Features

MGTCOM Framework is meant to be used as a community detection algorithm in temporal multimodal graphs. The framework learns temporally and topologically aware embeddings and detects communities in tandem.

Implemented baselines:

• GraphSAGE¹
• Node2Vec²
• ComE³
• GEMSEC⁴
• CP-GNN⁵
• CTDNE⁶
• Metapath2Vec⁷

Model Variants

• MGTCOM: Learns temporal and topological embeddings
• MGTCOM Topo: Learns topological embeddings
• MGTCOM Tempo: Learns temporal embeddings

Used Datasets

• DBLP⁸
• ICEWS⁹
• IMDB5000¹⁰
• SocialDistancingStudents¹¹
• Cora¹²
• PubMed¹²

Installation

You can use MGTCOM models by either setting it up using Docker or by installing it manually.

Docker Installation

• Install Docker and Docker Compose
• Build the Docker image: docker-compose build
• Run scripts as docker-compose run mgtcom <script name>

Manual Installation

System Requirements:

Note that while conda installs most of the compiled dependencies, the system still needs to have an up-to-date glibc version (2.27 and up).

Check your version using following command ldd --version

• Install either Anaconda, Miniconda, or Mamba (recommended).
• Set up the environment:
  • mamba env update --prefix=./env --f environment.yml --prune
  • For cpu only usage replace pytorch::cudatoolkit=11.3 with pytorch::cpuonly in the environment.yml file.
• Activate the environment: source activate.sh

Loading dataset

• Extract preprocessed datasets:
  • Download the preprocessed datasets from Drive
  • mkdir -p ./storage/cache/dataset
  • cp ./datasets.zip ./storage/cache/dataset/datasets.zip
  • cd ./storage/cache/dataset && unzip datasets.zip

Examples

The executors are found in ml/ml/executors directory.

Viewing parameters of an axecutor:

python ml/ml/executors/mgcom_combi_executor.py -h

# For docker users
docker-compose run mgtcom ml/ml/executors/mgcom_combi_executor.py -h

Running an axecutor:

python ml/ml/executors/mgcom_combi_executor.py --repr_dim=64

# For docker users
docker-compose run mgtcom ml/ml/executors/mgcom_combi_executor.py --repr_dim=64
