Short BioI am a Professor in the Computer Science Department at the University of Southern California (USC) and Director of Cognitive Architectures at USC's Institute for Creative Technologies (ICT). I was at USC's Information Sciences Institute (ISI) for twenty years, most recently as its Deputy Director. Prior to coming to USC in 1987, I was an Assistant Professor of Computer Science and Psychology at Stanford University from 1984 to1987, and a Research Computer Scientist at Carnegie Mellon University from 1983 to 1984. I received a B.S. degree in Mathematical Sciences (with distinction) from Stanford University in 1976 and M.S. and Ph.D. degrees in Computer Science from Carnegie Mellon University in 1978 and 1983, respectively.
From 1983 until 1998, I was a co-PI of the Soar Project, a multi-disciplinary, multi-site attempt to develop, understand, and apply a cognitive architecture capable of supporting general intelligence. Research on Soar spanned areas such as machine learning, problem solving and planning, production systems, intelligent agents, virtual humans, multi-agent systems, knowledge-based systems, neural networks, and cognitive modeling. The most significant applications were intelligent automated pilots and commanders for synthetic battlespaces, as deployed in Synthetic Theater of War '97 (STOW-97).
From 1998 until 2007 my focus shifted to exploring new directions in computing and related fields for ISI, such as blending entertainment and computing for military training (where I helped to found ICT); virtual organizations of robots, agents and people; responding to the unexpected; high performance computing, scalable distributed computing, and computational science; biomedical informatics; automated construction (where I was Deputy Director of the Center for Rapid Automated Fabrication Technologies – CRAFT); and technology and the arts.
I was elected a Fellow of the Association for the Advancement of Artificial Intelligence (AAAI) in 1994 for work on Soar and a Fellow of the Cognitive Science Society in 2014. I also won both the Kurzweil Award for Best AGI Idea (2011) and the Kurzweil Award for Best AGI Paper (2012) for work on Sigma. I have served as Chair of the Association for Computing Machinery (ACM) Special Interest Group on Artificial Intelligence (SIGART), Councillor and Conference Chair of the AAAI, and Program Co-Chair of the National Conference on Artificial Intelligence (AAAI-92).
Discussions and Interviews
An August 2012 panel discussion among David Brin (an award-winning science fiction writer), Mat Kaplan (the moderator) and me on AI and the Future at KPCC can be found at video.
Part one of an August 2013 interview of me by Adam Ford (founder and president of H+ Australia) on AI and the Future (and Sigma) can be found at video. Part two can be found at video.
A September 2013 interview of me by Luke Muehlhauser (executive director of the Machine Intelligence Research Institute) on Cognitive Architecture (and related topics) can be found at blog.
Current Research Activities
Developing Sigma (Σ),
an attempt to build a functionally elegant, grand unified cognitive
architecture/system – based
on graphical models and piecewise continuous functions – in
support of virtual humans and intelligent
agents/robots. Work to date has focused on memory and
learning; decision making and problem solving; reflection and Theory of
Mind; perception, localization and mental imagery; language and speech;
and affect and attention. More on this effort can be found here. A 2.5 hour tutorial was given on Sigma at AGI '14. Both the video and the slides
are available on their web site. A more recent 3 hour
tutorial, including a hands-on portion, was given at AAMAS '16.
Information about it, including the slides and hands-on tutorial
instructions, can be found here.
A public release of Sigma is also now available under a BSD 2-clause
open-source license. Information on the release and how to set it
up can be found here.
Also included in the release materials is an on-line tutorial that
covers some of the basics of using Sigma for building agents.
Reflecting on the nature and structure of computing. The book On
Fourth Great Scientific Domain (MIT Press) proposes that the
computing sciences are on a par with the physical life and social
sciences, while introducing a relational
approach to understanding
computing, its structure, and its connections with these
other domains. The MIT Press catalog page
for the book is here,
and it is available from Amazon (with one truly dreadful customer review) here. Positive professional reviews can be found in Nature, Computing Reviews, and JASIST (logins may be required).
