Thanks for sharing this wonderful dataset!

The repo and the paper explain that this dataset contains 863 SKUs, while the statistics reveal that the unique count of product_id is 865. I wonder why.

Thank you for pointing this out. This is indeed an oversight on our part. At the time, we first conducted basic data statistics and then stored the data. Due to a non-order-preserving sorting mechanism during this process, there were minor inconsistencies between the preceding and subsequent results. However, such inconsistencies do not affect the conclusions described in our paper, nor do they hinder further research conducted on this dataset.
We would like to express our gratitude again.

I see.
Anyway, thanks again for sharing this wonderful dataset!
