摘要：NOVELTY - The method involves performing Eastman industrial process. A malfunction is obtained. Normal data is taken as training data. Malfunction data is taken as test data. Normal wavelet conversion process is performed. A main element column vector is established. A data matrix is established. Threshold value is arranged. A small wave conversion and Lasso regression are performed. Lasso linear regression is established. A regression coefficient vector is established. USE - Lasso function based small wave conversion and industrial process malfunction detecting method. ADVANTAGE - The method enables increasing malfunction detecting accuracy. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a Lasso function based small wave conversion and industrial process malfunction detecting method. '(Drawing includes non-English language text)'
