Chang-Tien Lu leads Virginia Tech in NSF Big Data Innovation Hub

Virginia Tech graduate students use a display wall in the Discovery Analytics Center to view epidemiological simulations of disease outbreaks in a city, one of the many big data applications that will be studied in the Big Data Innovation Hub.

Virginia Tech graduate students use a display wall in the Discovery Analytics Center to view epidemiological simulations of disease outbreaks in a city, one of the many big data applications that will be studied in the Big Data Innovation Hub.

Chang-Tien Lu, associate professor of computer science and associate director of DAC is leading Virginia Tech as it takes part in a multi-university effort to apply big data solutions to regional challenges. Chang-Tien will be playing a vital role in the university’s broad-base collaboration on the project, an initiative supported by the National Science Foundation that brings together research universities across the south to develop a Big Data Regional Innovation Hub.  Read more about Chang-Tien’s part in this project here.

Devi Parikh and Dhruv Batra, DAC faculty members and assistant professors of electrical and computer engineering have received another Google Research Award in the amount of $92,000 for their Visual Question Answering (VQA) project. This is Parikh’s third Google Research grant, and Batra’s second. The grant will be to develop a new approach in teaching computers to understand images with the goal of enabling the computer to provide a natural-language answer to a specific question.  To read more about the grant click here.

 


Aditya Prakash receives one of only ten Facebook Faculty Award

badityap-portraitCongratulations to Aditya Prakash on his Facebook Faculty Award, one of only 10 such awards given this year! The award will support novel information diffusion related research focusing on understanding, predicting and countering virality on social-media websites and platforms. For example, some of the questions Aditya will study include: “What content could go viral? How much and when? Given a context, how to identify and counter negative viral campaigns?” Look forward to exciting results from this research!
