Abstract
Diagnostic systems utilizing a bayesian network model having link weights updated experientially include an algorithm for easily quantifying the strength of links in a Bayesian network, a method for reducing the amount of data needed to automatically update the probability matrices of the network on the basis of experiential knowledge, and methods and algorithms for automatically collecting knowledge from experience and automatically updating the Bayesian network with the collected knowledge. A practical exemplary embodiment provides a trouble ticket fault management system for a communications network. The exemplary embodiment is particularly appropriate for utilizing the automatic learning capabilities of the invention. In the exemplary embodiment, a communications network is represented as a Bayesian network where devices and communication links are represented as nodes in the Bayesian network. Faults in the communications network are identified and recorded in the form of a trouble ticket and one or more probable causes of the fault are given based on the Bayesian network calculations. When a fault is corrected, the trouble ticket is updated with the knowledge learned from correcting the fault. The updated trouble ticket information is used to automatically update the appropriate probability matrices in the Bayesian network.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
