Courses Taught

The following is the snapshot of a graduate level AI course that I taught long back. The URLs, email addresses, phone numbers, etc. are no longer valid. However, the course content, lecture notes, and slides/presentations are still available. The slides on logic and semantics have since been used by many universities around the world.

Past Research Projects

CALO (Congnitive Assistant that Learns and Organizes): This SRI led DARPA program funded the last couple years of my PhD research. My contribution to CALO included the semantics & ontology for understanding projects and charts being drawn on a whiteboard during a meeting, an intelligent agent architecture that glued together various components of multimodal diaolog understanding, and a language for programming autonomous agents that could reason, coordinate, and communicate using a logical semantics of dialog/conversations and teamwork.

CoABS (Control of Agent-based Systems): This DARPA program was the precursor to the DAML (Darpa Agent Markup Language) program that enabled and revolutionalized the field of semantic web (web 3.0). Most of my PhD research on semantics of speech acts and conversations/dialogs was funded by CoABS.

Speech & Gesture recognition on mobile devices: This DARPA funded project studied the effects of exertion and random external noise in a real world setting on speech recognition and hand-drawn gestures on mobile devices such as smartphones. Both speech and gesture recognition fail miserably under these conditions and we discovered how Semantics of Multiple Modalities can be used to significantly improve speech and gesture recognition. I designed and implemented the entire system, developed the mobile and backend software, designed and conducted the human factors study, and analysed the collected data.
