Training Set have MIB group which contain different area target

Dear IntelLabs and ICCAD 2026 FloorSet organizers,

I have found that in the training set in https://huggingface.co/datasets/IntelLabs/FloorSet have tons of entry have invalid MIB groups.

By using following script to detect/reproduce the problem,
https://gist.github.com/KohakuBlueleaf/184911ab63d5a4a0a48b5a6cf7134e3a

We can find there is lot of row that have "same MIB groups id" while only the first row contain the "real MIB groups". All other row result in "the blocks that is noting in MIG group actually have different target area" which means "achiving MIB with same H,W is impossible"

We want to know if this is intended? if so, does MIB still a scoring target?

If this is not intended, will there be any updated/corrected training set?

Start with the Hugging Face FloorSet training set and run the detection script linked in the issue. Inspect rows sharing an MIB group ID and compare their real MIB groups and target areas. Done means determining whether these differing areas are intended and documenting or correcting the affected dataset entries accordingly.
