Is There Missing Data in the "omi-12_train.pkl" File in the ASD Dataset? #19

It appears that there may be missing data in "omi-12_train.pkl" since all other files have an equal size of data. Additionally, is it feasible to align the data from these files, which belong to different entities but have the same quantity, along the time dimension?

The metrics in the same entity are aligned along the time dimension, while different entities are not. Therefore, there is no missing data in the "omi-12_train.pkl" file. You may train an independent model for each entity in the ASD dataset for anomaly detection.
