关于FDG及failure units的若干疑问 #5

@adverbial39

Description

@adverbial39
  1. 每个failure units的metric是怎么选定的?
    the experienced engineers of an online service system can define the candidate failure units by summarizing the indicative metric groups on different component classes. 可否理解为每个failure units的指标群是人工选择的?
  2. 为什么不能用GCN(3.3)
    您在论文中提到“ For generalizability, the feature aggregator should be structure-independent. Thus, graph convolutional network (GCN) [29] is unsuitable.”能否详细解释一下为什么要考虑structure-independent
  3. FDG是如何生成和更新的
    您在论文中有提到组件、部署关系会经常改变,这意味着FDG需要经常更新,这部分更新使利用专家经验完成吗?
  4. FDG是无向图,如何反应依赖/传播关系
    无向图表达相互影响,而非单方面影响(依赖),为什么能反应依赖关系呢?

期待您的解答(╹▽╹)
