(1) Business interpretation 、 Statistics (3 σ \sigma σ, boxplot )
(2) Consider it as a clustering problem (kNN,kMeans)
(3) See it as a prediction problem
Time series prediction
(4) After temporal decomposition , Statistical residual or fitting residual
(5)Isolation Forest
(6) Sliding window method ( Left and right sliding windows , Expansion sliding window ) And coefficient of variation
(7) Deep learning method
