SAT-master-online.

This is a Pytorch implementation of our "Learning on Attribute-Missing Graphs" on the link prediction task.
The codes of node attribute completion task are on: https://github.com/xuChenSJTU/SAT-master-online

Requirements

networkx==2.2.
pytorch>=1.0. python>=3.5.

some notes:

1. This code is an example code for the link prediction task of our SAT paper.
2. Some example backbones and datasets are provided so that you can directly run them.
3. Note the name "NANG" appears in ours codes is exactly the name of our "SAT" method.
   "NANG" (Node Attribute Neural Generator) is an old name we used in the previous version.

How to use

This dir contains:

1. NANG's code (NANG_main.py). With special parameter setting in NANG_main.py we can get the NANG-no cross, NANG-no self and NANG-no adver in our paper.

2. Data process (precoess.py in ./data), note this file is only used for steam dataset. For cora, citeseer and pubmed, they are processed during training.

3. Examples of datasets including cora, citeseer, pubmed and steam (in ./data).

Step1: process the data, if you want to do the experiment of Steam, you need to. preprocess it first (other datasets are already processed), so check the parameter. setting and run the code in ./data/process.py using:

python process.py.

If you do not want to run the codes on steam, you can directly skip step 1 to step 2.

Step2: Check the parameter setting in NANG_main.py,
and the parameters used in our paper is as following:
-------------------------------Cora---------------------------
topK_list = [10, 20, 50].
args.dataset='cora'.
args.epoches=1000.
args.lr=0.005.
args.enc_name='GCN' or 'GAT' # choose the encoder for NANG.
args.alpha=0.2.
args.dropout=0.5.
args.patience=100.
args.neg_times=1.
args.n_gene=2 # G step.
args.n_disc=1 # D step.
args.lambda_recon=1.0 # for self stream
args.lambda_cross=10.0 # for cross stream.
args.lambda_gan=1.0 # this parameter is always 1.0, you can ignore it.

-------------------------------Citeseer---------------------------
topK_list = [10, 20, 50].
args.dataset='citeseer'.
args.epoches=1000.
args.lr=0.005.
args.enc_name='GCN' or 'GAT' # choose the encoder for NANG.
args.alpha=0.2.
args.dropout=0.5.
args.patience=100.
args.neg_times=1.
args.n_gene=2 # G step.
args.n_disc=1 # D step.
args.lambda_recon=1.0 # for self stream
args.lambda_cross=10.0 # for cross stream.
args.lambda_gan=1.0 # this parameter is always 1.0, you can ignore it.

-------------------------------Pubmed---------------------------
topK_list = [10, 20, 50] # this parameter will be useless for Pubmed.
args.dataset='pubmed'.
args.epoches=1000.
args.lr=0.005.
args.enc_name='GCN' or 'GAT' # choose the encoder for NANG.
args.alpha=0.2.
args.dropout=0.5.
args.patience=100.
args.neg_times=1.
args.n_gene=5 # G step.
args.n_disc=1 # D step.
args.lambda_recon=1.0 # for self stream
args.lambda_cross=50.0 # for cross stream.
args.lambda_gan=1.0 # this parameter is always 1.0, you can ignore it.

-------------------------------Steam---------------------------
topK_list = [3, 5, 10].
args.dataset='steam'.
args.epoches=1000.
args.lr=0.005.
args.enc_name='GCN' or 'GAT' # choose the encoder for NANG.
args.alpha=0.2
args.dropout=0.5.
args.patience=100.
args.neg_times=1.
args.n_gene=5 # G step.
args.n_disc=1 # D step.
args.lambda_recon=1.0 # for self stream.
args.lambda_cross=10.0 # for cross stream.
args.lambda_gan=1.0 # this parameter is always 1.0, you can ignore it.

If you get the right parameter setting, you can run the code using:

GPU mode:
CUDA_VISIBLE_DEVICES=GPU_num python NANG_main.py

CPU mode:
CUDA_VISIBLE_DEVICES= python NANG_main.py

Step3: After you run NANG_main.py, for Cora, Citeseer and Steam, it will directly print the link prediction results.
