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; recognition of emotion in speech; and models to map different writing styles and languages into common representations. Northeastern’s robotics group takes a computational approach to advancing robotics. Research projects range from system-level control of articulated robots with fifty or more joints to mesoscale issues in compliant actuation and reliable sensing.
Members of the group regularly collaborate with researchers in other fields, including biology, psychology, health sciences, art and design, and law. They also work closely with their College of Computer and Information Science colleagues involved with information retrieval, data mining, and human–computer interaction.
- 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
