PhD Thesis topic

An Novel formalims for uncertainty management and temporal reasoning called as Temporal Bayesian Network of Events (TBNE) this approach is used for diagnosis and prediction of events of dynamic domains.

A Temporal Bayesian Network of Events (TNBE) is an extension of Bayesian Networks for dealing with temporal information. Each event or state change of a variable is associated with a time interval. The definition of time intervals and their duration for each node is free (multiple granularity). Temporal reasoning is based on probability propagation and gives the time occurrrence of events or state changes with some probability value. The main difference with previous probabilistic temporal models is that the representation is based on state changes instead of state values at different times. This makes the model much simpler in many applications in which there are few changes for each variable in the temporal range of interest. Temporal information in a TBNE is relative, that is, there is not absulute reference. The TBNE has a mechanism for transforming the relatives times to absolutes, based on the timing of the observations.
