Sneha Mehta to attend Deep Learning and Reinforcement Learning Summer School in Canada

DAC Ph.D. student Sneha Mehta is an intern this summer at Netflix headquarters in Los Gatos, California.

Sneha Mehta has been selected to attend the Deep Learning and Reinforcement Learning Summer School (DLRLSS), from July 24 to August 2, in Edmonton, Alberta, Canada.

Mehta is a Ph.D. student in computer science at the Discovery Analytics Center, advised by Naren Ramakrishnan. In May, she began a summer internship as a data scientist at Netflix headquarters in Los Gatos, California, where she is researching novel methods to improve machine translation for subtitles.

“I applied to the Summer School because deep learning and reinforcement learning are very relevant to my work at problem solving both at DAC and at Netflix,” said Mehta. “Hearing directly from some of the pioneers in the field will be a great – and invaluable – experience.”

Tanushree Mitra among first to receive research grant providing access to Facebook data

(From left) Tanushree Mitra and Ph.D. students Prerna Juneja, Shruti Phadke, and Md Momen Bhuiyan participated in a training workshop at Facebook earlier this month.

Tanushree Mitra, assistant professor of computer science in the College of Engineering and a faculty member at the Discovery Analytics Center, has received a Social Media and Democracy Research Grant, giving her access to Facebook data to study how misinformation and other problematic content spread on the platform. This is the first time Facebook has given academics access to its data.

Mitra is among 60 international researchers — and one of only two women principal investigators — to receive the grant, funded by a number of leading foundations and administered through a Social Science One and Social Science Research Council collaborative partnership that bridges the gap between academics and the private sector.  Click here to read more about Mitra’s grant.


Google Faculty Research Award supports work in detecting human-object interaction in images and videos

Jia-Bin Huang, assistant professor of ECE and DAC faculty member

Jia-Bin Huang, assistant professor in the Bradley Department of Electrical and Computer Engineering and a faculty member at the Discovery Analytics Center, has received a Google Faculty Research Award to support his work in detecting human-object interaction in images and videos.

The Google award, which is in the Machine Perception category, will allow Huang to tackle the challenges of detecting two aspects of human-object interaction: modeling the relationship between a person and relevant objects/scene for gathering contextual information and mining hard examples automatically from unlabeled but interaction-rich videos.  Click here to read more about Jia-Bin’s Google Award.


Summer months take DAC students to professional internships and jobs across the country

DAC Ph.D. students Ping Wang (left) and Tian Shi are in Richland, Washington, this summer, where they are interns at the Pacific Northwest National Laboratory.

A number of graduate students at the Discovery Analytics Center have opted for internships and jobs at companies and national laboratories across the country this summer as a way of both benefiting their own research and gaining real world experience.

Following is a list of where they are for the next few months:

Amazon Research Award supports developing algorithms that tackle unfairness in recommendation engines

Bert Huang, DAC faculty member and assistant professor of computer science

Why would a recommendation engine not suggest computer science classes to a female college student interested in that field of study?

According to Bert Huang, assistant professor of computer science in the College of Engineering and a faculty member at the Discovery Analytics Center, there are a few reasons. The engine may have trained from data representing the existing gender imbalance in computer science, unfair patterns may have inadvertently emerged from the mathematical nature of its learning algorithm and model, or there may be a less-visible or harder-to-detect process in place.  Click here to read more about Bert’s work.


Software platform engages communities in school rezoning decisions

Left to right: Colin Flynn, Vicki Keegan, and Susan Hembach from Loudoun County Public Schools meet at the Discovery Analytics Center with Ph.D. students Andreea Sistrunk, Subhodip Biswas, and Fanglan Chen to discuss how Redistrict is helping to establish school attendance zones.

School rezoning decisions often cause emotional stress for families and communities for a variety of reasons.

Parents worry about continuity of programs and activities at a new school, the toll it might take on their children’s friendships, and modes of transportation. School officials, administrators, and staff want to ensure that all students have equitable access to educational programs and facilities. Almost everyone is concerned about the impact a particular school attendance zone will have on traffic patterns, especially at opening and closing times.

DAC Student Spotlight: Payel Bandyopadhyay

Payel Bandyopadhyay, DAC Ph.D. student computer science

Payel Bandyopadhyay is trying to understand the role of 3D immersive environment (an artificial, interactive, computer-created scene or “world” within which a user can immerse themselves) for sensemaking in textual data.

According to Bandyopadhyay, prior work at Virginia Tech by her advisor Chris North and others has shown the part that 2D space plays in sensemaking. Her current research investigates 3D immersive environments to determine if they provide any additional benefit or not.

DAC Student Spotlight: Lulwah AlKulaib

Lulwah AlKulaib, DAC Ph.D. student in computer science

While a master’s degree student in computer science at George Washington University, Lulwah AlKulaib would look for published papers in high impact factor journals and highly respected, top rated conferences matching her field of interest, machine learning.

“This is where I first learned about the Discovery Analytics Center, the research being done there, and that it was located in northern Virginia as well as in Blacksburg,” she said.
