[ICCV-2023] Class-Incremental Grouping Network for Continual Audio-Visual Learning

CIGN is a novel framework can directly learn category-wise semantic features to achieve continual audio- visual learning.

Environment

To setup the environment, please simply run

pip install -r requirements.txt

Datasets

VGG-Instruments

Data can be downloaded from Mix and Localize: Localizing Sound Sources in Mixtures

VGG-Sound Source

Data can be downloaded from Localizing Visual Sounds the Hard Way

Train

For training the CIGN model, please run

python train_avctl.py --multiprocessing_distributed \
    --port 12345 \
    --train_data_path /path/to/datasets/vgginstruments/train/ \
    --test_data_path /path/to/datasets/vgginstruments/train/ \
    --experiment_name_pre vgginstruments_g0_baseline_e20 \
    --experiment_name vgginstruments_g1_baseline_e20_v3_true \
    --resume_av_token \
    --train_stage 1 --test_stage 1 \
    --model 'avctl' \
    --trainset 'vgginstruments_group_0,vgginstruments_group_1' --num_class 18 \
    --testset 'vgginstruments_group_0,vgginstruments_group_1' \
