封闭源代码的大型语言模型 (LLMs) 在日本放射学委员会考试 (JRBE) 中表现更好,而不是开源模型. 将问题翻译成英语提高了LLM准确性,成本较高的模型显示出更高的性能.
科学领域:
- 医疗教育中的人工智能
- 在放射学中使用自然语言处理.
- 机器学习用于董事会考试
背景情况:
- 日本放射学委员会考试 (JRBE) 评估放射科医生的基本知识.
- 在专业医疗检查中评估大语言模型 (LLM) 的有效性至关重要.
- 了解基于模型类型 (开源与封闭源) 和语言的LLM性能变化是关键.
研究的目的:
- 评估各种LLM在回答JRBE问题的有效性.
- 在JRBE上比较开源和封闭源LLM的性能.
- 在这种情况下,研究语言 (日语与英语翻译) 对LLM成绩的影响.
主要方法:
- 管理了315个JRBE问题 (2021-2023) 给14个LLM (7个开源,7个封闭源).
- 评估模型使用原始的日语问题和LLM翻译的英语版本.
- 使用Python分析了包括中位数,IQR,P值和相关系数在内的性能指标.
主要成果:
- 封闭源代码的LLM实现了比开源模型高50.2%的正确答案率 (44.28%对比29.52%,P<0.001).
- 将问题翻译成英语使得中位数提高了21.1% (33.02%至40.00%,P = 0.005).
- 较高的LLM成本与准确性正相关 (r = 0.613-0.623,P < 0.020);发布日期没有显著影响性能.
结论:
- 高端,封闭源代码的LLM在JRBE上表现出卓越的表现.
- 通过LLM的英语翻译问题提高了这些模型的准确性.
- LLM成本是表现的重要预测因素,而模型年龄不是.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
