MMSA is a unified framework for Multimodal Sentiment Analysis.

• Train, test and compare multiple MSA models in a unified framework.
• Supports 14 MSA models, including recent works.
• Supports 3 MSA datasets: MOSI, MOSEI, and CH-SIMS.
• Easy to use, provides Python APIs and commandline tools.
• Experiment with fully customized multimodal features extracted by MMSA-FET toolkit.

Note: From version 2.0, we packaged the project and uploaded it to PyPI in the hope of making it easier to use. If you don't like the new structure, you can always switch back to v_1.0 branch.

• Run pip install MMSA in your python virtual environment.

• Import and use in any python file:

  from MMSA import MMSA_run
  
  # run LMF on MOSI with default hyper parameters
  MMSA_run('lmf', 'mosi', seeds=[1111, 1112, 1113], gpu_ids=[0])
  
  # tune TFN on MOSEI with default hyper parameter range
  MMSA_run('tfn', 'mosei', seeds=[1111], gpu_ids=[1])

• For more detailed usage, please refer to this page.

• Run pip install MMSA in your python virtual environment.

• Use from command line:

  # show usage
  $ python -m MMSA -h
  
  # train & test LMF on MOSI with default parameters
  $ python -m MMSA

• For more detailed usage, please refer to this page.

• Clone this repo and install requirements.

  $ git clone https://github.com/thuiar/MMSA

• Edit the codes to your needs. Add a new model or alter the configs, etc.
• After editing, run the following commands:

  $ cd MMSA-master # make sure you're in the top directory
  $ pip install .

• Then run the code like above sections.
• To further change the code, you need to re-install the package:

  $ pip uninstall MMSA
  $ pip install .

• If you'd rather run the code without installation(like in v_1.0), please refer to this page.

MMSA currently supports MOSI, MOSEI, and CH-SIMS dataset. Use the following links to download raw videos, feature files and label files. You don't need to download raw videos if you're not planning to run end-to-end tasks.

• All files: BaiduYun Disk
• Feature and label files only: Google Drive

MMSA uses feature files that are organized as follows:

{
    "train": {
        "raw_text": [],              # raw text
        "audio": [],                 # audio feature
        "vision": [],                # video feature
        "id": [],                    # [video_id$_$clip_id, ..., ...]
        "text": [],                  # bert feature
        "text_bert": [],             # word ids for bert
        "audio_lengths": [],         # audio feature lenth(over time) for every sample
        "vision_lengths": [],        # same as audio_lengths
        "annotations": [],           # strings
        "classification_labels": [], # Negative(0), Neutral(1), Positive(2). Deprecated in v_2.0
        "regression_labels": []      # Negative(<0), Neutral(0), Positive(>0)
    },
    "valid": {***},                  # same as "train"
    "test": {***},                   # same as "train"
}

Note: For MOSI and MOSEI, the pre-extracted text features are from BERT, different from the original glove features in the CMU-Multimodal-SDK.
