The EMBERS is featured on the cover of the Big Data Journal (Dec 2014 issue)

Venezuelan Spring EMBERS predictions

As featured in the Big Data Journal: “Forecasting has long been a mystic art with techniques shrouded in mystery. Approaches from big data and machine learning are now revolutionizing the science of predictive analytics. The EMBERS system has been producing early warnings of civil unrest across Latin America for over two years. In February 2014, EMBERS forecast the occurrence and spread of student-led protests in Venezuela days in advance. For more information, please see the article by Doyle and colleagues in this issue of Big Data.” Read more

Press Coverage on Devi Parikh’s work in AI

Devi Parikh

Devi Parikh, assistant professor in the department of electrical and computer engineering and DAC faculty member received close to $1 million “to teach machines to use ‘common sense’ in image analysis.” Parikh, who leads the Computer Vision Lab at Virginia Tech, is the recipient of the Allen Distinguished Investigator Award from the Paul G. Allen Family Foundation. She’s using the money to help computers “read” complex images with the use of cartoon clip art scenes. To read more about Devi’s grant click here.

Devi Parikh

Devi Parikh, an assistant professor in the Bradley Department of Electrical and Computer Engineering and DAC faculty member at Virginia Tech, has received an Allen Distinguished Investigator Award for close to $1 million from the Paul G. Allen Family Foundation to teach machines to use “common sense” in image analysis. Parikh uses cartoon scenes crafted from clip art to help computers “read” complex images. “Humans interpreting visual scenes can take advantage of basic knowledge about how objects typically interact, but computers,” Parikh said, “don’t have the same skill”.

EMBERS Featured in Virginia Tech Magazine


The EMBERS project, sponsored by IARPA was featured in a major spread of the Virginia Tech Magazine.

Through the use of big data, Naren Ramakrishnan and his team from the computer science department’s Discovery Analytics Center (DAC) may make forecasting the future as commonplace as forecasting the weather.

The term “big data” refers to the use of algorithms and other tools to train computers to spot trends in collections of information that are too massive and complex to analyze with traditional methods. The proliferation of data has accelerated with the integration of computers into our daily lives, from social media on our phones to tracking buying habits at the grocery store.
