Using deep learning to expertly detect hemorrhages in brain scans

A computer algorithm co-developed by Vision Group alumnus Weicheng Kuo (Ph.D. '19), post doc Christian Hӓne, their advisor Prof. Jitendra Malik, and researchers at UCSF, bested two out of four expert radiologists at finding tiny brain hemorrhages in head scans, an advance that one day may help doctors treat patients with traumatic brain injuries, strokes and aneurysms.  The algorithm found some small abnormalities that the experts missed, noted their location within the brain, and classified them according to subtype.  The researchers used of a type of deep learning known as a fully convolutional neural network (FCN) to train the algorithm on a relatively small number of images that were packed with data.  Each small abnormality was manually delineated at the pixel level. The richness of this data — along with other steps that prevented the model from misinterpreting random variations, or “noise,” as meaningful — created an extremely accurate algorithm.

Corelight raises $50m for network traffic analysis in the cloud

Corelight, a start-up founded by CS Prof. Vern Paxson, has secured an additional $50 million in Series C financing for its network traffic analysis (NTA) solutions for cybersecurity.  The company has raised a total of $84 million to date, with investment from General Catalyst, Accel, Osage University Partners and Riverbed Technology Co-founder (and former Berkeley CS professor) Steve McCanne. It has more than doubled in size since its Series B in September 2018.  Corelight  is built on an open source framework called Zeek (formerly Bro), which Paxson began developing in 1995.  Zeek is now widely regarded as the gold standard for both network security management (NSM) and NTA, and has been deployed by thousands of organizations around the world.

Alexandra von Meier explains why locally sourced power may be the solution to California's vulnerable energy grid

EE Adjunct Prof. Alexandra von Meier, who is the director of the CITRIS California Institute for Energy and Environment (CIEE)’s Electric Grid program, is the subject of a Berkeley News interview titled "Our energy grid is vulnerable. Locally sourced power may be the answer."   In light of last week's massive PG&E power outage, Von Meier discusses why the current power grid is a fire hazard, why solar power is not a practical alternative during a power outage, and ways to make the grid safer.  She also explains how one of CIEE's research projects, EcoBlock, which is looking into stand-alone microgrids of electrical generation and storage that could be shared among multiple households on a city block, might offer a possible solution.

Ren Ng weighs in on why your photos are about to get a lot better

CS Prof. Ren Ng is quoted in a New York Times article titled "The Reason Your Photos Are About to Get a Lot Better."  The article describes how computational photography is driving the future of phone cameras.  “Most photos you take these days are not a photo where you click the photo and get one shot,” said Ng. “These days it takes a burst of images and computes all of that data into a final photograph.”  He and his students are researching new techniques in computational photography, like applying portrait-mode effects to videos.  One type of effect could be to set the recorded footage to automatically focus on whomever is speaking.  “These are examples of capabilities that are completely new and emerging in research that could completely change what we think of that’s possible,” said Ng.

How to Stop Superhuman A.I. Before It Stops Us

EECS Prof. Stuart Russell has penned a New York Times Op-Ed titled "How to Stop Superhuman A.I. Before It Stops Us," in which he explains why we need to design artificial intelligence that is beneficial, not just smart.  "Instead of building machines that exist to achieve their objectives," he writes, we need to build "machines that have our objectives as their only guiding principle..."   This will make them "necessarily uncertain about what these objectives are, because they are in us — all eight billion of us, in all our glorious variety, and in generations yet unborn — not in the machines."  Russell has just published a book titled "Human Compatible: Artificial Intelligence and the Problem of Control" (Viking , October 8, 2019).

Berkeley EECS well represented at Tapia 2019

An outstanding group of students, faculty, staff, and alumni, represented Berkeley EECS at the 2019 ACM Richard Tapia Celebration of Diversity in Computing, which took place in San Diego in September.  Attendees included:  Profs. Dan Garcia and Armando Fox;  staff Audrey Sillers, Antoine Davis, and Sheila Humphreys; alumni Valerie Taylor (Ph.D. '91, advisor David Messerschmitt), Jeff Forbes (Ph.D. '02, advisor: Stuart Russell), Hakim Weatherspoon (Ph.D. '06, advisor: John Kubiatowicz), Colleen Lewis (EECS B.S. '05/CS M.S. '09), Jorge Ortiz (Ph.D. '13, advisor: David Culler), and Beth Trushkowsky (Ph.D. '14, advisor: Armando Fox); and a cadre of current graduate and undergraduate students.  Former EECS Prof. Jennifer Mankoff, who is now at the University of Washington, was a keynote speaker.

A Latinx Heritage Month profile of Dan Garcia

CS alumnus and Teaching Prof. Dan  Garcia (M.S. ' 95, Ph.D. '00, advisor: Brian Barsky) is the subject of a profile celebrating Latinx Heritage Month in the EECS department.  As a Nuyorican whose father was from Puerto Rico, Garcia "always coveted" his Hispanic heritage and actively explored as much of the Latinx culture as he could.  Known to "bring the flavor" to his students before finals, Garcia is particularly passionate about broadening the participation of underrepresented students in computing.

Celebrating Latinx Heritage Month with Armando Fox

CS Prof. and alumnus Armando Fox (Ph.D. '98, advisor: Eric Brewer) is the subject of a profile celebrating Latinx Heritage Month in the EECS community.  Fox is the child of Cuban refugees who taught him to "pave the road" for those who follow.  He was born in New York City and raised in a bilingual and bicultural household where he was cared for by grandparents who did not speak English.  Fox  is known for his engagement with both campus student groups and national professional organizations to promote and support Latinxs in computing.

Anca Dragan to deliver keynote speech at Ada Lovelace Day celebration

EECS Assistant Prof. Anca Dragan will be the keynote speaker at the 2019 Ada Lovelace Day Celebration of Women in Robotics on Tuesday, October 8, in Sutardja Dai Hall.   The celebration is sponsored by the Women in Tech Initiative (WITI), a joint program of Berkeley Engineering, CITRIS & the Banatao Institute, and CITRIS People & Robotics (CPAR).  It plans to offer "a deep dive into robotic applications for good " and will show participants how "to enter the robotics field with networking, mentoring opportunities, and demos from impressive student groups and supportive community organizations including Women in Robotics/SVR."   Panels will feature leaders from robotics startups, like Tessa Lau (Dusty Robotics), Nicole Kernbaum (Seismic), Jasmine Lawrence (EDEN BodyWorks) and Mai Nguyen (Optoceutics).  Robohub’s selection of the Top 25 Women in Robotics will also be revealed

A snapshot of Edward Ashford Lee in celebration of Latinx Heritage Month

EECS Prof. Emeritus and alumnus Edward Lee (Ph.D. '86, advisor: David Messerschmitt) is the subject of a profile created as part of the EECS Latinx Heritage Month celebration.  Lee discusses some of his Puerto Rican ancestors, including poet/playwright Alejandro Tapia y Rivera, considered one of the fathers of Puerto Rican literature, and physician Bailey K. Ashford, a pioneer in the study of tropical diseases.  Lee shares some of his personal experiences as a member of the Latinx community and even quotes one of his grandfather's Spanglish limericks.
