a little is enough: circumventing defenses for distributed learning

We show that when the associated optimization We show that our model outperforms state-of-the-art approaches for various text-to-SQL datasets in two aspects: 1) the SQL generation accuracy for the trained templates, and 2) the adaptability to the unseen SQL templates based on a single example without any additional training. Get the latest machine learning methods with code. Nowadays, gene expression data has been widely used to train an effective deep neural network for precise cancer diagnosis. In Advances in Neural Information It finds the best trade-off between sparsity and accuracy. arXiv preprint arXiv:1802.00420, 2018. These three modules are all differentiable and can be optimized jointly via an end-to-end. We propose a new algorithm that takes advantage of this framework to solve non-convex non-smooth problems with convergence guarantees. : A Lock-Free Approach to Parallelizing Stochastic Gradient We further provide an application of our general results to the linear regression problem. Our bound comes paired with a candidate attack that nearly realizes the bound, giving us a powerful tool for quickly assessing defenses on a given dataset. In this paper, we propose a template-based one-shot learning model for the text-to-SQL generation so that the model can generate SQL of an untrained template based on a single example. (SVM). In this paper, we study the susceptibility of collaborative deep learning systems to adversarial poisoning attacks. Most Multiple kernel learning algorithms employ the 1-norm constraints on the, Person Re-Identification is still a challenging task in Computer Vision due to variety of reasons. A little bit about me, I was an academic for, well over a decade. Abstract: Distributed learning is central for large-scale training of deep-learning models. Konečnỳ, J., McMahan, H. B., Yu, F. X., Richtárik, P., arXiv preprint A Little is Enough: Circumventing Defenses For Distributed Learning 投稿者:ShuntaroOHNO. In this paper, we consider the problem of training a deep network with billions of parameters using tens of thousands of CPU cores. More specifically, SGD will not get stuck at "sharp" local minima with small diameters, as long as the neighborhoods of these regions contain enough gradient information. of Computer Science, Bar Ilan University, Israel 2 The Allen Institute for Artificial Intelligence Abstract attack uses a gradient ascent strategy in which the gradient is computed based (2018). performance-destroying memory locking and synchronization. Federated learning: Strategies for improving communication efficiency. Abstract. Strategies for improving communication efficiency. Created Date: 20190219030009Z Empirically, we observe that the loss surface of neural networks enjoys nice one point convexity properties locally, therefore our theorem helps explain why SGD works so well for neural networks. A Little Is Enough: Circumventing Defenses For Distributed Learning. (2017). (2016). A Little is Enough: Circumventing Defenses For Distributed Learning Shuntaro Ohno January 22, 2020 Technology 0 13. In this paper, based on the geometric median of means of the gradients, we propose a simple variant of the classical gradient descent method. Accordingly, most defense mechanisms make a similar assumption and attempt to use statistically robust methods to identify and discard values whose reported gradients are far from the population mean. We demonstrate the benefits of such an approach with experiments on MNIST, fashion-MNIST, CIFAR-10 and CIFAR-100 where the proposed method is shown to greatly decrease the degradation effect and is often competitive with ResNets. We show that these same techniques dramatically accelerate the training of a more modestly-sized deep network for a commercial speech recognition ser-vice. deep networks from decentralized data.

Shirish Keskar, N., Mudigere, D., Nocedal, J., Smelyanskiy, We evaluated our model on three datasets Market 1501, CUHK-03, Duke MTMC. Detecting backdoor attacks on deep neural networks by (2018). .. A DDoS attack is launched from numerous compromised devices, often distributed … How to backdoor federated learning. In Advances in Neural Information Processing Systems (NIPS). We survey the intersection of AD and machine learning, cover applications where AD has direct relevance, and address the main implementation techniques. Federated learning: © 2008-2021 ResearchGate GmbH. Formally, we focus on a decentralized system that consists of a parameter server and m working machines; each working machine keeps N/m data samples, where N is the total number of samples. As many of you may know, Deep Neural Networks are highly expressive machine learning networks that have been around for many decades. To handle this issue in the analysis, we prove that the aggregated gradient, as a function of model parameter, converges uniformly to the true gradient function. We demonstrate experimentally that HOGWILD! kernel combination weights, which enforce a sparsity solution but maybe lose useful information. This paper describes a third-generation parameter server framework for distributed machine learning. IOP Conference Series Materials Science and Engineering. A Little Is Enough: Circumventing Defenses For Distributed Learning. malicious input and use this ability to construct malicious data. We employ two datasets for multimodal classification tasks, build models based on our architecture and other state-of-the-art models, and analyze their performance on various situations. In this paper, we propose a novel deep learning-based multimodal fusion architecture for classification tasks, which guarantees compatibility with any kind of learning, Classical linear/shallow learning is relatively easy to analyze and understand, but the power of deep learning is often desirable. Experimental results show that the proposed algorithm converges rapidly and demonstrate its efficiency comparing to other data description algorithms. On large-batch training for However, they are exposed to a security threat in which Byzantine participants can interrupt or control the learning process. (2016). A Little Is Enough: Circumventing Defenses For Distributed Learning Distributed learning is central for large-scale training of deep-learning models. Talk about the security of distributed learning. can, to some extent, predict the change of the SVM's decision function due to We develop and analyze distributed algorithms based on dual averaging of subgradients, and provide sharp bounds on their convergence rates as a function of the network size and topology. Stochastic Gradient Descent (SGD) is a popular algorithm that can achieve (2018). We investigate a family of poisoning attacks against Support Vector Machines arXiv:1602.05629. We have developed a software framework called DistBelief that can utilize computing clusters with thousands of machines to train large models. A Little Is Enough: Circumventing Defenses For Distributed Learning The paper provides a new strong attack against robust byzantine ML training algorithms. arXiv preprint We show that Poseidon enables Caffe and TensorFlow to achieve 15.5x speed-up on 16 single-GPU machines, even with limited bandwidth (10GbE) and the challenging VGG19-22K network for image classification. While recent work has proposed a number of attacks and defenses, little is understood about the worst-case loss of a defense in the face of a determined attacker. 摘要: 分布式学习面临安全威胁:拜占庭式的参与者可以中断或者控制学习过程。 以前的攻击模型和相应的防御假设流氓参与者: (a)无所不知(知道所有其他参与者的数据) Within this framework, we have developed two algorithms for large-scale distributed training: (i) Downpour SGD, an asynchronous stochastic gradient descent procedure supporting a large number of model replicas, and (ii) Sandblaster, a framework that supports a variety of distributed batch optimization procedures, including a distributed implementation of L-BFGS. In view of the limitation of random generation of connection, Most deep learning approaches for text-to-SQL generation are limited to the WikiSQL dataset, which only supports very simple queries. •Only exponentially few Byzantine gradients survive majority filtering Although we focus on and report performance of these methods as applied to training large neural networks, the underlying algorithms are applicable to any gradient-based machine learning algorithm. Generalized Byzantine-tolerant SGD. Qiao, M. and Valiant, G. (2017). enables the attack to be constructed in the input space even for non-linear However, they are exposed to a security threat in which Byzantine participants can interrupt or control the learning process. El Mhamdi, E. M., Guerraoui, R., and Rouault, S. (2018). As machine learning is applied to an increasing variety of complex problems, which are defined by high dimensional and complex data sets, the necessity for task oriented feature learning grows in importance. The market demand for online machine-learning services is increasing, and so have the threats against them. We investigate the setting of indirect collaborative deep learning --- a form of practical deep learning wherein users submit masked features rather than direct data. problem is sparse, meaning most gradient updates only modify small parts of the Previous attack models and their corresponding defenses assume that the rogue participants are (a) omniscient (know the data of all other participants), and (b) introduce large change to the parameters. In this paper, we propose a novel data domain description algorithm which is inspired by multiple kernel learning and elastic-net-type constrain on the kernel weight. cancer diagnosis performance. Meta-Gradient Reinforcement Learning, Xu et al 2018, arXiv; 2018-07. Machine learning with adversaries: Byzantine tolerant gradient descent.

SVM's test error. surface, which significantly increases the classifier's test error. In this paper, we present a novel way of learning discriminative features by, Novelty detection from multiple information sources is an important problem and selecting appropriate features is a crucial step for solving this problem. On the other side, Incremental Learning is still an issue since Deep Learning models tend to face the problem of overcatastrophic forgetting when trained on subsequent tasks. JP - Baruch et al.
