Graph Robustness Benchmark (GRB) provides scalable, unified, modular, and reproducible evaluation on the adversarial robustness of graph machine learning models. GRB has elaborated datasets, unified evaluation pipeline, modular coding framework, and reproducible leaderboards, which facilitate the developments of graph adversarial learning, summarizing existing progress and generating insights into future research.

Usage of GRB Modules

Training a GML model

An example of training Graph Convolutional Network (GCN) on grb-cora dataset.

import torch  # pytorch backend
from grb.dataset import Dataset
from grb.model.torch import GCN
from grb.trainer.trainer import Trainer

# Load data
dataset = Dataset(name='grb-cora', mode='easy',
                  feat_norm='arctan')
# Build model
model = GCN(in_features=dataset.num_features,
            out_features=dataset.num_classes,
            hidden_features=[64, 64])
# Training
adam = torch.optim.Adam(model.parameters(), lr=0.01)
trainer = Trainer(dataset=dataset, optimizer=adam,
                  loss=torch.nn.functional.nll_loss)
trainer.train(model=model, n_epoch=200, dropout=0.5,
              train_mode='inductive')

Adversarial attack

An example of applying Topological Defective Graph Injection Attack (TDGIA) on trained GCN model.

from grb.attack.injection.tdgia import TDGIA

# Attack configuration
tdgia = TDGIA(lr=0.01, 
              n_epoch=10,
              n_inject_max=20, 
              n_edge_max=20,
              feat_lim_min=-0.9, 
              feat_lim_max=0.9,
              sequential_step=0.2)
# Apply attack
rst = tdgia.attack(model=model,
                   adj=dataset.adj,
                   features=dataset.features,
                   target_mask=dataset.test_mask)
# Get modified adj and features
adj_attack, features_attack = rst

GRB Evaluation

Evaluation scenarios (Injection attack as an example)

GRB provides unified evaluation scenarios for fair comparisons between attacks and defenses. The example scenario is Black-box, Evasion, Inductive, Injection.

• Black-box: Both the attacker and the defender have no knowledge about the applied methods each other uses.
• Evasion: Models are already trained in trusted data (e.g. authenticated users), which are untouched by the attackers but might have natural noises. Thus, attacks will only happen during the inference phase.
• Inductive: Models are used to classify unseen data (e.g. new users), i.e. validation or test data are unseen during training, which requires models to generalize to out of distribution data.
• Injection: The attackers can only inject new nodes but not modify the target nodes directly. Since it is usually hard to hack into users' accounts and modify their profiles. However, it is easier to create fake accounts and connect them to existing users.

GRB Leaderboards

GRB maintains leaderboards that permits a fair comparision across various attacks and defenses. To ensure the reproducibility, we provide all necessary information including datasets, attack results, saved models, etc. Besides, all results on the leaderboards can be easily reproduced by running the following scripts (e.g., [leaderboard for grb-cora dataset](https://cogdl.ai/grb/leaderboard/cora, compatible with v0.1.0)):

sh run_leaderboard_pipeline.sh -d grb-cora -g 0 -s ./leaderboard -n 0
Usage: run_leaderboard_pipeline.sh [-d <string>] [-g <int>] [-s <string>] [-n <int>]
Pipeline for reproducing leaderboard on the chosen dataset.
    -h      Display help message.
    -d      Choose a dataset.
    -s      Set a directory to save leaderboard files.
    -n      Choose the number of an attack from 0 to 9.
    -g      Choose a GPU device. -1 for CPU.
