Process monitoring using non-linear statistical techniques
TL;DR: In this paper, a non-linear principal component analysis (NPCA) is proposed to reduce the dimensionality of the process by creating a new set of variables, principal components, which attempt to reflect the true underlying system dimension.

Neural networks-based scheme for system failure detection and diagnosis
Yee Ming Chen,M. L. Lee +1 more
TL;DR: The scheme can be broken up into three steps: fault detection, diagnosis, and accommodation, and particularly emphasis is placed on fault detection and diagnosis employing neural networks in this paper.

Paper: A survey of design methods for failure detection in dynamic systems
TL;DR: This paper surveys a number of methods for the detection of abrupt changes in stochastic dynamical systems, focusing on the class of linear systems, but the basic concepts carry over to other classes of systems.
