# lfm2.5-Encoder-350M-datause-extended
Fine-tune of `LiquidAI/LFM2.5-Encoder-350M` for BIO data-use mention tagging
(dataset / survey / census / registry mentions in economics research papers).
## Labels
- `NAMED_DATA` — a proper name, title, or acronym of a specific data source
- `DESCRIPTIVE_DATA` — a source described in words but not named
- `VAGUE_DATA` — generic data wording with no identifiable source
## Training
- base model: `LiquidAI/LFM2.5-Encoder-350M`
- dataset: `rafmacalaba/data-use-mentions-extended` (bio config)
- epochs: 5
- learning rate: 2e-05
- batch size: 16
- precision: bf16
