New Challenges in Computer Science Research
viernes, 27 de julio de 2012
Posted by Jeff Walz, Head of University Relations
Yesterday afternoon at the
2012 Computer Science Faculty Summit
, there was a round of lightning talks addressing some of the research problems faced by Google across several domains. The talks pointed out some of the biggest challenges emerging from increasing digital interaction, which is this year’s Faculty Summit theme.
Research Scientist
Vivek Kwatra
kicked things off with a talk about video stabilization on YouTube. The popularity of mobile devices with cameras has led to an explosion in the amount of video people capture, which can often be shaky. Vivek and his team have found algorithmic approaches to make casual videos look more professional by simulating professional camera moves. Their stabilization technology vastly improves the quality of amateur footage.
Next,
Ed Chi
(Research Scientist) talked about social media focusing on the experimental circle model that characterizes Google+. Ed is particularly interested in how social interaction on the web can be designed to mimic live communication. Circles on Google+ allow a user to manage their audience and share content in a targeted fashion, which reflects face-to-face interaction. Ed discussed how, from an HCI perspective, the challenge going forward is the need to consider the trinity of social media: context, audience, content.
John Wilkes
, Principal Software Engineer, talked about cluster management at Google and the challenges of building a new cluster manager-- that is, an operating system for a fleet of machines. Everything at Google is big and a consequence of operating at such tremendous scale is that machines are bound to fail. John’s team is working to make things easier for internal users enabling our ability to respond to more system requests. There are several hard problems in this domain, such as issues with configuration, making it as easy as possible to run a binary, increasing failure tolerance, and helping internal users understand their own needs as well as the behavior and performance of their system in our complicated distributed environment.
Research Scientist and coffee connoisseur
Alon Halevy
took to the podium to confirm that he did indeed author an empirical book on coffee, and also talked with attendees about structured data on the web. Structured data is comprised of hundreds of millions of (relatively small) tables of data, and Alon’s work is focused on enabling data enthusiasts to discover and visualize those data sets. Great possibilities open up when people start combining data sets in meaningful ways, which inspired the creation of
Fusion Tables
. An example is a map made in the aftermath of the 2011 earthquake and tsunami in Japan, that shows natural disaster data alongside the locations of the world’s nuclear plants. Moving forward, Alon’s team will continue to think about interesting things that can be done with data, and the techniques needed to distinguish good data from bad data.
To wrap up the session, Praveen Paritosh did a brief, but deep dive into the
Knowledge Graph
, an intelligent model that understands real-world entities and their relationships to one another-- things, not strings-- which
launched
earlier this year.
The Google Faculty Summit continued today with more talks, and breakout sessions centered on our theme of digital interaction. Check back for additional blog posts in the coming days.
