Professor Hanghang Tong’s “Optimal Dissemination on Graphs: Theory and Algorithms”

November 22, 2013 – Hanghang Tong, an Assistant Professor of Computer Science at the City College of the City University of New York, presented his talk, “OptimHanghang Tong - pical Dissemination on Graphs: Theory and Algorithms.” Professor Tong’s research is focused on large scale data mining for graphs and multimedia and has received multiple rewards including best paper award in CIKM 2012 and has published 70 referred articles and more than 20 patents.

In the seminar, Professor Tong talked about his research on graph mining. The techniques discussed are pertinent to studies of networks, such as how rumors spread or how viral marketing expands. Professor Tong offers some insights on how these graphs can be mapped and the math behind it.

Speaker: Professor Lev Manovich, The Graduate Center, CUNY 3181071223_aa4132bae0

Bio: Lev Manovich is the author of Software Takes Command (Bloomsbury Academic, 2013), Soft Cinema: Navigating the Database (The MIT Press, 2005), and The Language of New Media (The MIT Press, 2001) which is described as “the most suggestive and broad ranging media history since Marshall McLuhan.” Manovich is a Professor at The Graduate Center, CUNY and a Director of the Software Studies Initiative at CUNY and California Institute for Telecommunication and Information (Calit2).


OCTOBER 11, 2013, 9 AM to 5 PM @ The Graduate Center, Room 4102

Workshop on Sequence Analysis and Traminer.

Speaker: Mr. Alexis Gabadinho, Scientific Collaborator at the University of Genevagabadinho_pic

Bio: Alexis Gabadinho holds a postgraduate diploma in demography. He is a scientific collaborator at the Institute for Demographic and Life Course Studies at the University of Geneva where he is finishing a PhD on methods for sequence analysis. He is also a junior researcher at the Life Course and Inequality Research Center at the University of Lausanne.

He is a developer of the TraMineR R package for sequence analysis and has taught sequence analysis in doctoral schools at the University of Bristol, Geneva, Lausanne and Lille and in conferences and postgraduate courses. His research interests are the application of data-mining methods in social sciences and the development of methods for categorical state sequences analysis. He worked in particular on measures of sequence complexity and methods for summarizing sets of sequences. His current research is focused on the development of Markovian model oriented methods for sequence analysis that are made available in the PST R package.


OCTOBER 25, 2013, 12 Noon @ The Graduate Center, Room 6112

Featurizing Text: Converting Text into Predictors for Regression Analysis.

Speaker: Professor Robert Stine, Wharton School of the University of Pennsylvania  stine-pic

Bio: Robert Stine is Professor of Statistics in the Wharton School of the University of Pennsylvania.  His research spans a variety of areas with practical applications, ranging from forecasting and spatial temporal models to fundamentals of multiple testing and methods for text analysis. Recent projects consider methods for selecting factors for predictive models from large databases, with particular relevance to the selection of factors that produce cost-effective decisions.  These methods are crucial in the development of predictive models in data mining.  His research has appeared in numerous academic journals, including the Journal of the American Statistical Association, Journal of the Royal Statistical Society, and the Annals of Statistics.  His teaching has been recognized by awards in both the Wharton MBA and Undergraduate programs, and he is the co-author of a recent textbook Business Statistics: Decision Making and Analysis.
