摘要:

我们介绍了一种用于多结果因果图的可视化分析方法,即多结果因果图。多结果因果图在医疗领域用于理解多病共存和共病。为了支持可视化分析,我们与医学专家合作,设计了两种比较可视化技术,分别用于分析过程的不同阶段。首先,提出了一种渐进可视化方法,用于比较多种最先进的因果发现算法。该方法可以处理混合类型的数据集,包括连续和分类变量,并帮助创建单个结果的精细调整因果图。其次,设计了一种比较图布局技术和专门的视觉编码,用于快速比较多个因果图。在我们的可视化分析方法中,分析员首先为每个结果变量构建单独的因果图,然后使用我们的比较技术生成并可视化多结果因果图,以分析这些因果图的差异和共同点。评估包括对基准数据集的定量测量、与医学专家的案例研究以及使用真实世界健康研究数据的专家用户研究。

英文摘要:

We introduce a visual analysis method for multiple causal graphs with different outcome variables, namely, multi-outcome causal graphs. Multi-outcome causal graphs are important in healthcare for understanding multimorbidity and comorbidity. To support the visual analysis, we collaborated with medical experts to devise two comparative visualization techniques at different stages of the analysis process. First, a progressive visualization method is proposed for comparing multiple state-of-the-art causal discovery algorithms. The method can handle mixed-type datasets comprising both continuous and categorical variables and assist in the creation of a fine-tuned causal graph of a single outcome. Second, a comparative graph layout technique and specialized visual encodings are devised for the quick comparison of multiple causal graphs. In our visual analysis approach, analysts start by building individual causal graphs for each outcome variable, and then, multi-outcome causal graphs are generated and visualized with our comparative technique for analyzing differences and commonalities of these causal graphs. Evaluation includes quantitative measurements on benchmark datasets, a case study with a medical expert, and expert user studies with real-world health research data.
