CSAIL Colloquium

Guillermo SapiroTitle: Learning sparse representations to restore, classify, and sense images and videos
Speaker: Guillermo Sapiro, University of Minnesota
Date: Thursday, May 22 2008
Time: 4:00PM to 5:30PM
Location:

Sparse representations have recently drawn much attention from the signal processing and learning communities. The basic underlying model consist of considering that natural images, or signals in general, admit a sparse decomposition in some redundant dictionary. This means that we can find a linear combination of a few atoms from the dictionary that lead to an efficient representation of the original signal. Recent results have shown that learning overcomplete non-parametric dictionaries for image representation, instead of using off-the-shelf ones, significantly improves numerous image and video processing tasks.

Two CSAIL Students Named Google Anita Borg Scholars for 2008

raluca popaCSAIL is happy to announce that two students, Raluca Ada Popa and Ghinwa Choueiter, have been awarded 2008 Google Anita Borg Scholarships for their academic achievements in the fields of computer science and technology. The $10,000 scholarship is awarded annually to 20 female undergraduate and graduate students pursuing degrees in computer science and technology in the United States.The awards provide support and encouragement to recipients to continue their educations. Applicants were selected on the strength of their academic backgrounds and their demonstrated leadership roles. Popa and Ghinwa ChoueiterChoueiter’s enthusiasm for their respective work is evidenced by their tireless work ethic and desire to make a difference in the world. Both women exemplify the same determination and spirit as the woman for whom the award is named. Dr. Anita Borg (1949-2003) devoted her life to changing the way society thinks about technology and eliminating barriers that keep women and minorities out of computer science and technology. She founded the non-profit Institute for Women and Technology, which now bears her name, as well as a pioneering conference and online community for women in technology.
