pytorch_HAN

一位热心git友指出之前问题是过拟合了，修改以下utils.py相关地方得到以下结果：

Paper address:
https://github.com/Jhy1993/Representation-Learning-on-Heterogeneous-Graph
Heterogeneous Graph Attention Network (HAN) with pytorch. If you want to pursue the performance in the original paper, this may not be suitable for you, because there is still a problem: training loss decreases, but verification loss increases.

If you just want to figure out the basic principles of HAN and how to change tensorflow code to pytorch code, then this is for you. I implemented it according to the original tensorflow code structure.

If you want to pursue higher performance, please refer to:
Official tensorflow implementation:https://github.com/Jhy1993/HAN
DGL implementation:https://github.com/dmlc/dgl/tree/master/examples/pytorch/han

The result

Address of ACM data set： Preprocessed ACM can be found in: https://pan.baidu.com/s/1V2iOikRqHPtVvaANdkzROw 提取码：50k2

You can use the following command to run:

python main.py
