What It Does

  • +Neural topic modeling leveraging Sentence-Transformers, UMAP, and HDBSCAN
  • +Class-based TF-IDF (c-TF-IDF) for highly interpretable topic word representations
  • +Dynamic temporal topic modeling tracking how topics evolve over time

What It Does Not Do

  • -Generate free-form generative creative text
  • -Execute on microcontrollers
  • -Replace traditional transactional text search engines

>Suitable Work Types

  • Discovering emerging themes across customer feedback, survey responses, and support transcripts
  • Analyzing temporal trends in academic papers or news archives
  • Hierarchical clustering of enterprise knowledge repositories

>Unsuitable Work Types

  • Real-time microsecond document routing
  • Numerical tabular financial accounting
Data Residency Implications

In-process host and GPU memory.

Security Considerations

Safe when saving topics via SafeTensors or JSON metadata.

Operational Profile & Known Limitations

Maturity:mature
Learning Curve:low
Ops Complexity:low
Cost Tier:free-oss
> Known Limitations:
  • UMAP dimensionality reduction can introduce stochasticity unless random_state is fixed.
  • HDBSCAN clustering can produce a high volume of unassigned outlier documents (-1).
