Comparison on THUMOS14

[Thoudancer]

Hi, I am inspired much by your work, but confused about some details.
In Table 4 of your paper, there are some experiments on THUMOS14.
I'd like to know what exactly the train data and test data are.
Because the train data of THUMOS14 is UCF101.
Or the used train data is the 1010 validation dataset and testdata is 1574 test set?
Did you use the background data?

Look forward to your reply. Thanks
