Feature selection is crucial as extracting all possible features and creating a model based on those features results in two major disadvantages, i.e. high computational cost and inefficient complexity of the model, which leads to overfitting. In this paper, four statistical feature selection methods are applied to the TCM problem in a CNC-milling machine. These methods are Ridge Regression (RR), Principal Component Regression (PCR), Least Absolute Shrinkage and Selection Operator (LASSO), and Fisher's Discriminant Ratio (FDR). Applicability of these methods are compared based on their diagnostic results in two cases using a single Hidden Markov Model (HMM) approach. © 2012 IEEE.||Source Title:||Proceedings of the 2012 7th IEEE Conference on Industrial Electronics and Applications, ICIEA 2012||URI:||http://scholarbank.nus.edu.sg/handle/10635/70325||ISBN:||9781457721175||DOI:||10.1109/ICIEA.2012.6360911|
