This is the final selected PIIBench model: a standard DeBERTa-v3-base token classifier trained directly on the prepared multi-source PII benchmark splits. It outperformed the source-conditioned hierarchical comparison model on the complete held-out experiment test split.
This model is released with the paper:
Fine-Tuning Over Architectural Complexity: Broad-Coverage PII Detection on PIIBench with DeBERTa
arXiv: https://arxiv.org/abs/2605.25816
Hugging Face Papers: https://huggingface.co/papers/2605.25816
This repository corresponds to the direct fine-tuned DeBERTa model reported as the final selected model in the paper.
The reported evaluation uses the later prepared PIIBench experiment variant
with 82 retained entity types and a held-out test split of 100,002 records.
It is not the earlier 48-type Hub dataset release.
| Held-Out Evaluation | Records | F1 | Precision | Recall |
|---|---|---|---|---|
| Corrected heldout subset | 5,000 | 0.6476 | 0.6300 | 0.6662 |
| Complete experiment test split | 100,002 | 0.6455 | 0.6277 | 0.6645 |

This is a standard Transformers token-classification model:
from transformers import pipeline

aggregation_strategy="simple",
)
