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.

Alexis Gabadinho’s “Workshop on Sequence Analysis and TraMineR

October 11, 2013 – Two months ago, Mr. Alexis Gabadinho, a scientific collaborator at the Institute for Demographic and Life Course Studies at the University of Geneva. We are excited to provide a recorded video of the workshop here on our website.gabadinho_pic

At the workshop, Mr. Gabadinho introduced TraMineR, a downloadable software package in R. Mr. Gabadinho is one of the creators of this program. He demonstrated the versatility of TraMineR  as a software and introduced the use of sequence analysis as a method of analyzing longitudinal data.

The video to this workshop is split into two parts. You can find part one of Sequence Analysis workshop here:

Part two of Sequence Analysis workshop can be watched here:

Additionally, Mr. Gabadinho has generously shared his handouts with us.
