about the feature extractor architecture about vac_cslr

Hi @atonyo11 ,
The equation for the receptive field calculation is RF_i = (RF_i-1) * stride + Ksize

For C5-P2-C5-P2:

-P2: (1-1)*2+2=2
-C5-P2: (2-1)*1+5=6
-P2-C5-P2: (6-1)*2+2=12
C5-P2-C5-P2: (12-1)*1+5=16

Hope this can help you understand~

Hi, thanks for your attention to our work and please feel free to post any question here,
the delta t here is implemented by conv1d on the temporal dimention with stride=1, and the implementation can be found here. The ablation results about the length of delta t can be found in the Table 4 of the main paper.

Hope can help you~

This really helps me. Thank you so much for answering my question!

Hi @ycmin95 , @fransisca25, can you explain how to calculate the delta t? For example C5-P2-C5-P2? Thank you in advance!

[atonyo11]

@ycmin95 oh, I got it. Thank you very much!

@ycmin95 I understand that the delta t is the receptive field. In your paper context, does that mean the delta t is number of frames?
