## Model Description
|
4 |
|
5 |
+
This model is the few-shot trained calibrative fine-tuned version of Multi-CONFE (Confidence-Aware Medical Feature Extraction), built on [unsloth/Mistral-Nemo-Instruct-2407-bnb-4bit](https://huggingface.co/unsloth/Mistral-Nemo-Instruct-2407-bnb-4bit). It demonstrates exceptional data efficiency by achieving near state-of-the-art performance while training on only 12.5% of the available data, with particular emphasis on confidence calibration and hallucination reduction.
|
6 |
|
7 |
+
## Intended Use
|
8 |
|
9 |
+
This model is designed for extracting clinically relevant features from medical patient notes with high accuracy and well-calibrated confidence scores in low-resource settings. It's particularly useful for automated assessment of medical documentation, such as USMLE Step-2 Clinical Skills notes, when training data is limited.
|
10 |
|
11 |
+
## Training Data
|
12 |
|
13 |
+
The model was trained on just 100 annotated patient notes (12.5% of the full dataset) from the [NBME - Score Clinical Patient Notes](https://www.kaggle.com/competitions/nbme-score-clinical-patient-notes) Kaggle competition dataset. This represents approximately 10 examples per clinical case type. The dataset contains USMLE Step-2 Clinical Skills patient notes covering 10 different clinical cases, with each note containing expert annotations for multiple medical features that need to be extracted.
|
14 |
|
15 |
+
## Training Procedure
|
16 |
|
17 |
+
Training involved a two-phase approach:
|
18 |
+
1. **Instructive Few-Shot Fine-Tuning**: Initial alignment of the model with the medical feature extraction task using Mistral Nemo Instruct as the base model.
|
19 |
+
2. **Calibrative Fine-Tuning**: Integration of confidence calibration mechanisms, including bidirectional feature mapping, complexity-aware confidence adjustment, and dynamic thresholding.
|
20 |
|
21 |
+
Training hyperparameters:
|
22 |
+
- Base model: unsloth/Mistral-Nemo-Instruct-2407-bnb-4bit
|
23 |
+
- LoRA rank: 32
|
24 |
+
- Training epochs: 14 (instructive phase) + 5 (calibrative phase)
|
25 |
+
- Learning rate: 2e-4 (instructive phase), 1e-4 (calibrative phase)
|
26 |
+
- Optimizer: AdamW (8-bit)
|
27 |
+
- Hallucination weight: 0.2
|
28 |
+
- Missing feature weight: 0.5
|
29 |
+
- Confidence threshold: 0.7
|
30 |
|
31 |
+
## Performance
|
|
|
|
|
|
|
|
|
|
|
|
|
32 |
|
33 |
+
On the USMLE Step-2 Clinical Skills notes dataset:
|
34 |
+
- Precision: 0.982
|
35 |
+
- Recall: 0.964
|
36 |
+
- F1 Score: 0.973
|
37 |
|
38 |
+
The model achieves this impressive performance with only 12.5% of the training data used for the full model, demonstrating exceptional data efficiency. It reduces hallucination by 84.9% and missing features by 85.0% compared to vanilla models. This makes it particularly valuable for domains where annotated data may be scarce or expensive to obtain.
|
39 |
|
40 |
+
## Limitations
|
|
|
|
|
41 |
|
42 |
+
- The model was evaluated on standardized USMLE Step-2 Clinical Skills notes and may require adaptation for other clinical domains.
|
43 |
+
- Some errors stem from knowledge gaps in specific medical terminology or inconsistencies in annotation.
|
44 |
+
- Performance on multilingual or non-standardized clinical notes remains untested.
|
45 |
+
- While highly effective, it still performs slightly below the full-data model (F1 score 0.973 vs. 0.981).
|
46 |
|
47 |
+
## Ethical Considerations
|
48 |
|
49 |
+
Automated assessment systems must ensure fairness across different student populations. While the calibration mechanism enhances interpretability, systematic bias testing is recommended before deployment in high-stakes assessment scenarios. When using this model for educational assessment, we recommend:
|
50 |
|
51 |
+
1. Implementing a human-in-the-loop validation process
|
52 |
+
2. Regular auditing for demographic parity
|
53 |
+
3. Clear communication to students about the use of AI in assessment
|
