Hi organizer,
You released all the annotations of HMDB/ADL/UT-Ego Dataset. I'm not sure whether these data can be used in only task 1.1 or both.
Thanks,
Chen
Hi Chen,
Thanks for your question. As stated on our white paper,
Sub-track 1.1:
- Can use any video data for training e.g. these videos not annotated in Kinetics, any web videos
- Can use supervision to train models for upstream tasks, e.g.:
object detection model trained on COCO, employ it on our Kinetics-GEBD to obtain intermediate results
action detection model trained on ActivityNet, employ it on our Kinetics-GEBD to obtain intermediate results
- In report, must specify what kind of external data or upstream supervision has been used.
Sub-track 1.2:
- Cannot use any videos NOT in our #Kinetics-GEBD#.
- Cannot use any additional supervision other than our GEBD annotations in Kinetics-GEBD. Thus, cannot use upstream task models that are trained on other dataset or annotation. (Exception: OK to use pre-trained backbone for initialization of your GEBD model)
Track 2:
(1) for our annotated #GEBD datasets (i.e. Kinetics, HMDB, ADL, UT-Ego), use 1 or multiple of them#
(2) do not use any of our annotations but use generic boundaries detected or annotated by yourselves on any dataset
(3) combination of (1) and (2) e.g. first train a GEBD model on our annotated datasets and then apply on another dataset to obtain large-scale pseudo boundary annotations for training a new model
Others - feel free to contact organizers to confirm if you are unsure
So you can use the recently released HMDB, ADL and UT-Ego GEBD annotations in Sub-track 1.1 and Track 2.
Best,
Stan
Hi Stan,
track 1.1 and track 2, i get it, Thanks!
Best,
