The meanings of FID_k and FID_g of groudtruth?

[by2101]

Hi authors,

Thank you for your fantastic work! I have a small question: In Table 1, FID_k, FID_g of groundtruth are reported. I am a little bit confused with this. Do they mean to compute FID_k and FID_g between the two same sets of groundtruth data? In other words, why FID_k and FID_g of the groundtruth are not 0?

Thank you, Best

Hi there! Thanks for your interests!

Referring to AIST++ benchmark [1], FID values are computed using features of generated dances and ALL real dances, which includes both training and test sets. FID of GT here regards the difference between test set GT and ALL real dances. It is a reference for the scores.
