Base Model and Dataset: DeepSeek-R1 and medical-o1-reasoning-SFT

Base Model and Dataset: DeepSeek-R1 and medical-o1-reasoning-SFT

DeepSeek-R1-Distill-Llama-8B was chosen for its optimized reasoning capabilities and balanced performance-efficiency at the 8B scale. The medical-o1-reasoning-SFT dataset is used, which contains rich medical cases and "chain-of-thought" reasoning processes to help the model learn medical reasoning logic.

Fine-tuning Strategy and Technical Implementation: From General to Medical Expertise

Fine-tuning Strategy and Technical Implementation: From General to Medical Expertise

A supervised fine-tuning (SFT) strategy is adopted, with steps including data preprocessing, training configuration, training loop, and evaluation. Conservative strategies (low learning rate, early stopping) are used to prevent overfitting. The open-source Notebook ensures reproducibility of the process and supports community modifications and extensions.

Application Scenarios and Limitations: Positioning as an Auxiliary Tool and Ethical Considerations

Application Scenarios and Limitations: Positioning as an Auxiliary Tool and Ethical Considerations

Application scenarios include medical education (virtual case partners), clinical decision support (assisting doctors), and medical research (literature screening), but it should be used as an auxiliary tool. Limitations include data bias and insufficient interpretability. Ethically, attention should be paid to privacy, responsibility attribution, and fairness.
