Information on 3 splits of action recognition pretrained models

Hello,

Thank you for this wonderful repository of pretrained model. I am extensively using gluoncv pretrained models for UCF and HMDB dataset and works great.

The common strategy used by action recognition methods is to use 3 splits for training. Are the models that are provided trained on any one of the splits? If so could you provide the details on which split the model was trained and tested on.
