想请教下, Squeeze论文里面准确率比较的那些其他方法是如何实现的? #8

您好:
如题
IDice和Apriori似乎不是精准匹配这个问题,把这两个用过来似乎是不是需要一些特殊技巧;
R-Adtributer按照原本他论文的方法不太容易得出形如A,B数据集这种形式的结果;
HotSpot好像没有开源;
这些都在Squeeze论文里面计算出来了在A,B数据集上的f1-score。
请问下可否分享一下实现方式,或者开放代码。

Apriori用于这个问题是参考这篇论文: Detecting and Localizing End-to-End Performance Degradation for Cellular Data Services Based on TCP Loss Ratio and Round Trip Time. 具体来说就是对所有的leaf attribute combination做一次异常检测, 然后用apriori算法去找attribute combination -> 异常这样的关联规则.
iDice整体问题是我们关注的问题的一个子问题, 还是适用的. 只是它里面的几个剪枝策略, 尤其是Impact based Pruning, 需要确认下是否和你具体用的数据适配. 比如如果不是#issues, 而是类似成功率这样的指标, 那Impact based Pruning很明显就不适用, 去掉就行了.
R-Adtributor就是递归调用adtributor, 我不太清楚你说的“不太容易得出形如A,B数据集这种形式的结果”具体指的是什么.
这些对比算法都没有开源的, 我就是按对论文的理解自己实现的, 也不能保证和作者的原始实现一样.
