Experiments

To run experiments with a single GPU.

UCF101 (split: 1, 2 or 3)

cd code
python run_net.py \
    --cfg_file configs/ucf101/config.yaml \
    --configuration ucf101 \
    --pretrain_checkpoint_path checkpoints/checkpoint.pyth \
    TRAIN.DATASET_SPLIT <split>
    TEST.DATASET_SPLIT <split>

ESC-50 (split: 1, 2, 3, 4 or 5)

cd code
python run_net.py \
    --cfg_file configs/esc50/config.yaml \
    --configuration esc50 \
    --pretrain_checkpoint_path checkpoints/checkpoint.pyth \
    TRAIN.DATASET_SPLIT <split>
    TEST.DATASET_SPLIT <split>

Kinetics-Sounds

cd code
python run_net.py \
    --cfg_file configs/kinetics-sounds/config.yaml \
    --configuration kinetics-sounds \
    --pretrain_checkpoint_path checkpoints/checkpoint.pyth

After submission, we further adjusted hyperparameters and achieved the following results.
