# TrustDoc Field Extractor

LayoutLMv3-base fine-tuned for token classification (HEADER/QUESTION/ANSWER field extraction on
forms), part of the TrustDoc project -- a document AI trust layer with calibrated confidence for
human-in-the-loop review.

- **Base model:** [microsoft/layoutlmv3-base](https://huggingface.co/microsoft/layoutlmv3-base)
  (CC BY-NC-SA 4.0 -- **non-commercial use only**, inherited by this fine-tune)
- **Training data:** [nielsr/funsd-layoutlmv3](https://huggingface.co/datasets/nielsr/funsd-layoutlmv3)
  (149 train / 50 test forms)
- **Test set micro-avg F1:** 0.862

## Limitations

FUNSD is a small (199-document) benchmark of noisy scanned forms -- strong results here don't
guarantee generalization to arbitrary document layouts. See the TrustDoc repo for the full
pipeline (OCR -> classify -> extract -> calibrate) and its limitations.
