BIGDATA: IA: Multiplatform, Multilingual, and Multimodal Tools for Analyzing Public Communication in over 100 Languages
In today’s information age, understanding public communication flows around the world is important to United States policy and diplomacy. The challenge for research is to collect, analyze, and interpret information as it is presented worldwide, creating big data that is flowing at high velocity, in large volumes, with much variety in perspective, language, and platforms. […]

CIF: Small: Learning Mixed Membership Models with a Separable Latent Structure: Theory, Provably Efficient Algorithms, and Applications
In a wide spectrum of problems in science and engineering that includes hyperspectral imaging, gene expression analysis, and metabolic networks, the observed data is high-dimensional and arises from an unknown random mixture of a small set of unknown shared latent (hidden) causes. Being able to successfully and efficiently identify the latent causes from the observed […]
CIF: Small: Sensing-Aware Decision Making for High-Dimensional Signals
There has been an explosion in our ability to sense and record the world around us. This has led to new discoveries and allowed us to consider new paradigms in nearly every walk of life. While the promise of these developments is significant, the explosion of sensing has also created substantial challenges. These challenges include […]
TWC: Medium: Collaborative: Towards Secure, Robust, and Usable Gesture-Based Authentication
This project investigates the feasibility of secure, robust, and usable gesture-based authentication as an alternative to traditional alphanumeric passwords and biometrics. It is motivated by the rapid increase in authentication-related security breaches and by the emergence of new human-computer interfaces. While the breaches have demonstrated the seriousness of the issue, two emerging types of gesture-based […]
