Diagnosis Systems

The purpose of this full-day workshop, jointly hosted by AAAI, ACM
SIGKDD, and AUAI, was to address common issues in resource-bounded
decision making, especially uncertain reasoning with deadlines. The 11
technical presentations (6 30-minute, 5 10-minute) covered topics
ranging from anytime, anyspace embedded systems to new approaches to
robust search and constraint satisfaction. The workshop emphasis was on
probabilistic techniques and representation by graphical models, both
for inference in diagnosis and monitoring and reinforcement learning in
control and planning.

Three invited addresses were given: D'AMBROSIO surveyed a methodological
spectrum between reactive and introspective approaches to decision
making. A second invited talk by HORSCH dealt with fine-grained control
of reasoning in CSP, and a third by KOENIG presented new real-time
heuristic search techniques for fast dynamic replanning.

The first track focused upon monitoring and diagnosis of failures in
complex systems such as distributed systems (RISH) and assembly lines
(BAYDAR). COZMAN presented on space-time tradeoffs for Bayesian network
inference techniques in real-time embedded systems. The second track
focused on control in new real-time reinforcement learning architectures
(RAJA), scheduling (GREENWALD), and sensor integration (ZHU). The third
track included one paper on localization in real-time by particle
filtering (KWOK) and one on real-time airport scheduling (GOMEZ DE SILVA
GARZA). The fourth and final track covered a novel formulation of image
analysis planning in time-constrained domains as a reinforcement
learning problem (BULITKO) and a prediction-based method for online
inference in graphical models - CP-nets (DOMSHLAK).

The workshop concluded with a brief discussion on common interests and
themes in real-time decision support and diagnosis systems (RTDSDS), and
remarks by the co-chair (HSU) on representations useful in interactive
RTDSDS.

Of 18 original technical publications submitted for review, 8 were
published as full-length papers and the remainder as abstracts.
