摘要:

鉴于患者信息的敏感性,生物医学领域是受人工智能(AI)和数据保护法规日益严格影响最深的领域之一。然而,合成数据生成方法的兴起为数据驱动技术提供了有前景的机遇。在本研究中,我们提出了一种适用于分类问题的合成数据生成统计方法。我们在真实世界背景下评估了由核密度估计器和K近邻采样生成的合成数据的效用和隐私影响,特别关注其在脓毒症检测中的应用。由于脓毒症进展迅速且可能危及生命,其检测是临床实践中的关键挑战。此外,我们强调了KDE-KNN与当前合成数据生成方法相比的优势。另外,我们的研究还考察了将合成数据纳入模型训练过程的影响。本研究为合成数据生成技术在缓解生物医学领域法规约束方面的有效性提供了有价值的见解。

英文摘要:

The biomedical field is among the sectors most impacted by the increasing regulation of Artificial Intelligence (AI) and data protection legislation, given the sensitivity of patient information. However, the rise of synthetic data generation methods offers a promising opportunity for data-driven technologies. In this study, we propose a statistical approach for synthetic data generation applicable in classification problems. We assess the utility and privacy implications of synthetic data generated by Kernel Density Estimator and K-Nearest Neighbors sampling (KDE-KNN) within a real-world context, specifically focusing on its application in sepsis detection. The detection of sepsis is a critical challenge in clinical practice due to its rapid progression and potentially life-threatening consequences. Moreover, we emphasize the benefits of KDE-KNN compared to current synthetic data generation methodologies. Additionally, our study examines the effects of incorporating synthetic data into model training procedures. This investigation provides valuable insights into the effectiveness of synthetic data generation techniques in mitigating regulatory constraints within the biomedical field.
