可疑特征交互的效率. 在语句级缺陷定位中, 本文提出了一种约简的因果图模型, 该模型可以实现更精准的因果效
应评估. 此外, 通过在 6 个真实的 SPL 系统上与基准方法进行实验对比, 结果显示提出方法在单缺陷和多缺陷案
例中均表现出更优的缺陷定位效果, 说明了因果效应和频谱效应融合的必要性.
然而, FCS-FL 在处理大规模 SPL 系统时, 特征交互的搜索空间仍然是巨大的, 并且有必要在更大规模的系统
上来验证方法的有效性. 此外, 针对 SPL 缺陷的智能化修复同样也是一项重要且艰巨的任务, 但相关研究同样稀
缺. 在未来的工作中, 将考虑内部特征交互对特征级缺陷定位的影响, 以进一步缓和“组合爆炸”的影响. 此外, 计划
针对 SPL 缺陷定位任务, 构建更多高维且复杂的数据集, 尤其是复杂的多缺陷案例, 结合多级中介分析与正则化
建模策略以扩展 FCS-FL, 并在这些系统中进行验证. 最后, 拟针对 SPL 缺陷修复提出更有效的方法, 实现智能化
测试和调试的闭环.
