A Weighted kNN Fault Detection Based on Multistep Index and Dynamic Neighborhood Scale under Complex Working Conditions

Fault detection based on <italic>k</italic>-nearest neighbor (FD-<italic>k</italic>NN) is one of the most widespread fault detection techniques for industrial processes under complex working conditions, owing to its characteristic of local modeling. However, its state separat...
