Hi，抱歉呢我没测试过NGCF在movielen-1m上的性能，你试过其他方法在movielen-1m上的表现么，例如LightGCN或者非图卷积的算法。

感谢您的回复，昨天看到你的回复后我就在lightGCN上运行了一次，好像也是这个0.5几结果... 其实包括我用在我自己的论文(gnn方法)上也是差不多是这个结果...https://github.com/kuandeng/LightGCN，另外 我看过MKRhttps://github.com/hwwang55/MKR以及序列推荐方法Caser的论文Precision@10都没超过0.1几， 我现在有点搞不懂了....

抱歉迟复，我也不太确定呢，其实同一个数据集在不同场景下也不好直接比较，因为用到的loss和任务可能都不同。此外lightgcn和ngcf的评价指标计算应该都是没问题的，如果你换更大规模的movielen呢？
