This record comprises the 0_simulation and 1_postsim folders. The 0_simulation folder consists of the raw .mat files, each representing a multivariate time series, whereas the 1_postsim folder consists of the following pickle files:

normal.pkl, which contains all nominal sequences

anomalous.pkl, which contains all anomalous sequences

control.pkl, which contains all control-counterparts to anomalous.pkl

training.pkl, which contains all pre-determined folds for training

training_clean.pkl, a version of training.pkl without anomalous sequences

testing.pkl, which contains all pre-determined folds for testing

testing_clean.pkl, a version of testing.pkl without anomalous sequences

Each pickle file is a list of 2D NumPy arrays, each representing a multivariate time series. The name of the corresponding .mat file (and, by extension, the label) is present in the metadata. For NumPy object array, it can be read by calling array.dtype.metadata['file_name'].

We decided to omit the 2_preprocessed folder as the contents are specific to the TensorFlow data pipeline and the same data host limitations would apply.
