a little is enough: circumventing defenses for distributed learning
The goal of decentralized optimization over a network is to optimize a global objective formed by a sum of local (possibly nonsmooth) convex functions using only local computation and communication. Access scientific knowledge from anywhere. ... and need only be large enough. Experimental results show that the proposed algorithm converges rapidly and demonstrate its efficiency comparing to other data description algorithms. Poseidon exploits the layered model structures in DL programs to overlap communication and computation, reducing bursty network communication. In Advances in Neural Information Processing Systems (NIPS). We observe that if the empirical variance between the gradients of workers is high enough, an attacker could take advantage of this and launch a non-omniscient attack that operates within the population variance. Since MTDL leverages the knowledge among the expression data of multiple cancers to learn a more stable representation for rare cancers, it can boost cancer diagnosis performance even if their expression data are inadequate. Downpour SGD and Sandblaster L-BFGS both increase the scale and speed of deep network train-ing. Obfuscated Gradients Give a False Sense of Security: Circumventing Defenses to Adversarial Examples, Athalye et al, ICML 2018. arXiv. It is crucial not only to model cross-modal relationship effectively but also to ensure robustness against loss of part of data or modalities. A Little Is Enough: Circumventing Defenses For Distributed Learning. Mitigating sybils in federated learning poisoning. show using novel theoretical analysis, algorithms, and implementation that SGD arXiv:1602.05629. Generalized Byzantine-tolerant SGD. We show that the variance is indeed high enough even for simple datasets such as MNIST, allowing an attack that is not only undetected by existing defenses, but also uses their power against them, causing those defense mechanisms to consistently select the byzantine workers while discarding legitimate ones. Get the latest machine learning methods with code. Our goal is to design robust algorithms such that the system can learn the underlying true parameter, which is of dimension d, despite the interruption of the Byzantine attacks. problem is sparse, meaning most gradient updates only modify small parts of the Papers published at the Neural Information Processing Systems Conference. 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. We demonstrate our attack method works not only for preventing convergence but also for repurposing of the model behavior (``backdooring''). on Machine Learning (ICML), pages 3521-3530. Communication-efficient learning of deep networks from decentralized data. This framework offers two relaxations to balance system performance and algorithm efficiency. In this paper, we propose a model which can be used for multiple tasks in Person Re-Identification, provide state-of-the-art, Classification using multimodal data arises in many machine learning applications. However, current distributed DL implementations can scale poorly due to substantial parameter synchronization over the network, because the high throughput of GPUs allows more data batches to be processed per unit time than CPUs, leading to more frequent network synchronization. The experimental results show that MTDL significantly improves the performance of diagnosing every type of cancer when it learns from the aggregation of the expression data of twelve types of cancers. 02/16/2019 ∙ by Moran Baruch, et al. In Advances in Neural Information Processing Systems (NIPS). 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. Created Date: 20190219030009Z Deep learning in a collaborative setting is emerging as a corner-stone of many upcoming applications, wherein untrusted users collaborate to generate more accurate models. We present Poseidon, an efficient communication architecture for distributed DL on GPUs. We survey the intersection of AD and machine learning, cover applications where AD has direct relevance, and address the main implementation techniques. However, with the decrease of training time, the accuracy degradation has emerged.

Experiments over NORB and MNIST data sets show that the improved broad learning system achieves acceptable results. This absence of human supervision over the data collection process exposes organizations to security vulnerabilities: malicious agents can insert poisoned examples into the training set to exploit the … However, if a particular tumor has insufficient gene expressions, the trained deep neural networks may lead to a bad, We present an approach that leverages multiple datasets possibly annotated using different classes to improve the semantic segmentation accuracy on each individual dataset. This paper describes a third-generation parameter server framework for distributed machine learning. in backdoor attacks. ResearchGate has not been able to resolve any citations for this publication. of Computer Science, Bar Ilan University, Israel 2 The Allen Institute for Artiﬁcial Intelligence Abstract We show that less than 25\% of colluding workers are sufficient to degrade the accuracy of models trained on MNIST, CIFAR10 and CIFAR100 by 50\%, as well as to introduce backdoors without hurting the accuracy for MNIST and CIFAR10 datasets, but with a degradation for CIFAR100. We show how the, It is widely observed that deep learning models with learned parameters generalize well, even with much more model parameters than the number of training samples. (2018). feed-forward networks. achieves a nearly optimal rate of convergence. Indirect collaborative deep learning is preferred over direct, because it distributes the cost of computation and can be made privacy-preserving. Federated learning: Strategies for improving communication efficiency. Won best paper at ICML. 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. (ICLR) Workshop. An implementation for the paper "A Little Is Enough: Circumventing Defenses For Distributed Learning" (NeurIPS 2019) - moranant/attacking_distributed_learning A distributed denial of service (DDoS) attack is a malicious attempt to make an online service unavailable to users, usually by temporarily interrupting or suspending the services of its hosting server. We demonstrate our attack method works not only for preventing convergence but also for repurposing of the model behavior (backdooring). Processing Systems 31 (NIPS). Join ResearchGate to find the people and research you need to help your work. models, deals with cross-modal information carefully, and prevents performance degradation due to partial absence of data. Auror provides a strong guarantee against evasion; if the attacker tries to evade, its attack effectiveness is bounded. To address this problem, we introduce an elastic-net-type constrain on the kernel weights. International Conference on Learning Representations Workshop ∙ 6 ∙ share 投稿日:2020年1月22日 20時29分 Yuji Tokuda 量子化どこまでできる？ 投稿者:Yuji Tokuda. Our analysis clearly separates the convergence of the optimization algorithm itself from the effects of communication constraints arising from the network structure. As a defense, we propose Auror, a system that detects malicious users and generates an accurate model. 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. 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. Speaker Deck. Distributed learning is central for large-scale training of deep-learning models. We have developed a software framework called DistBelief that can utilize computing clusters with thousands of machines to train large models. arXiv preprint This week’s topic covered some proposed adversarial example attacks and defenses. It combines the power of deep learning and matte propagation and can therefore surpass prior state-of-the-art matting techniques in terms of both accuracy and training complexity, as validated by our experimental results from 243K images created based on two benchmark matting databases. that use locking by an order of magnitude.
