您好,感谢你对本工作的关注。
1)不知道你是否熟悉其他DAOD框架,由于对抗训练的不稳定性,目前几乎所有的DAOD算法的benchmark结果都是通过不公开的model selection得到的,这导致我曾经很难直接复现他们论文的结果。所以,在本工作里,与其存海量模型进行进一步model selection,不如直接让follower能直接跑出我们的结果,(我曾经花了将近一个月时间才跑出我们的baseline的论文类似结果,貌似你一次就跑出了我们差不多的结果了),而且这个做法在UDA里是基操。
2) 是的。
3)合理,你跑的应该是sim2city吧,你可以发现我们论文里汇报的是53左右,你跑出来54.7已经超过所有sota了,我们的57.1是通过详细调参以及多阶段才得到的,我们端到端训练也只能达到55左右的结果,DAOD算法非常难调且不稳定。
4) 你可以调整trainer.py里面的模型保存策略,并且自行尝试不同的迭代数(6w迭代对于DAOD真的很少,有的DAOD工作跑几十万iter寻找benchmark结果),而且由于对抗训练的不稳定性,也很难保证一次设置就合适,我们也是跑了上百个实验。
对于SIGMA的潜力能到哪,其实我们也很难说,因为我们的研究程度也有限(很多时候一个参数设置偏差就会导致性能下降),不过目前来看您已经能复现出高于我们论文汇报的结果了,后续的提升空间希望能自行探索了。
