Mathematical, Computational and Applied Data Science Lab is a research lab in the Khoury College of Computer Sciences at the Northeastern University, led by Dr. Ehsan Elhamifar. Our research includes 1) development of mathematical and computational techniques to model and analyze complex problems involving massive and heterogenous high-dimensional data, 2) design of robust, efficient and scalable algorithms to perform learning, inference and decision making on big data using developed mathematical models, and 3) application of our methodologies and techniques to solve challenging real-world problems in computer vision, robotics and other areas. Current research in the lab includes Big Data summarization, procedure learning from instructional video data, high-rank matrix completion, large-scale object and activity recognition with small or no labeled data and active learning in visual data.
