DLF: Disentangled-Language-Focused Multimodal Sentiment Analysis, AAAI 2025.

Arxiv Paper

Main Contributions

Our main contributions can be summarized as follows:

Proposed Framework: In this study, we propose a Disentangled-Language-Focused (DLF) multimodal representation learning framework to promote MSA tasks. The framework follows a structured pipeline: feature extraction, disentanglement, enhancement, fusion, and prediction.
Language-Focused Attractor (LFA): We develop the LFA to fully harness the potential of the dominant language modality within the modality-specific space. The LFA exploits the language-guided multimodal cross-attention mechanisms to achieve a targeted feature enhancement ($X$->Language).
Hierarchical Predictions: We devise hierarchical predictions to leverage the pre-fused and post-fused features, improving the total MSA accuracy.

Usage

Prerequisites

Python 3.9.13
PyTorch 1.13.0
CUDA 11.7

Installation

Create a conda environment. Please make sure you have installed conda before.

conda create -n DLF python==3.9.13

Activate the built DLF environment.

conda activate DLF

Install Pytorch with CUDA

pip install torch==1.13.0+cu117 torchvision==0.14.0+cu117 torchaudio==0.13.0 --extra-index-url https://download.pytorch.org/whl/cu117

Clone this repo.

git clone https://github.com/pwang322/DLF.git

Install the necessary packages.

cd DLF
pip install -r requirements.txt

Datasets

Data files (containing processed MOSI, MOSEI datasets) can be downloaded from here. You can first build and then put the downloaded datasets into ./dataset directory and revise the path in ./config/config.json. For example, if the processed the MOSI dataset is located in ./dataset/MOSI/aligned_50.pkl. Please make sure "dataset_root_dir": "./dataset" and "featurePath": "MOSI/aligned_50.pkl". Please note that the meta information and the raw data are not available due to the privacy of YouTube content creators. For more details, please follow the official website of these datasets.

Run the Codes

Training

You can first set the training dataset name in ./train.py as "mosei" or "mosi", and then run:

python3 train.py

By default, the trained model will be saved in ./pt directory. You can change this in train.py.

Testing

You can first set the testing dataset name in ./test.py as "mosei" or "mosi", and then test the trained model:

python3 test.py

We also provide pre-trained models for testing. (Google drive)
