Chief Vision Scientist

Laura Barghout, a visiting scholar at the Berkeley Initiative for Soft Computing (BISC), has been hired as Chief Vision Scientist of Last Studio Standing, the largest hand-drawn animation studio in the Western Hemisphere.  Barghout invented a Gestalt-based fuzzy inference system and labeling technique that is used commercially in image/video background removal, object recognition and image labeling systems. Her research has contributed to the understanding of context-dependent spatial vision, spatial masking, theoretical and computational psychophysics, and the application of fuzzy set theory to human and machine vision.  "Most animation relies solely on a direction and what's being created," she said . "This invention allows for a softer, more human-like understanding. It captures the flavor and nuance of a subject naturally -- and, again, it's softer. As such, it requires less manual clean up."

Aviad Rubinstein helps show that game players won’t necessarily find a Nash equilibrium

CS graduate student Aviad Rubinstein (advisor: Christos Papadimitriou)  is featured in a Quanta Magazine article titled "In Game Theory, No Clear Path to Equilibrium," which describes the results of his paper on game theory proving that no method of adapting strategies in response to previous games will converge efficiently to even an approximate Nash equilibrium for every possible game. The paper, titled Communication complexity of approximate Nash equilibria, was co-authored by Yakov Babichenko and published last September.  Economists often use Nash equilibrium analyses to justify proposed economic reforms, but the new results suggest that economists can’t assume that game players will get to a Nash equilibrium, unless they can justify what is special about the particular game in question.
