Artificial Intelligence

Researchers in the artificial intelligence group are focused on developing intelligent computer systems, particularly those related to health informatics, game design, and robotics. The areas they examine include:

  • The perception of natural terrain and 3D foot placement in robotics
  • Natural language processing in law and biology
  • The use of relational agents in health monitoring systems; computational sensing
  • User interfaces for preventive medicine
  • Machine learning in intrusion detection
  • The analysis of MRI scans
  • Computational modeling of cognition, emotion, and social behavior
  • Recognition of emotion in speech
  • Models to map different writing styles and languages into common representations

Northeastern’s robotics group takes a computational approach to advancing robotics. Research projects include system-level control of articulated robots with fifty or more joints, mesoscale issues in compliant actuation and reliable sensing, and the development of robot manipulations using tactile information.

  • Created an animated virtual nurse that educates hospital patients about their health conditions and post-discharge self-care, encourages people to exercise and take their medications as prescribed, and uses natural language processing to simulate face-to-face conversations between patients and health professionals
  • Developed legal ontologies to support legal planning and document drafting systems
  • Created relational agents developed using technology test beds for human–machine dialogs
  • Developed new artificial intelligence models of agent behavior and scalable probabilistic frameworks for behavior modeling to address problems in security policy, international conflict, and international development
  • Created multi-agent systems used for interactive narratives and game environments
  • Developed tools to characterize and extract knowledge from biomedical literature
  • Developed operator interface for NASA’s Mars Exploration Rover Mission
  • Recognized with NASA Software of the Year Award for 2004
  • Awarded grants from DARPA and other federal agencies to develop models to map different writing styles and languages into common representations
  • Serving as associate editor of IEEE Transactions on Neural Networks and Learning Systems (TNNLS), and Neuro computing
  • Created Endless Web, an experimental game that tightly integrates procedural content generation into both game mechanics and aesthetics
  • Developed interactive narrative architecture composed of several believable agents using theatre techniques
  • Developed computational emotional and social models for characters that embed a virtual world
  • Involved in developing a coordinated-control architecture for disaster-response robots and creating a manipulation toolbox to improve the performance of NASA robots as part of the DARPA Robotics Challenge
  • Recognized with the Association for Computing Machinery Autonomous Agents Research Award
