Clarification on differences and overlaps among dataset subsets

[yileitu]

Hi and thank you for releasing the Infinity-Instruct dataset!

I noticed several subsets listed on Hugging Face and in the dataset viewer (see screenshot below), including:

• 0625 (660k rows)
• 3M (3.46M rows)
• 7M (7.45M rows)
• 7M_core (7.45M rows)
• 7M_domains (7.45M rows)
• Gen (~1.4M rows)

Could you please clarify the following:

1. What are the differences among these subsets?
2. Are there overlaps between them? For example, is 3M a subset of 7M?
3. What distinguishes 7M, 7M_core, and 7M_domains, especially given they all have 7.45M rows?
4. What exactly is the Gen subset? Does it include examples from the above sets, or is it a separate dataset?

Any documentation or summary would be greatly appreciated. Thanks again for your great work!
