您好!训练时长与所使用的显卡型号相关,目前并未尝试过多张GPU作训练,不过个人猜测应该对精度没太大影响。

感谢回复!那单张卡训练200epoch大概要多久呢?

另外想请问下在训练过程中打印recall,precision,hit,ndcg@20的时候为什么同步打印了@100呢?

个人测试在2080ti下训练一个epoch差不多800s;打印@100的话没有什么别的意思,作为一种性能参考。

我现在训练了70epoch,但离论文中结果还差很多,想问下一般需要跑完200epoch吗?那这样的话耗时需48小时,要是再尝试超参数调整是不是实验周期会很长呢?第一次了解这个任务,感谢指教~

一般是通过early stopping的方式来结束训练,并不限定于确定个数的epoch。我个人经验而言NGCF模型本身确实需要较长的训练时长。你可以参考下性能更优越的LightGCN。
