Resumen o descripción
Diagnosis and prediction m some
domains, like medical and industrial
diagnosis, require a representation that
combines uncertainty management and
temporal reasoning. Based on the fact
that in many cases there are few state
changes in the temporal range of
interest, we propose a novel representation
called Temporal Nodes Bayesian
Network (TNBN). In a TNBN each node
represents an event or state change of a
variable, and an arc corresponds to a
causal-temporal relation. The temporal
intervals can differ in number and size
for each temporal node, so this allows
multiple granularity. Our approach is
contrasted with a dynamic Bayesian
network for a simple medical example.
An empirical evaluation is presented for
a more complex problem, a subsystem of
a fossil power plant, in which this
approach is used for fault diagnosis and
event prediction with good results.
