Approaches for time series similarity analysis based on transformation
Wei Liu, Shao Liang-shan · Journal of Liaoning Technical University · 2007
To solve the problem of time series similarity comparison,the paper uses the method of studying time series with intuitive features and gives the definition of time series similarity based on the transformation from the shape features of time series.Then the paper gives the analysis of what natures a good time series transformation function should have.A number of representative time series similarity analysis methods are discussed based on the transformation.The basic ideas of these methods are analysed and the advantages and disadvantages of these methods summarized.A more comprehensive overview of modem time series analysis method is given based on the transformation.At the same time,the definition using transformation functions is given and research directions and theoretical basis are provided for the time series similarity comparison work.
