[NeurIPS 2020] "Once-for-All Adversarial Training: In-Situ Tradeoff between Robustness and Accuracy for Free" by Haotao Wang*, Tianlong Chen*, Shupeng Gui, Ting-Kuei Hu, Ji Liu, and Zhangyang Wang - VITA-Group/Once-for-All-Adversarial-Training Several experiments have shown that feeding adversarial data into models during training increases robustness to adversarial attacks. A handful of recent works point out that those empirical de- Adversarial training is an intuitive defense method against adversarial samples, which attempts to improve the robustness of a neural network by training it with adversarial samples. Adversarial Training (AT) [3], Virtual AT [4] and Distil-lation [5] are examples of promising approaches to defend against a point-wise adversary who can alter input data-points in a separate manner. Many defense methods have been proposed to improve model robustness against adversar-ial attacks. The most common reason is to cause a malfunction in a machine learning model. Benchmarking Adversarial Robustness on Image Classiﬁcation Yinpeng Dong1, Qi-An Fu1, Xiao Yang1, ... techniques, adversarial training can generalize across dif-ferent threat models; 3) Randomization-based defenses are more robust to query-based black-box attacks. Another major stream of defenses is the certiﬁed robustness [2,3,8,12,21,35], which provides theoretical bounds of adversarial robustness. ial robustness by utilizing adversarial training or model distillation, which adds additional procedures to model training. Adversarial Training Towards Robust Multimedia Recommender System ... To date, however, there has been little effort to investigate the robustness of multimedia representation and its impact on the performance of multimedia recommendation. Unlike many existing and contemporaneous methods which make approxima-tions and optimize possibly untight bounds, we precisely integrate a perturbation-based regularizer into the classiﬁcation objective. Let’s now consider, a bit more formally, the challenge of attacking deep learning classifiers (here meaning, constructing adversarial examples them the classifier), and the challenge of training or somehow modifying existing classifiers in a manner that makes them more resistant to such attacks. Understanding adversarial robustness of DNNs has become an important issue, which would for certain result in better practical deep learning applications. Adversarial Robustness: Adversarial training improves models’ robust-ness against attacks, where the training data is augmented using adversarial sam-ples [17, 35]. (2016a), where we augment the network to run the FGSM on the training batches and compute the model’s loss function Welcome to the Adversarial Robustness Toolbox¶. In this paper, we shed light on the robustness of multimedia recommender system. adversarial training (AT) [19], model after adversarial logit pairing (ALP) [16], and model after our proposed TLA training. The result shows UM is highly non- Beside exploiting adversarial training framework, we show that by enforcing a Deep Neural Network (DNN) to be linear in transformed input and feature space improves robustness significantly. Brief review: risk, training, and testing sets . One year ago, IBM Research published the first major release of the Adversarial Robustness Toolbox (ART) v1.0, an open-source Python library for machine learning (ML) security.ART v1.0 marked a milestone in AI Security by extending unified support of adversarial ML beyond deep learning towards conventional ML models and towards a large variety of data types beyond images including tabular data. Adversarial Robustness: From Self-Supervised Pre-Training to Fine-Tuning Enhancing Intrinsic Adversarial Robustness via Feature Pyramid Decoder Single-Step Adversarial Training … Deep neural networks (DNNs) are vulnerable to adversarial examples crafted by imperceptible perturbations. While existing work in robust deep learning has focused on small pixel-level ℓp norm-based perturbations, this may not account for perturbations encountered in several real world settings. 2 The (adversarial) game is on! Adversarial Robustness Through Local Lipschitzness. Adversarial Robustness Toolbox (ART) is a Python library for Machine Learning Security. The goal of RobustBench is to systematically track the real progress in adversarial robustness. Even so, more research needs to be carried out to investigate to what extent this type of adversarial training for NLP tasks can help models generalize to real world data that hasn’t been crafted in an adversarial fashion. We follow the method implemented in Papernot et al. Adversarial training is often formulated as a min-max optimization problem, with the inner … We investigate this training procedure because we are interested in how much adversarial training can increase robustness relative to existing trained models, potentially as part of a multi-step process to improve model generalization. Adversarial Training and Robustness for Multiple Perturbations. In combination with adversarial training, later works [21, 36, 61, 55] achieve improved robustness by regularizing the feature representations with ad- 04/30/2019 ∙ by Florian Tramèr, et al. adversarial training with a PGD adversary (which incor-porates PGD-attacked examples into the training process) has so far remained empirically robust (Madry et al., 2018). Our method outperforms most sophisticated adversarial training … Adversarial Robustness Toolbox (ART) provides tools that enable developers and researchers to evaluate, defend, and verify Machine Learning models and applications against adversarial threats. Extended Support . Though all the adversarial images belong to the same true class, UM separates them into different false classes with large margins. Adversarial robustness has been initially studied solely through the lens of machine learning security, but recently a line of work studied the effect of imposing adversarial robustness as a prior on learned feature representations. Adversarial robustness and training. ADVERSARIAL TRAINING WITH PGD REQUIRES MANY FWD/BWD PASSES CVPR 19 Xie, Wu, Maaten, Yuille, He “Feature denoising for improving adversarial robustness” Impractical for ImageNet? Adversarial Training In adversarial training (Kurakin, Goodfellow, and Bengio 2016b), we increase robustness by injecting adversarial examples into the training proce-dure. A range of defense techniques have been proposed to improve DNN robustness to adversarial examples, among which adversarial training has been demonstrated to be the most effective. Join the Conversation. Using the state-of-the-art recommendation … There are already more than 2'000 papers on this topic, but it is still unclear which approaches really work and which only lead to overestimated robustness.We start from benchmarking the $$\ell_\infty$$- and $$\ell_2$$-robustness since these are the most studied settings in the literature. Improving Adversarial Robustness by Enforcing Local and Global Compactness Anh Bui 1[0000 00034123 2628], Trung Le 0414 9067], He Zhao1[0000 0003 0894 2265], Paul Montague2[0000 0001 9461 7471], Olivier deVel 2[00000001 5179 3707], Tamas Abraham 0003 2466 7646], and Dinh Phung1[0000 0002 9977 8247] 1 Monash University, Australia … However, we are also interested in and encourage future exploration of loss landscapes of models adversarially trained from scratch. Adversarial training improves the model robustness by train-ing on adversarial examples generated by FGSM and PGD (Goodfellow et al., 2015; Madry et al., 2018). Get Started. For other perturbations, these defenses offer no guarantees and, at times, even increase the model's vulnerability. In this paper, we propose a new training paradigm called Guided Complement Entropy (GCE) that iscapableofachieving“adversarialdefenseforfree,”which involves no additional procedures in the process of im- provingadversarialrobustness. This next table summarizes the adversarial performance, where adversarial robustness is with respect to the learned perturbation set. To address this issue, we try to explain adversarial robustness for deep models from a new perspective of critical attacking route, which is computed by a gradient-based influence propagation strategy. In this paper, we introduce “deep defense”, an adversarial regularization method to train DNNs with improved robustness. Adversarial training, which consists in training a model directly on adversarial examples, came out as the best defense in average. 1. May 4, 2020 • Cyrus Rashtchian and Yao-Yuan Yang. ∙ 0 ∙ share Defenses against adversarial examples, such as adversarial training, are typically tailored to a single perturbation type (e.g., small ℓ_∞-noise). . IBM moved ART to LF AI in July 2020. Defense based on ran- domization could be overcome by the Expectation Over Transformation technique proposed by [2] which consists in taking the expectation over the network to craft the perturbation. We currently implement multiple Lp-bounded attacks (L1, L2, Linf) as well as rotation-translation attacks, for both MNIST and CIFAR10. Most machine learning techniques were designed to work on specific problem sets in which the training and test data are generated from the same statistical distribution (). ART provides tools that enable developers and researchers to evaluate, defend, certify and verify Machine Learning models and applications against the adversarial threats of Evasion, Poisoning, Extraction, and Inference. which adversarial training is the most effective. Adversarial performance of data augmentation and adversarial training. Adversarial robustness. It’s our sincere hope that AdverTorch helps you in your research and that you find its components useful. We also demonstrate that by augmenting the objective function with Local Lipschitz regularizer boost robustness of the model further. Our work studies the scalability and effectiveness of adversarial training for achieving robustness against a combination of multiple types of adversarial examples. Approaches range from adding stochasticity [6], to label smoothening and feature squeezing [26, 37], to de-noising and training on adversarial examples [21, 18]. Adversarial machine learning is a machine learning technique that attempts to fool models by supplying deceptive input. adversarial training and its variants (Madry et al., 2017; Zhang et al., 2019a; Shafahi et al., 2019), various regular- izations (Cisse et al., 2017; Lin et al., 2019; Jakubovitz & Giryes, 2018), generative model based defense (Sun et al., 2019), Bayesian adversarial learning (Ye & Zhu, 2018), TRADES method (Zhang et al., 2019b), etc. Training Deep Neural Networks for Interpretability and Adversarial Robustness 15 4.6 Discussion Disentangling the effects of Jacobian norms and target interpretations. In many such cases although test data might not be available, broad specifications about the types of perturbations (such as an unknown degree of rotation) may be known. Many recent defenses [17,19,20,24,29,32,44] are designed to work with or to improve adversarial training. Neural networks are very susceptible to adversarial examples, a.k.a., small perturbations of normal inputs that cause a classifier to output the wrong label. Features. The adversarial training [14,26] is one of the few surviving approaches and has shown to work well under many conditions empirically. Since building the toolkit, we’ve already used it for two papers: i) On the Sensitivity of Adversarial Robustness to Input Data Distributions; and ii) MMA Training: Direct Input Space Margin Maximization through Adversarial Training.
