Thanks for your great work!
I am a little confused about the data preprocessing for GCS Dataset. In the paper, you used the first 3.2s (8 frames) as the observed trajectory and the next 4.8s (12 frames) as GT. However, I checked the paper [59], and found that the FPS is 25 and the annotated fps is 1.25. Thus, the time interval between two neighboring annotated frames is 1/1.25=0.8s. This means 8 steps in the past trajectory spend 8*0.8=6.4s, which is different from your paper. I am wondering if my understanding is correct.
Also, could you please release the preprocessing code or provide more details about the data preprocessing for GCS dataset (train/test split)?
Hi,
I have a question about the dimension of the Box-muller transform. In my understanding, the Box-muller transform should work on the number of samples (n)
dimension. However, in the code, it seems that you use the BM tran. on the number of feature (s)
dimension. See:
Lines 71 to 78 in 97f56cf
After line 75, loc
has the shape of n, batch size, s
.
And the bull_muller_transform()
here
Lines 7 to 14 in 97f56cf
x
, which is the s
dimension.
Please let me know if there is anything wrong with my understanding. Many thanks!
Could you please provide details on reproducing the results for the rest of the models and datasets?
Is there any particular reason you did not provide code for the other baselines and datasets?
Thanks for your great work!
But I am confused about the Box-Muller transformation. I know how to do it, but i want to know why we should do it. I'll appreciate it if you could give me an answer.
Hi,
Thanks for the nice work, I have a question regarding reproducing the numbers in Table 1 on SDD with PECNet+NPSN, which is 8.56/11.85
on minADE/minFDE.
Do you have the pretrained models, and also the training pipeline?
Thanks in advance!
