NIAT

Pytorch implementation for codes in Noise Imitation Based Adversarial Training for Robust Multimodal Sentiment Analysis (Accepted by IEEE Transactions on Multimedia). For baseline method, please see our another repo MMSA for more details, which is a scalable framework for MSA.

Noise Taxonomy

  • additive disturbance encompasses all common imperfections in multimodal applications, such as background noise in audio and visual blur in raw video clips.
    • ASR error focuses on the imperfection within the predominant linguistic modality based on the fact that transcribed text is noisy and vulnerable to attack.
    • modality feature missing, which models imperfections resulting from potential facial detection failure, transmission error with zero padding vectors and unknown word token for text.

Methodology - NIAT

one unified framework capable of achieving robust performance against four distinct forms of potential data imperfections, which include (random, temporal, and structural temporal) modality feature missing, entire modality missing, ASR error, as well as attacks on text modality, simultaneously.

Usage

For MOSI and MOSEI dataset, you need to download them Using the following link. (aligned_50.pkl). And Change the root_dataset_dir in __datasetCommonParams in config/config_regression.py.

For experiment of the asr error and sentiment word replacement, you should download the corresponding data Here.

Using the following script to run our codes.

python run.py --modelName niat --datasetName mosi

and evaluate the trained model with others type of modality feature missing.

For performance reproduce, we provided the saved model parameters. You should unzip the niat-{mosi/mosei}-method_one-0.2-{111x}.pth file from Here, and place them into saved_models/normals then run the Test.py.

python Test.py --modelName niat --datasetName mosi --noise_type [test_noise_type]
