Table 3 Three different kinds of time series used for the comparison of different DTW’s implementation, where all the time series are with a length of 1300. “Random” means time series of random walk. “Simulator” means current signals generated by DeepSimulator. “Amplicon library” means the real data downloaded from [33]. Here, we divide the data into two groups, and the time series within each group will compare with each other. For example, in the first random dataset,\(200\times 1000\)means that the first group has 200 time series, the second group has 1000 time series, and the number of DTW comparison is\(200 \times 1000 = 200000\)
