Hi，in the paper:LightGCN which is published in SIGIR ,2020.The formula 4 means k layer embedding should multiple a weight 1/(k+1),but in your code ( model.py ,function computer), different layer embedding share the same weight. Is there anything wrong?
您好：论文里公式4，第k层的embedding是需要乘一个系数1/(k+1)再加和。但代码model.py的computer函数里，是直接将若干层的embedding取均值。请问这是什么情况？
