Learning Interface Agents
Pattie Maes, M.I.T. Media-Laboratory
Seminar on People, Computers, and Design
Stanford University January 14, 1994
Interface agents are computer programs that employ Artificial Intelligence techniques in order to provide assistance to a user dealing with some computer-based task(s). In this talk I will present several implemented examples of interface agents which have been modelled after the metaphor of a personal apprentice. These agents learn how to assist the user by (i) observing the user's actions and imitating them, (ii) receiving user feedback when they take wrong actions, (iii) being trained by the user on the basis of hypothetical examples and (iV) asking other agents (working for other users) which have more experience for assistance. I will discuss how these learning agents can be implemented using memory-based learning and statistical learning techniques. I will present results from three prototype agents built using these techniques:
* an agent which assists a user with the scheduling of meetings (accept/reject, schedule, reschedule, negotiate meeting times, etc),
* an agent which assists the user with electronic mail (sorting, prioretizing, forwarding, archiving), and,
* an agent which assists the user with filtering of electronic news (in particular Usenet Netnews).
The talk will be concluded with some plans for current and future research.
Pattie Maes received her PhD in Computer Science from the University of Brussels in Belgium in 1987. In 1989 she came to the MIT Artificial Intelligence Laboratory to work with Marvin Minsky and Rodney Brooks on modeling and building Intelligent Autonomous Agents. In 1991 she joined the MIT Media Laboratory as an tenure track Assistant Professor. Once at the Media Laboratory, she started thinking about how her work on Intelligent Agents could be applied to the problem of Human-Computer Interaction. In particular, her own frustration with hours of waisted time reading electronic mail, browsing through electronic bulletin boards and electronic news and scheduling meetings motivated her to build computerized personal assistants that help a user with daily tasks and activities.
Titles and abstracts for all years are available by year and by speaker.
