TLDR
Results indicate that neural networks can generalize around the data on which they were trained, yielding better performance for unforeseen inputs than traditional algorithms in the case of the fault diagnosis problem described.
Abstract
A neural network based fault diagnosis system is being developed for use in aerospace systems in which a family of neural nets replaces an online simulation process A new neural network implementation of one of the model-based algorithms was developed The authors summarize a series of computer experiments designed to benchmark the performance of this neural network based fault diagnosis algorithm in an environment where the good components of the systems are only known up to a tolerance band The results indicate that neural networks can generalize around the data on which they were trained, yielding better performance for unforeseen inputs than traditional algorithms in the case of the fault diagnosis problem described >

Node-fault diagnosis and a design of testability

TL;DR: A concept of k-node-fault testability is introduced and a sufficient and almost necessary condition for testability as well as the test procedure is presented, which depends only on the graph of the circuit, not on the element values.

Analog Fault Diagnosis with Failure Bounds

TL;DR: A simulation-after-test algorithm for the analog fault diagnosis problem is proposed in which a bound on the maximum number of simultaneous failures is used to minimize the number of test points required.

Representing and diagnosing dynamic process data using neural networks

TL;DR: The networks trained using raw time-series data were able to diagnose untrained single-fault patterns sampled earlier in the fault-induced transient, than the ones trained using moving average data, and the moving-average network performed as well as the time- series network.

On the implementation of an analog ATPG: the nonlinear case

TL;DR: An analog Automatic Test Program Generation (ATPG) for linear circuits or systems is being developed that is subdivided into off-line and on-line components while the actual test can be run in either a fully automatic mode or interactively.
