Multivariate, Multi-frequency and Multimodal: Rethinking Graph Neural Networks for Emotion Recognition in Conversation

Pytorch implementation for the paper: Multivariate, Multi-frequency and Multimodal: Rethinking Graph Neural Networks for Emotion Recognition in Conversation, CVPR 2023.

Requirements

• Python 3.8.5
• torch 1.7.1
• CUDA 11.3
• torch-geometric 1.7.2

Dataset

The raw data can be found at IEMOCAP and MELD.

In our paper, we use pre-extracted features. The multimodal features (including RoBERTa-based and GloVe-based textual features) are available at here.

Testing and Checkpoints

The implementation results may vary with training machines and random seeds. We suggest that one can try different random seeds for better results.

We also provide some pre-trained checkpoints on RoBERTa-based IEMOCAP at here.

For instance, to test on IEMOCAP using the checkponts:

python -u train.py --base-model 'GRU' --dropout 0.5 --lr 0.0001 --batch-size 16 --graph_type='hyper' --epochs=0 --graph_construct='direct' --multi_modal --mm_fusion_mthd='concat_DHT' --modals='avl' --Dataset='IEMOCAP' --norm BN --testing

Training examples

To train on IEMOCAP:

python -u train.py --base-model 'GRU' --dropout 0.5 --lr 0.0001 --batch-size 16 --graph_type='hyper' --epochs=80 --graph_construct='direct' --multi_modal --mm_fusion_mthd='concat_DHT' --modals='avl' --Dataset='IEMOCAP' --norm BN --num_L=3 --num_K=4

To train on MELD:

python -u train.py --base-model 'GRU' --dropout 0.4 --lr 0.0001 --batch-size 16 --graph_type='hyper' --epochs=15 --graph_construct='direct' --multi_modal --mm_fusion_mthd='concat_DHT' --modals='avl' --Dataset='MELD' --norm BN --num_L=3 --num_K=3
