[0017] In the following, the present invention will be further clarified in conjunction with specific examples. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, those skilled in the art will give various equivalent forms of the present invention. All the modifications fall within the scope defined by the appended claims of this application.
[0018] The specific prediction steps of the present invention are as follows:
[0019] (1) Use the dyadic orthogonal wavelet in the discrete wavelet transform (DWT) to transform the effective berth occupancy time series, and use the Mallat algorithm to perform multi-resolution N-scale wavelet decomposition. After decomposition, a scale is N low frequency coefficient vector c N And N high-frequency coefficient vectors d at different scales 1 , D 2 ,...,D N ;
[0020] (2) Use the reconstruction algorithm to separa...
