NL→SQL intent classifier

Fine-tuned bert-base-uncased that labels a natural-language data question with the kind of SQL it needs: aggregate, compare, count, filter, trend. It routes questions in the RAG-assisted natural-language-to-SQL system and picks the chart type.

• —Training data: 1,000 of the 2,000 domain-neutral questions in the repo's data/intent_dataset.csv (400 per intent, 14 domains); the other 1,000 are the validation split.
• —Validation accuracy: 100.0%. That split is templated like the training data, so it says little; on 150 hand-written hard questions the model scores 84.7%, and 75% on questions from an unseen SaaS domain (see the repo's README).
