It is probably a potential issue. We did not notice the order_id field, and we assumed the original order in the dataset is already chronological. Maybe we should rerun the experiments on this dataset.

1.We rerun the experiments on this dataset and obtained the following results:
2.The ASSISTment 2012 dataset was sorted by 'timestamp': (int(start) + int(end)) // 2, this may destroy the seriality of the data. For example, one data : start = 1, end = 7, so timestamp = 4; another data : start =2, end = 4, so timestamp = 3. Wouldn't it make more sense to sort the dataset by start_time or end_time?
