Highlights
- Staged, cost-aware text-to-SQL: identify relevant tables from the top-layer schema first, then send detailed schema only for those, with a clarification loop.
- Call-transcript problem-type extraction with Llama 2 and a TF-IDF matrix for partial product-model keywords.
- Retail sales forecasting design (LightGBM quantile, TFT/N-HiTS, promo uplift and elasticity); small OpenAI-backed agent tools.
