Usage

Image Attack and Defense

1. Train model

   Example: Train a simple CNN model on MNIST dataset for 20 epoch on gpu.

   import deeprobust.image.netmodels.train_model as trainmodel
   trainmodel.train('CNN', 'MNIST', 'cuda', 20)

   Model would be saved in deeprobust/trained_models/.

2. Instantiated attack methods and defense methods.

   Example: Generate adversary example with PGD attack.

   from deeprobust.image.attack.pgd import PGD
   from deeprobust.image.config import attack_params
   from deeprobust.image.utils import download_model
   import torch
   import deeprobust.image.netmodels.resnet as resnet
   from torchvision import transforms,datasets
   
   URL = "https://github.com/I-am-Bot/deeprobust_model/raw/master/CIFAR10_ResNet18_epoch_20.pt"
   download_model(URL, "$MODEL_PATH$")
   
   model = resnet.ResNet18().to('cuda')
   model.load_state_dict(torch.load("$MODEL_PATH$"))
   model.eval()
   
   transform_val = transforms.Compose([transforms.ToTensor()])
   test_loader  = torch.utils.data.DataLoader(
                   datasets.CIFAR10('deeprobust/image/data', train = False, download=True,
                   transform = transform_val),
                   batch_size = 10, shuffle=True)
   
   x, y = next(iter(test_loader))
   x = x.to('cuda').float()
   
   adversary = PGD(model, 'cuda')
   Adv_img = adversary.generate(x, y, **attack_params['PGD_CIFAR10'])

   Example: Train defense model.

   from deeprobust.image.defense.pgdtraining import PGDtraining
   from deeprobust.image.config import defense_params
   from deeprobust.image.netmodels.CNN import Net
   import torch
   from torchvision import datasets, transforms 
   
   model = Net()
   train_loader = torch.utils.data.DataLoader(
                   datasets.MNIST('deeprobust/image/defense/data', train=True, download=True,
                                   transform=transforms.Compose([transforms.ToTensor()])),
                                   batch_size=100,shuffle=True)
   
   test_loader = torch.utils.data.DataLoader(
                 datasets.MNIST('deeprobust/image/defense/data', train=False,
                               transform=transforms.Compose([transforms.ToTensor()])),
                               batch_size=1000,shuffle=True)
   
   defense = PGDtraining(model, 'cuda')
   defense.generate(train_loader, test_loader, **defense_params["PGDtraining_MNIST"])

   More example code can be found in deeprobust/examples.

3. Use our evulation program to test attack algorithm against defense.

   Example:

   cd DeepRobust
   python examples/image/test_train.py
   python deeprobust/image/evaluation_attack.py
   

Graph Attack and Defense

Attacking Graph Neural Networks

1. Load dataset

   import torch
   import numpy as np
   from deeprobust.graph.data import Dataset
   from deeprobust.graph.defense import GCN
   from deeprobust.graph.global_attack import Metattack
   
   data = Dataset(root='/tmp/', name='cora', setting='nettack')
   adj, features, labels = data.adj, data.features, data.labels
   idx_train, idx_val, idx_test = data.idx_train, data.idx_val, data.idx_test
   idx_unlabeled = np.union1d(idx_val, idx_test)

2. Set up surrogate model

   device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")
   surrogate = GCN(nfeat=features.shape[1], nclass=labels.max().item()+1, nhid=16,
                   with_relu=False, device=device)
   surrogate = surrogate.to(device)
   surrogate.fit(features, adj, labels, idx_train)

3. Set up attack model and generate perturbations

   model = Metattack(model=surrogate, nnodes=adj.shape[0], feature_shape=features.shape, device=device)
   model = model.to(device)
   perturbations = int(0.05 * (adj.sum() // 2))
   model.attack(features, adj, labels, idx_train, idx_unlabeled, perturbations, ll_constraint=False)
   modified_adj = model.modified_adj

For more details please refer to mettack.py or run python examples/graph/test_mettack.py --dataset cora --ptb_rate 0.05

Defending Against Graph Attacks

1. Load dataset

   import torch
   from deeprobust.graph.data import Dataset, PtbDataset
   from deeprobust.graph.defense import GCN, GCNJaccard
   import numpy as np
   np.random.seed(15)
   
   # load clean graph
   data = Dataset(root='/tmp/', name='cora', setting='nettack')
   adj, features, labels = data.adj, data.features, data.labels
   idx_train, idx_val, idx_test = data.idx_train, data.idx_val, data.idx_test
   
   # load pre-attacked graph by mettack
   perturbed_data = PtbDataset(root='/tmp/', name='cora')
   perturbed_adj = perturbed_data.adj

2. Test

   # Set up defense model and test performance
   device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")
   model = GCNJaccard(nfeat=features.shape[1], nclass=labels.max()+1, nhid=16, device=device)
   model = model.to(device)
   model.fit(features, perturbed_adj, labels, idx_train)
   model.eval()
   output = model.test(idx_test)
   
   # Test on GCN
   model = GCN(nfeat=features.shape[1], nclass=labels.max()+1, nhid=16, device=device)
   model = model.to(device)
   model.fit(features, perturbed_adj, labels, idx_train)
   model.eval()
   output = model.test(idx_test)

For more details please refer to test_gcn_jaccard.py or run python examples/graph/test_gcn_jaccard.py --dataset cora
