对比11个AutoML工具在放射组学中的表现,发现专用工具性能强但难用,通用工具易用且高效。

Automated Machine Learning in Radiomics: A Comparative Evaluation of Performance, Efficiency and Accessibility

  • 对比通用与放射组学专用AutoML框架在10个数据集上的表现
  • 专用工具Simplatab平均AUC达81.81%,通用工具LightAutoML仅6分钟完成训练
  • 当前工具缺乏生存分析支持和特征可复现性整合,需针对性改进

自动化机器学习(AutoML)框架可通过降低技术门槛,帮助无编程经验的研究者构建预测模型。然而,其在应对放射组学特定挑战方面的有效性尚不明确。本研究评估了通用型与放射组学专用AutoML框架在多种放射组学分类任务中的性能、效率与可访问性,基于10个公共/私有放射组学数据集,涵盖不同成像模态(CT/MRI)、数据规模、解剖部位及临床终点。六种通用型与五种放射组学专用框架在预设参数下使用标准化交叉验证进行测试。评估指标包括AUC、运行时间,以及软件状态、可访问性与可解释性的定性维度。结果显示,专用于放射组学的Simplatab工具在无代码界面下实现最高平均测试AUC(81.81%),运行时间约1小时;通用框架LightAutoML执行速度最快(6分钟),平均AUC为78.74%。多数放射组学专用工具因过时、编程要求高或计算效率低被排除在性能分析外。相反,通用框架表现出更高的可访问性与易用性。尽管Simplatab在性能、效率与可访问性间取得较好平衡,但仍存在显著空白:如缺乏对生存分析的支持,且未集成特征可复现性与标准化处理。未来研究应致力于将AutoML解决方案更适配放射组学的特定需求。

原文摘要 · Abstract (English)

Automated machine learning (AutoML) frameworks can lower technical barriers for predictive and prognostic model development in radiomics by enabling researchers without programming expertise to build models. However, their effectiveness in addressing radiomics-specific challenges remains unclear. This study evaluates the performance, efficiency, and accessibility of general-purpose and radiomics-specific AutoML frameworks on diverse radiomics classification tasks, thereby highlighting development needs for radiomics. Ten public/private radiomics datasets with varied imaging modalities (CT/MRI), sizes, anatomies and endpoints were used. Six general-purpose and five radiomics-specific frameworks were tested with predefined parameters using standardized cross-validation. Evaluation metrics included AUC, runtime, together with qualitative aspects related to software status, accessibility, and interpretability. Simplatab, a radiomics-specific tool with a no-code interface, achieved the highest average test AUC (81.81%) with a moderate runtime (~1 hour). LightAutoML, a general-purpose framework, showed the fastest execution with competitive performance (78.74% mean AUC in six minutes). Most radiomics-specific frameworks were excluded from the performance analysis due to obsolescence, extensive programming requirements, or computational inefficiency. Conversely, general-purpose frameworks demonstrated higher accessibility and ease of implementation. Simplatab provides an effective balance of performance, efficiency, and accessibility for radiomics classification problems. However, significant gaps remain, including the lack of accessible survival analysis support and the limited integration of feature reproducibility and harmonization within current AutoML frameworks. Future research should focus on adapting AutoML solutions to better address these radiomics-specific challenges.
