Abstract

Purpose

Reliability of LLM-based AI chatbots can be enhanced by using domain-specific models with a controlled knowledge base, especially relevant in the context of education and training of healthcare professionals and researchers. The aim was to produce an LLM data model with the goal of continuous education in radiation protection, that allows users to access reliable scientific information by querying it on specific topics, eliminating the need for manually perusing educational materials.

Method

A domain-specific LLM data model was developed and trained using custom knowledge from several domains, tested applying various test scenarios, and fine-tuned to ensure optimal selections of hyperparameters including top k, chunk size, temperature, max tokens etc.

Results

The final model produced reliable and accurate answers to a variety of users and queries based on controlled educational materials. Embedding model and similarity cutoff had the greatest impact on model performance.

Conclusion

The developed model was trained and validated on radiation protection training material, allowing users to access information on topics including radiobiology and radiation protection in a quick and reliable manner.
基于大型语言模型的辐射防护继续教育环境感知综合培训模块的开发
基于法学硕士的人工智能聊天机器人的可靠性可以通过使用具有受控知识库的特定领域模型来增强,特别是在医疗保健专业人员和研究人员的教育和培训背景下。目的是产生一个法学硕士数据模型,其目标是继续进行辐射防护教育,允许用户通过查询特定主题来访问可靠的科学信息,从而消除手动阅读教育材料的需要。方法使用来自多个领域的自定义知识开发和训练特定领域的LLM数据模型,应用各种测试场景进行测试,并进行微调以确保超参数的最佳选择,包括top k,块大小,温度,最大令牌等。结果最终模型根据受控的教育材料为各种用户和查询生成可靠和准确的答案。嵌入模型和相似截断对模型性能的影响最大。结论所开发的模型经过辐射防护培训材料的训练和验证,使用户能够快速、可靠地获取辐射生物学和辐射防护等主题的信息。
