Research on Grey Incidence Measurement Method Based on Dynamic Time Warping Distance
Grey incidence measurement method is core content of grey analysis.As the traditional grey incidence measurement methods only handle sequences with same length,the sequences with different length must be padded by deleting data,mean statistic method or GM(1,1)model prediction.It results in the degree of grey is continued to enlarge and loss useful information.On the basis of dynamic time warping distance,a novel grey incidence measurement method is proposed.It measures the degree of grey incidence by the shortest path in distance matrix of sequences and does not need to pad any data of sequences.Meanwhile,the corresponding grey incidence measurement method to sequences with different length based on dynamic time warping is constructed.It is effective solutions to solve the problems,such as the incidence measurement between grey sequences with different length,timeline stretching and bending.Simulation results show that the method obtains the correct quantitative analysis conclusion when Deng-Degree and generalized degree are failed.
