Every year, ICSI hosts postdoctoral fellows from Germany who are funded by the German Academic Exchange Program. In September, we welcomed the first four postdocs to arrive in this year's program: Michael Elberfeld, Christof Lang, Erik Rodner, and Daniel Warneke. They will be working on a variety of topics from theoretical algorithms to computer vision.
Last month, ICSI welcomed back one of its first employees: Chuck Wooters. This is Chuck’s third time at ICSI.
Chuck grew up in the San Gabriel Mountains in southern California and entered UC Berkeley as an undergraduate. He planned to get his bachelor’s degree in philosophy and then go to law school, but after taking a course in philosophical linguistics, he decided to switch majors to linguistics. His plans changed again when he became interested in computer science.
Several new papers were published in August, including one that was presented at the USENIX Security Symposium in Bellevue, Washington. ICSI's Christian Kreibich served on the program committee for this conference.
Social networks make it easy to instantly share information, photos, and videos online. For many people, this is a fun way to stay up-to-date with friends and family, but they may not realize the privacy implications of all this sharing.
ICSI scientist Gerald Friedland studies cybercasing, the use of online information to mount attacks in the real world, and, and recommends users consider the following before posting anything online.
1. Who can see/read this post? Public posts can be seen by anybody in the world, including your boss, governments, and even criminals. So rethink: Is the post appropriate for any audience?
2. Will my post offend people, and am I okay with the potential results of offending people? If the information in this post is shared with people I didn't anticipate sharing it with, will that cause any problems (for me, or for others mentioned/shown in my post)?
Earlier this month, ICSI's Bro team held the first "Bro Exchange:" a meeting aimed at bringing together a large number of Bro users to exchange thoughts and experiences deploying the system. Bro is an open-source network security monitor developed by a team of researchers and engineers at ICSI and NCSA. About 50 Bro users from industry, research labs, and universities attended the event, which was hosted by the National Center for Atmospheric Research in Boulder, Colorado.
Computer vision techniques have trouble recognizing subcategories of objects (for example, a vehicle’s model type or a bird’s species). A new method developed by ICSI researchers improves automatic recognition of subcategories by first warping small areas of photos to account for differences in pose and angle, and then grouping the areas according to their similarities.
Spammers who posted almost half a million Twitter messages in order to silence debate over Russia’s election in December likely purchased fraudulent accounts in bulk and posted the tweets from botnets, groups of malware-infected computers under the command of a single person. According to Networking Group researchers, the campaign took advantage of an underground economy based on spam, a phenomenon that researchers are studying in an attempt to improve methods of eliminating spam.
Charles Fillmore is one of the founding fathers of linguistics as it is practiced today. A professor emeritus of UC Berkeley, Chuck is also the director of ICSI’s FrameNet Project, which is building a lexical database, usable by both machines and humans, that describes the relationships between words in order to extract meaning from texts. The work requires the intellectual flexibility and passion for language that have marked his sixty-year career.
