Overview

GraphWar: Arms Race in Graph Adversarial Learning

NOTE: GraphWar is still in the early stages and the API will likely continue to change.

πŸš€ Installation

Please make sure you have installed PyTorch and Deep Graph Library(DGL).

# Comming soon
pip install -U graphwar

or

# Recommended
git clone https://github.com/EdisonLeeeee/GraphWar.git && cd GraphWar
pip install -e . --verbose

where -e means "editable" mode so you don't have to reinstall every time you make changes.

Get Started

Assume that you have a dgl.DGLgraph instance g that describes you dataset.

A simple targeted attack

from graphwar.attack.targeted import RandomAttack
attacker = RandomAttack(g)
attacker.attack(1, num_budgets=3) # attacking target node `1` with `3` edges 
attacked_g = attacker.g()
edge_flips = attacker.edge_flips()

A simple untargeted attack

from graphwar.attack.untargeted import RandomAttack
attacker = RandomAttack(g)
attacker.attack(num_budgets=0.05) # attacking the graph with 5% edges perturbations
attacked_g = attacker.g()
edge_flips = attacker.edge_flips()

  • Benchmark Results of Attack Performance

    Benchmark Results of Attack Performance

    Hi, thanks for sharing the awesome repo with us! I recently run the attack sample code but the resultpgd_attack.py and random_attack.py under examples/attack/untargeted, but the accuracies of both evasion and poison attack seem not to decrease.

    I'm pretty confused by the attack results. For CV models, pgd attack easily decreases the accuracy to nearly random guesses, but the results of GreatX seem not to consent with CV models. Is it because the number of the perturbed edges is too small?

    Here are the results of pgd_attack.py

    SG Attack example cannot run as expected on cuda

    Hello, I got some error when I run SG Attack's example code on cuda device:

    Traceback (most recent call last):
      File "src/test.py", line 50, in <module>
        attacker.attack(target)

        self.label == best_wrong_label)[0].cpu().numpy()
    RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cuda:3 and cpu!
    

    I found self.label is on cuda device, but best_wrong_label is on cpu. https://github.com/EdisonLeeeee/GreatX/blob/73eac351fdae842dbd74967622bd0e573194c765/greatx/attack/targeted/sg_attack.py#L123-L124

    I remove line94 .cpu(), everything is going well and no error report

    I found there is a commit that adds .cpu end of line 94, so I dont know it's a bug or something else🀨

  • Add ratio for `attacker.data()`, `attacker.edge_flips()`, and `attacker.feat_flips()`

    Add ratio for `attacker.data()`, `attacker.edge_flips()`, and `attacker.feat_flips()`

    This PR allows specifying an argument ratio for attacker.edge_flips(), and attacker.feat_flips(), which determines how many generated perturbations were used for further evaluation/visualization. Correspondingly, attacker.data() holds edge_ratio and feat_ratio for these two methods when constructing perturbed graph.

    • Example
    attacker = ...
    attacker.reset()
    attacker.attack(...)
    
    # Case1: Only 50% of generated edge perturbations were used
    trainer.evaluate(attacker.data(edge_ratio=0.5), mask=...)
    
    # Case2: Only 50% of generated feature perturbations were used
    trainer.evaluate(attacker.data(feat_ratio=0.5), mask=...)
    
    # NOTE: both arguments can be used simultaneously

    GraphWar 0.1.0 πŸŽ‰

    The first major release, built upon PyTorch and PyTorch Geometric (PyG).

    About GraphWar

    GraphWar is a graph adversarial learning toolbox based on PyTorch and PyTorch Geometric (PyG). It implements a wide range of adversarial attacks and defense methods focused on graph data. To facilitate the benchmark evaluation on graphs, we also provide a set of implementations on popular Graph Neural Networks (GNNs).

    Usages

    For more details, please refer to the documentation and examples.

    How fast can we train and evaluate your own GNN?

    Take GCN as an example:

    from graphwar.nn.models import GCN
    from graphwar.training import Trainer
    from torch_geometric.datasets import Planetoid
    dataset = Planetoid(root='.', name='Cora') # Any PyG dataset is available!
    data = dataset[0]
    model = GCN(dataset.num_features, dataset.num_classes)
    trainer = Trainer(model, device='cuda:0')
    trainer.fit({'data': data, 'mask': data.train_mask})
    trainer.evaluate({'data': data, 'mask': data.test_mask})
    

    A simple targeted manipulation attack

    from graphwar.attack.targeted import RandomAttack
    attacker = RandomAttack(data)
    attacker.attack(1, num_budgets=3) # attacking target node `1` with `3` edges 
    attacked_data = attacker.data()
    edge_flips = attacker.edge_flips()
    
    

    A simple untargeted (non-targeted) manipulation attack

    from graphwar.attack.untargeted import RandomAttack
    attacker = RandomAttack(data)
    attacker.attack(num_budgets=0.05) # attacking the graph with 5% edges perturbations
    attacked_data = attacker.data()
    edge_flips = attacker.edge_flips()
    

    We will continue to develop this project and introduce more state-of-the-art implementations of papers in the field of graph adversarial attacks and defenses.
