Questions Regarding the Algorithm in Your Paper

[LHYUNMIN]

I was deeply impressed by your paper and found it very insightful. However, as I read through it, a few questions arose, and I would be grateful if you could clarify them.

1. For the proposed dataset, did you verify the results of each method algorithm mentioned in Table 2?

2. Did you adapt the code of each algorithm to ensure compatibility with the proposed dataset?

3. I was unable to locate the code for methods [49], [12], and [13] as listed in Table 2.

Finally, I am currently working with a custom dataset that includes both group bounding boxes and individual bounding boxes. Would it be feasible to apply the proposed algorithms in your paper to this dataset?

Your insights would be incredibly valuable to my research, and I appreciate your time and help.

Thank you for your interest.
As mentioned in the section 5.2 of our paper, most existing methods did not provide official source code, so we reproduced them and tested them on the proposed Café dataset. ARG has the official source code available (https://github.com/wjchaoGit/Group-Activity-Recognition), but for Joint, JRDB-base, and HGC, we contacted the authors, but were unable to obtain the official source code, so we do not plan to release the reproduced code.
For the final question, I believe it would be possible to apply our method to your custom dataset, though some modifications might be needed depending on the specific settings. If you need any help, feel free to contact me by email.
