Improving Adversarial Robustness of Ensembles with Diversity Training

  title={Improving Adversarial Robustness of Ensembles with Diversity Training},
  author={Sanjay Kariyappa and Moinuddin K. Qureshi},
Deep Neural Networks are vulnerable to adversarial attacks even in settings where the attacker has no direct access to the model being attacked. Such attacks usually rely on the principle of transferability, whereby an attack crafted on a surrogate model tends to transfer to the target model. We show that an ensemble of models with misaligned loss gradients can provide an effective defense against transfer-based attacks. Our key insight is that an adversarial example is less likely to fool…

Evaluating Ensemble Robustness Against Adversarial Attacks

This paper introduces a gradient based measure of how effectively an ensemble's constituent models collaborate to reduce the space of adversarial examples targeting the ensemble itself and demonstrates that this measure can be utilized during training as to increase an ensemble’s robustness to adversarialExamples.

PARL: Enhancing Diversity of Ensemble Networks to Resist Adversarial Attacks via Pairwise Adversarially Robust Loss Function

This paper attempts to develop a new ensemble methodology that constructs multiple diverse classifiers using a Pairwise Adversarially Robust Loss (PARL) function during the training procedure and evaluates the robustness in the presence of white-box attacks.

Improving Ensemble Robustness by Collaboratively Promoting and Demoting Adversarial Robustness

This work proposes a simple, but effective strategy to collaborate among committee models of an ensemble model via the secure and insecure sets defined for each model member on a given sample, which provides the flexibility to reduce the adversarial transferability and promote the diversity of ensemble members, which are two crucial factors for better robustness in this ensemble approach.

Resisting Adversarial Attacks in Deep Neural Networks using Diverse Decision Boundaries

This paper attempts to develop a new ensemble-based solution that constructs defender models with diverse decision boundaries with respect to the original model, and presents extensive experimentations using standard image classification datasets against state-of-the-art adversarial attacks to demonstrate the robustness of the proposed ensemble- based defense.

Ensemble Defense with Data Diversity: Weak Correlation Implies Strong Robustness

The framework builds an ensemble of sub-models — DNNs with differentiated preprocessing filters that are more robust than those constructed by previous defense methods like adversarial training, and even competitive with the classical ensemble of adversarial trained Dnns under adversarial attacks when the attacking radius is large.

DVERGE: Diversifying Vulnerabilities for Enhanced Robust Generation of Ensembles

DVERGE is proposed, which isolates the adversarial vulnerability in each sub-model by distilling non-robust features, and diversifies the adversarian vulnerability to induce diverse outputs against a transfer attack, and enables the improved robustness when more sub-models are added to the ensemble.

Defending Adversarial Examples by Negative Correlation Ensemble

A new ensemble defense approach named the Negative Correlation Ensemble (NCEn), which achieves compelling results by introducing gradient directions and gradient magnitudes of each member in the ensemble negatively correlated and at the same time, reducing the transferability of adversarial examples among them.

MORA is introduced, a model-reweighing attack to steer adversarial example synthesis by reweighed the importance of sub-model gradients, finding that recent ensemble defenses all exhibit varying degrees of overestimated robustness.

Adversarial Vulnerability of Randomized Ensembles

This work proposes a theoretically-sound and efficient adversarial attack algorithm (ARC) capable of compromising random ensembles even in cases where adaptive PGD fails to do so, and empirically establishes that randomizedEnsembles are in fact more vulnerable to ℓ p -bounded adversarial perturbations than even standard AT models.

A strong attack algorithm named momentum iterative fast gradient sign method (MI-FGSM) is proposed to discover adversarial examples and can serve as a benchmark attack algorithm for evaluating the robustness of various models and defense methods.

Ensemble Adversarial Training: Attacks and Defenses

This work finds that adversarial training remains vulnerable to black-box attacks, where perturbations computed on undefended models are transferred to a powerful novel single-step attack that escapes the non-smooth vicinity of the input data via a small random step.

Stochastic Activation Pruning (SAP) is proposed, a mixed strategy for adversarial defense that prunes a random subset of activations (preferentially pruning those with smaller magnitude) and scales up the survivors to compensate.

This research applies adversarial training to ImageNet and finds that single-step attacks are the best for mounting black-box attacks, and resolution of a "label leaking" effect that causes adversarially trained models to perform better on adversarial examples than on clean examples.

Mitigating adversarial effects through randomization

This paper proposes to utilize randomization at inference time to mitigate adversarial effects, and uses two randomization operations: random resizing, which resizes the input images to a random size, and random padding, which pads zeros around the input image in a random manner.

Experimental results show that cascade adversarial training together with the proposed low-level similarity learning efficiently enhances the robustness against iterative attacks, but at the expense of decreased robustnessagainst one-step attacks.
