Comparison of the elapsed time and maximum memory usage for empirical datasets. a The elapsed time of preprocessing steps such as binalization and normalization (orange bar) and the elapsed time of each PCA calculation itself (green bar). Only when performing the PCA implementations to the Brain dataset, we used our in-house Julia script to preprocess. This is because this dataset cannot be loaded to the memory space as a data.frame of R language. b The memory usage of all principal component analysis (PCA) implementations calculated for each empirical dataset (blue bar)
