Data science is concerned with the study of data both analytically and predictively, addressing quantitative and qualitative characteristics, and employing cutting edge scientific methods. In this day and age of pervasive information flow, modern knowledge-based societies need tools and means of analyzing and sifting through data to extract and visualize relevant information in a timely manner. The data could be structured such as those found in databases and knowledge bases; semistructured as in streams of financial data, video data, or climate data, and unstructured data as in streams of text from the web, a collection of articles from a newspaper, or large collections of radio shows. The Data Science group at GWU bring several strands of research in Machine Learning, Databases, Data Mining, Natural Language Processing, and Computer Vision together to create a comprehensive program that addresses the challenge of handling "big data".
Prof. Monteleoni's Machine Learning Group is concerned with developing principled methods (known as algorithms) to automatically detect patterns in data. In this era of "Big Data," the various forms of complexity inherent in real data sources increasingly pose challenges for machine learning algorithm design. The GW Machine Learning Group works on the design, analysis, and application of machine learning algorithms, motivated by problems in real data sources, including learning from data streams, learning from raw (unlabeled) data, learning from private data, and climate informatics: accelerating discovery in climate science with machine learning.
Natural Language Processing:
Statistical Natural Language Processing (NLP) is a rapidly growing exciting field of research in artificial intelligence and computer science. Interdisciplinarity is inherent to NLP drawing on the fields of computer algorithms, software engineering, statistics, machine learning, linguistics, pragmatics, information technology, etc. In NLP, we model language and its use. We build both analytical models and predictive ones. In Professor Diab's NLP lab, we address problems in social media processing building robust enabling technologies such as syntactic and semantic processing tools for written texts in different languages, information extraction tools for large data, multilingual processing, machine translation, and computational sociolinguistic processing. Prof. Diab has a special interest in Arabic NLP where the focus has been on investigating Arabic dialects with very few available automated resources.

Prof. Drumwright’s Planning, Optimization & Simulation for Robotics (POSITRONICS) Lab investigates methods at the intersection of planning, optimization and optimal control, and simulation and dynamics toward efficient autonomous wheeled, manipulator, humanoid, and legged robots. The lab's current research is focused in four areas: 1) autonomous mobile manipulation; 2) robust and fast dynamic simulation; 3) high performance vehicles and legged robots; and 4) theory of robotics.
