Model accuracy under different time-scale feature decompositions: (a) Model accuracy with single or no time-scale feature decomposition operation; (b) Model accuracy with gradually increasing larger time scales starting from smaller one; (c) Model accuracy with gradually increasing smaller time scales starting from larger one; (d) Model accuracy when arbitrarily selecting three time scales. The time scales used in this experiment cover 1H, 2H, 4H, 8H, D, and W.
