Project Description
This project develops a privacy-preserving extraction framework using locally deployable open-weight LLMs to structure dense clinical narratives. We aim to bypass expensive and non-private cloud APIs by fine-tuning models to extract Common Data Elements (CDEs) from Orthodontic and TMJ progress notes entirely offline.
Objective
-
Fine-tune local LLMs (Llama-3.1-8B, Qwen-2.5-7B) to parse variable clinical shorthand into deterministic JSON dictionaries.
-
Benchmark these local models against cloud baselines and human inter-rater ceilings for accuracy and computational efficiency.
-
Deploy these trained models directly into 3D Slicer by developing a custom extension.
Approach and Plan
-
Fine-tune Meta-Llama-3.1-8B for orthodontic notes and Qwen-2.5-7B for TMJ records.
-
Evaluate the extractions using exact match F1-scores.
-
Build a fully offline 3D Slicer extension for secure, on-device data processing.
Progress and Next Steps
Fine-tuned Llama-3.1-8B (LoRA) achieved a 0.740 F1 score on orthodontic notes , and fully fine-tuned Qwen-2.5-7B reached a 0.78 F1 score on TMJ records.
Next Steps: Deploy these trained models directly within 3D Slicer by developing a custom extension with a dedicated user interface (UI) for clinical application.
