RSGAN中负样本生成的问题 #252

请教您几个问题

物品的负样本：RSGAN.py中readNegativeFeedbacks(self)要用到/dataset/lastfm/ratings_n.txt。从 dataset文件夹缺少lastfm数据集 #193 和 Implementation and formula problems about RSGAN. #184 中我看到要自己预先生成负样本，您建议的是交互在100以下的算是负样本。那我理解把ratings.txt中第三列小于100都可以归集为负样本，是可以的吧？
社交用户的负样本：代码中通过元路径的方式在5个元路径中随机游走采样正负样本，但在正文中好像没有这部分内容的描述。我理解您是通过元路径的方式采集了用户的正负样本，这样理解对吗？

盼复，谢谢

你好，

可以的。不过我后来认为lastfm里面这个值设为100会比较高，建议设置较低的值。
元路径的设计以及描述请参考我的cikm18论文 Adaptive implicit friends identification over heterogeneous network for social recommendation
