Hi everyone, Actually, I have something come up tomorrow as well. So let's do it on Thursday 12:00 noon instead, unless someone can not make it, in which case we will do it tomorrow itself (please email me directly) Sorour: Probably you don't mean 'need to', rather you 'want to' :-) cheers, - Aditya On 6/24/14, 2:32 PM, Sorour Ekhtiari Amiri wrote: > Hi Shashi, > > Congratulation for your graduation.

Aditya Prakash <badityap(a)cs.vt.edu> To: bburg-fac(a)cs.vt.edu, gradstudents(a)cs.vt.edu CC: Devi Parikh <parikh(a)vt.edu>, Dhruv Batra <dbatra(a)vt.edu> You are cordially invited to attend the M.S. Thesis defense of Shashidhar Sundereisan on Tuesday June 17th (next week) at 1:00pm in Torg. 3160A. Committee: B. Aditya Prakash (VT CS, Chair) Naren Ramakrishnan (VT CS) Dhruv Batra (VT ECE) Title: Making diffusion work for you: Finding culprits, filling missing values, and classification sans text Abstract: Can we find people infected with the flu virus even though they did not visit a doctor? Can the temporal features of a trending hashtag or a keyword indicate which topic it belongs to without any textual information? Given a history of interactions between blogs and news websites, can we predict blogs posts/news websites that are not in the sample but talk about the "the state of the economy'' in 2008? These questions have two things in common: a network (social networks or human contact networks) and a virus (meme, keyword or the flu virus) diffusing over the network. We can think of interactions like memes, hashtags, influenza infections, computer viruses etc., as viruses spreading in a network. This treatment allows for the usage of epidemiologically inspired models to study or model these interactions. Understanding the complex propagation dynamics involved in information diffusion with the help of these models uncovers various non-trivial and interesting results. In this thesis we propose (a) A fast and efficient algorithm NetFill, which can be used to find quantitatively and qualitatively correct infected nodes, not in the sample and finding the culprits and (b) A method, SansText that can be used to find out which topic a keyword/hashtag belongs to just by looking at the popularity graph of the keyword without textual analysis. The results derived in this thesis can be used in various areas like epidemiology, news and protest detection, viral marketing and they can be used by people who work with sampled data in graphs. _______________________________________________ Bburg-fac mailing list Bburg-fac(a)cs.vt.edu
