Code for ECCV 2022 paper Joint-Modal Label Denoising for Weakly-Supervised Audio-Visual Video Parsing

Paper Overview

Modality-specific label noise

The procedure of modality-specific label denoising

The results on LLP dataset

Get Started

Prepare data

1. Please download the preprocessed audio and visual features from https://github.com/YapengTian/AVVP-ECCV20.
2. Put the downloaded features into data/feats/.

Train the model

1.Train noise estimator:

python main.py --mode train_noise_estimator --save_model true --model_save_dir ckpt --checkpoint noise_estimater.pt

2.Calculate noise ratios:

python main.py --mode calculate_noise_ratio --model_save_dir ckpt --checkpoint noise_estimater.pt --noise_ratio_file noise_ratios.npz

3.Train model with label denoising:

python main.py --mode train_label_denoising --save_model true --model_save_dir ckpt --checkpoint JoMoLD.pt --noise_ratio_file noise_ratios.npz

Test

We provide the pre-trained JoMoLD checkpoint for evaluation.
Please download and put the checkpoint into "./ckpt" directory and use the following command to test:

python main.py --mode test_JoMoLD --model_save_dir ckpt --checkpoint JoMoLD.pt
