Python implementations of various topic modeling algorithms including LDA, collaborative topic models, and hierarchical Dirichlet processes.
python-topic-model is a Python library that implements various topic modeling algorithms for discovering latent thematic structures in text documents. It provides educational implementations of models like Latent Dirichlet Allocation (LDA), collaborative topic models, and hierarchical Dirichlet processes. The project solves the need for accessible, transparent implementations of topic modeling algorithms for learning and research purposes.
Researchers, data scientists, and students who want to understand topic modeling algorithms or need reference implementations for academic projects. It's particularly suitable for those working with text analysis who prefer transparent code over optimized production libraries.
Developers choose python-topic-model for its comprehensive collection of topic modeling implementations in one package and its educational focus with clear, inspectable code. Unlike optimized production libraries, it prioritizes algorithmic transparency and serves as a learning resource for understanding how different topic models work internally.
Implementation of various topic models
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
The code prioritizes transparency and correctness over optimization, making it ideal for learning how topic modeling algorithms work internally, as stated in the project philosophy.
Includes a wide range of topic models from basic LDA to advanced ones like Hierarchical Dirichlet Scaling Process, providing a one-stop reference for researchers, as listed in the README.
Each model comes with Jupyter notebook examples, as linked in the README, offering hands-on demonstrations and easy experimentation for learners.
For key models like LDA, it implements both collapsed Gibbs sampling and variational inference, allowing users to compare different algorithmic approaches, detailed in the feature list.
The README explicitly warns that MCMC implementations are 'extremely slow' and not recommended for large datasets, making it impractical for scaling beyond small experiments.
Beyond example notebooks, there is minimal API documentation or tutorials, which can hinder integration into complex projects and onboarding for new users.
Missing features common in production libraries, such as parallel processing or model persistence, as it focuses solely on educational clarity rather than deployment needs.
