Could you plz explain details meaning of csv file.

I saw there are a lot of array looks like [1,1,1,1,1,1,1,1,1] and a big number like 21231 after with that, within test_loader.csv

And there are a lot of id, such as video id, instance id, entity id, and label id.

I guess video id is the clip_figure accompanied id with each related video, and entity_box_x,y is the face clip marks, but what are the meanings of the others' id?
Could you please give more details ?

Really Thanks!

The official description can be found here:
https://research.google.com/ava/download.html#ava_active_speaker_download
Instance is the name of the video, entity is the name of the clips (One video has many clips)

[1,1,1...1] is the label(1 for active, 0 for non-active). Test data does not have the label. So all the labels are 1.

The number is the length of the labels for the clip I think.

Dear Tao:
For an example, there is a line from val_loader.csv such as
HV0H6oc4Kvs_0960_1020:1 10 25.0 [0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, ] 2715

where
HV0H6oc4Kvs_0960_1020:1 is the instance_id
10 is frames
25.0 is what?
[0,0,0,0,...,1] is label_id
2715 is what?

Thanks!

25.0 is fps, notice that the fps is not always 25.0 in AVA.

2715 is the random index, you can ignore that part. That is not important. Sorry forget to mention it.
