How to split rare first datasets and non-rare datasets on HICO-DET. And please provide Unseen object list for me

[zhihou7]

Hi @yujialele , the unseen HOI categories of non-rare and rare first splits are provided in https://github.com/zhihou7/HOI-CL/blob/a23c77a410c7e3fcffbf000e87ff5fa84cc6c963/lib/ult/ult.py#L2028.

I first sorted the categories list according to the number of instances. Then I select the HOI categories from the head and tail as non-rare and rare first splits respectively. Particularly, I make sure that the factors (verb and object) of unseen HOI factories exist in the remaining categories( seen HOIs) during selection. that is, if I find there will no instances for one verb or object in the remaining HOI categories, the current HOI category will be kept, and I check the next categories for selecting as unseen categories.

For the unseen object list, it is {'toothbrush', 'frisbee', 'elephant', 'zebra', 'baseball_bat', 'skis', 'tennis_racket', 'refrigerator', 'skateboard', 'dog', 'pizza', 'clock'}. You can check it in unseen hoi list.

The unseen object splits follows https://arxiv.org/abs/1904.03181. Please notice this split will also result in unseen verbs according to my comment in this line. that is ['break', 'slide', 'move', 'flip', 'brush_with'].

Feel free to ask if you have further questions.

Thanks! I want to know how the unseen hoi category is defined in your work. I read this paper named Detecting Human-Object Interactions via Functional Generalization(https://arxiv.org/abs/1904.03181), but I find that they randomly select 12 objects. In your paper FCL, whether the unseen objects are randomly selected or not.

No，unseen objects are from their selection. It is the same as cosnet. You can treat that the unseen categories are fixed in my paper. However, As I mentioned before, current unseen object split is not much reasonable.
