The input time series and periodicity identification result in each round. a The original synthetic series x0 mixed with periodic and stochastic components; b the input series x0 and the periodic compnent p1 identified in the first round; c the input series x1 and the periodic compnent p2 identified in the second round; d the input series x2 and the periodic compnent p3 identified in the third round
