Photo Editing Algorithm Changes Weather, Seasons Automatically

Photo Editing Algorithm Changes Weather, Seasons Automatically

by Kevin Stacey (Science News Officer, Physical Sciences)

We may not be able control the weather outside, but thanks to a new algorithm being developed by Brown University computer scientists, we can control it in photographs.

The new program enables users to change a suite of “transient attributes” of outdoor photos — the weather, time of day, season, and other features — with simple, natural language commands. To make a sunny photo rainy, for example, just input a photo and type, “more rain.” A picture taken in July can be made to look a bit more January simply by typing “more winter ...

Paul Valiant Becomes Sheridan Junior Faculty Teaching Fellow

Paul Valiant Becomes Sheridan Junior Faculty Teaching Fellow

An expanded version of this story will appear as part of an article on excellence in teaching in the next issue of Conduit, our research and alumni news magazine.

Assistant Professor Paul Valiant of Brown University’s Department of Computer Science (Brown CS) has just received a Sheridan Junior Faculty Teaching Fellowship that will enable his participation in the Harriet W. Sheridan Center for Teaching and Learning’s Certificate 1 program. Throughout this seminar, faculty will refine their teaching and assessment strategies, give and receive peer feedback, and explore their own practices and beliefs about teaching. The end goal is ...

Layla Oesper Wins ISMB Workshop Best Presentation Award

Layla Oesper Wins ISMB Workshop Best Presentation Award

Last week in Boston, Brown University’s Department of Computer Science (Brown CS) and Center for Computational Molecular Biology (CCMB) managed to put a capstone on their achievement of giving a record number of talks at one of the most prominent conferences in Computational Biology.

At the twenty-second annual International Conference on Intelligent Systems for Molecular Biology (ISMB 2014), PhD candidate Layla Oesper’s talk (“Quantifying Tumor Heterogeneity in Whole-Genome and Whole-Exome Sequencing Data”) received the Best Presentation Award, accompanied by a cash prize of $250, for the “HitSeq 2014: High-Throughput Sequencing Algorithms and Applications” workshop.

Reached for comment, Layla ...

Jenkins, Van Dam Featured In "Creative Mind" Conversations

Jenkins, Van Dam Featured In "Creative Mind" Conversations

“Our job is essentially to build things, to build knowledge, to create ideas, even crazy ideas,” says Brown CS Professor Chad Jenkins, “and put them out there so that others can build.” 

As a contribution to Brown University’s 250th Anniversary celebrations, Professor Richard Fishman has interviewed a dozen faculty members as part of the Creative Mind Initiative (CMI), a program to develop innovative strategies for creative thinking.  CMI explores the creative process and integrates it across disciplines as well as between students and faculty.

Professor Andy van Dam and Jenkins were chosen from Brown CS to reflect on ...

Andy Pavlo Wins ACM SIGMOD’s Jim Gray Doctoral Dissertation Award

Andy Pavlo Wins ACM SIGMOD’s Jim Gray Doctoral Dissertation Award

Brown University Computer Science (BrownCS) alumnus Andy Pavlo PhD ’14 has just won the Association for Computing Machinery Special Interest Group on Management Of Data (ACM SIGMOD)’s Jim Gray Doctoral Dissertation Award for his recent thesis (“On the Optimization of Partitioned Database Management Systems”). He’s the first BrownCS recipient of the honor, which recognizes excellent research by doctoral candidates in the database field.

Andy summarizes his research by explaining that most databases in current use are predicated on designs from the 1970s where memory was more expensive and transaction speed reflected the slowness of manual data entry. “Today ...

Alex Tarvo Wins ACM Student Research Competition Award

Alex Tarvo Wins ACM Student Research Competition Award

Brown University Department of Computer Science (BrownCS) alumnus Alex Tarvo PhD ’14 has just won the Association for Computing Machinery (ACM)’s Student Research Competition Award for his research into predicting the performance of multi-threaded programs. He’s the second Brown CS recipient of the honor (Dan Keefe won in 2005 at ACM’s SIGGRAPH conference), which was awarded at the International Conference on Software Engineering (ICSE).

“As we build computers with more and more cores,” Alex explains, “their behavior becomes increasingly complex and difficult to understand.” This challenge was the genesis of his award-winning work: Tarvo has designed models ...

Genevieve Patterson Helps Organize LDV Vision Summit, Sees Opportunity For Undergrads

Genevieve Patterson Helps Organize LDV Vision Summit, Sees Opportunity For Undergrads

Brown University Department of Computer Science (Brown CS) PhD student Genevieve Patterson has just helped organize the LDV Vision Summit, a start-up conference held in New York City to address trends and technologies in digital imaging and video technology. Founded by Evan Nisselson of LDV Capital, an investment group interested in technology-focused projects across the imaging/video spectrum, the summit brought together top technologists and investors with the purpose of shaping the future of imaging and video.

Genevieve’s previous work with professor Serge Belongie of Cornell Tech, one of Nisselson’s collaborators, made her a natural choice to help ...

CS Student Work/Sleep Habits Revealed As Possibly Dangerously Normal

Imagine a first-year computer science concentrator (let’s call him Luis) e-mailing friends and family back home after a few weeks with Brown Computer Science (BrownCS). Everything he expected to be challenging is even tougher than anticipated: generative recursion, writing specifications instead of implementations, learning how to test his code instead of just writing it. Worst of all is the workload. On any given night, he’s averaging –this seems too cruel to be possible– no more than eight or nine hours of sleep.

Wait, what?  Everyone knows that CS students don't get any sleep, so eight or nine ...
