医疗保健 AI 微调：从临床笔记到合规部署
微调医疗保健 AI 模型的端到端指南——涵盖数据去标识化、临床 NLP 训练、本地部署和合规验证。
医疗保健 AI 已过了炒作阶段。挑战在于执行——具体来说，如何从原始临床数据到部署的合规 AI 模型。
端到端管线
Clinical Notes (EHR) → De-identification → Dataset Preparation → Fine-Tuning → Evaluation → On-Premise Deployment → Compliance Validation
步骤 1：去标识化临床数据
使用 Safe Harbor 方法移除所有 18 类 PHI。工具：Microsoft Presidio、John Snow Labs、自定义 regex + NER。人工审查 5-10% 样本。
步骤 2：准备训练数据集
按任务构建：临床笔记摘要、医学编码辅助、临床信函生成。
步骤 3：微调
基础模型推荐：Llama 3.1 8B 或 BioMistral 7B。LoRA rank 32，学习率 1e-4，3-5 epochs。
步骤 4：本地部署
- 小型诊所：单台工作站 + RTX 5090 + Ollama
- 医院网络：专用服务器 + vLLM + nginx 反向代理
步骤 5：合规验证
临床准确度验证、HIPAA 合规验证、临床治理审批、文档包准备。
代理交付模式
总投产时间：4-6 周标准部署。随着管线成熟，每个后续客户更快。
