An API-oriented Python framework for unsupervised learning on graphs, featuring node/graph embeddings and community detection.
Karate Club is an open-source Python framework for unsupervised learning on graph-structured data. It provides a comprehensive collection of algorithms for graph embedding, community detection, and graph-level representation learning, acting as a Swiss Army knife for graph mining tasks. The framework integrates seamlessly with NetworkX, offering a unified API to apply state-of-the-art techniques from network science and machine learning conferences.
Researchers and data scientists working on graph mining, network analysis, or unsupervised learning who need a reliable library to experiment with advanced graph algorithms without building them from scratch.
Karate Club stands out by consolidating a wide range of graph algorithms into a single, easy-to-use package with a consistent API, saving time on implementation and enabling rapid prototyping. Its tight integration with NetworkX and coverage of recent research makes it a go-to tool for graph-based machine learning projects.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements over 30 state-of-the-art methods from top conferences like KDD and NeurIPS, covering node embeddings, community detection, and graph-level representations, as detailed in the README's comprehensive list.
Works directly with NetworkX graphs, leveraging its familiar API for easy graph manipulation and analysis, as shown in the example where a NetworkX graph is passed to the fit method.
Includes methods like FEATHER-N and MUSAE that handle graphs with node attributes, combining structural and feature information for advanced analysis.
Offers thorough documentation, examples, and has CI/CD badges indicating active maintenance, code coverage, and regular updates.
Designed for small-scale graph mining research, as noted in the description, and not optimized for large networks, which can hinder performance on big data applications.
Lacks algorithms for graphs that change over time, such as streaming social networks, limiting its use in real-world scenarios where data evolves.
While convenient for NetworkX users, it restricts integration with other graph frameworks like PyTorch Geometric or DGL, potentially complicating workflows in diverse ecosystems.
Excludes supervised graph learning techniques, such as GNNs, which are essential for many modern graph-based prediction tasks and may require additional libraries.
