will 1st-5th groups C3D weights modified via back-propagation?

[rambleramble]

It seems that the 1st-5th group won't be changing weights during the training since there is a pre-trained model in your description below:
"The C3D model weight pretrained on Sports1M and finetuned on ActivityNet dataset"

Is this a correct understanding?
Can you provide a more comprehensive expalantion about "end-to-end", in terms of training via back-propagation? For instance, maybe we can use your paper's Fighure 2 as a reference.
Thanks a lot!

The learning rate at these layers can also be open. But the training time will increase. It is a trade-off.
