A Multilevel Wavelet Decomposition Network Hybrid Model Utilizing Cyclic Patterns for Stock Price Prediction

Figure 2

Comparison of series of different lengths after decomposition. (a) is the original data, (b) is the high-frequency subseries of level 3 decomposition, (c) is the high-frequency subseries of level 2 decomposition, and (d) is the high-frequency subseries of level 1 decomposition. The abovementioned decomposition has not been downsampled.
