| Abstract(in English) | Linear regression models have been widely accepted in many scientific and engineering fields for the estimation or interpretation of phenomena. When a linear regression model is built, appropriate input variables have to be selected to achieve high estimation performance. This work proposes new methodologies for selecting input variables for linear regression models using nearest correlation spectral clustering (NCSC), which is a correlation-based clustering method. In the present work, NCSC is used for variable group construction, and a few variable groups are selected by their contribution to estimates; it is referred to as NCSC-based variable selection (NCSC-VS). The usefulness of the proposed NCSC-VS is demonstrated through an industrial application to a chemical process. |
