Retrieval-Augmented Classification of Environmental Mitigations in Hydropower Licensing Documents
TL;DR
A novel Retrieval-Augmented Generation (RAG) pipeline was developed to classify environmental mitigation obligations in hydropower licensing documents, achieving a Micro F1 score of 0.524. This hybrid approach outperformed traditional BERT-only and RAG-only methods, particularly in handling scarce label categories.
✦ Why It Matters
Consider implementing hybrid classification systems to enhance performance in data-scarce environments.
Key Takeaways
- Explore hybrid models for classification tasks with limited training data.
- Utilize RAG techniques to improve zero-shot learning capabilities.
- Assess the performance of models using Micro F1 scores.
- Integrate domain-specific knowledge into AI classification systems.
How It Works
The hybrid system combines BERT's ability to detect relevant text with RAG's capacity to classify based on retrieved definitions. This allows the model to generalize better across categories, even those with no training examples.
