5. Input Data and Commands for GraphSAGE to Generate Feature Matrices

GT: Dolphin, GB: Karate [data]

GT: p2p-Gnutella08, GB: Price 2[data]

GT: LC-multiple, GB: Combined-AP/MS [data]

GT: School-Day2, GB: School-Day1 [data]

To generate feature matices with GraphSAGE, use commands below after setting up GraphSAGE. Change DATA_DIR/FILE_PREFIX based on your file path (e.g., ./data/dolphin-karate)

>>> python -m graphsage.unsupervised_train --train_prefix DATA_DIR/FILE_PREFIX --model graphsage_maxpool --max_total_steps 1000 --validate_iter 10 --dim_1 12 --dim_2 12 --base_log_dir .

Indices in a generated data include both GT and GB. Indices from 0 to (nT-1) correspond to nodes in GT. Indices from nT to (nT + nB-1) correspond to nodes in GB.

6. Learned Feature Matrices with DeepGL / GraphSAGE

GT: Dolphin, GB: Karate [DeepGL][GraphSAGE]

GT: Price, GB: Random [DeepGL][GraphSAGE]

GT: Random, GB: Price [DeepGL][GraphSAGE]

GT: p2p-Gnutella08, GB: Price 2 [DeepGL][GraphSAGE]

GT: p2p-Gnutella08, GB: Enhanced Price [DeepGL]

GT: LC-multiple, GB: Combined-AP/MS [DeepGL][GraphSAGE]

GT: School-Day2, GB: School-Day1 [DeepGL][GraphSAGE]

Each learned feature matrix with DeepGL contains

*_tg.npy: feature matrix of GT

*_bg.npy: feature matrix of GB

*.feat_defs.npy: learned feature definitions

Each learned feature matrix with GraphSAGE contains

*_tg_bg.npy: feature values for each node of both GT and GB

*_node_id.txt: node indices corresponding to lines of *_tg_bg.npy. Indices from 0 to (nT-1) correspond to nodes in GT. Indices from nT to (nT + nB-1) correspond to nodes in GB.

.npy file can be loaded with NumPy: numpy.load(FILE_PATH)
