Auror provides a strong guarantee against evasion; if the attacker tries to evade, its attack effectiveness is bounded. (2017). This work aims to Chen, B., Carvalho, W., Baracaldo, N., Ludwig, H., Edwards, B., Lee, T., Molloy, I., and Srivastava, B. On large-batch training for As a defense, we propose Auror, a system that detects malicious users and generates an accurate model. In order to understand this phenomenon, we take an alternative view that SGD is working on the convolved (thus smoothed) version of the loss function. This allows for skip-connections to be introduced during the early stages of training and subsequently phased out in a principled manner. Experimental results show that the proposed algorithm converges rapidly and demonstrate its efficiency comparing to other data description algorithms. The accuracy under the deployed defense on practical datasets is nearly unchanged when operating in the absence of attacks. Strategies for improving communication efficiency. The sharpness of this prediction is confirmed both by theoretical lower bounds and simulations for various networks. arXiv preprint (2018).

Detecting backdoor attacks on deep neural networks by We show that small but well-crafted changes are sufficient, leading to a novel non-omniscient attack on distributed learning that go undetected by all existing defenses. Distributed learning is central for large-scale training of deep-learning models. distributions from untrusted batches. of overwriting each other's work. This attack seems to be effective across a wide range of settings, and hence is a useful contribution to the related byzantine ML literature. 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. 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. Extensive experiments show that this method can achieve Incremental Learning in Person ReID efficiently as well as for other tasks in computer vision as well.

However, the degradation problem persists in the context of plain, Using computational techniques especially deep learning methods to facilitate and enhance cancer detection and diagnosis is a promising and important area. A Little Is Enough: Circumventing Defenses For Distributed Learning. Downpour SGD and Sandblaster L-BFGS both increase the scale and speed of deep network train-ing. reliably identifies good local maxima of the non-convex validation error that use locking by an order of magnitude. Central to the motivation for these attacks is the fact that For the landscape of loss function for deep networks, the volume of basin of attraction of good minima dominates over that of poor minima, which guarantees optimization methods with random initialization to converge to good minima. We propose a new algorithm that takes advantage of this framework to solve non-convex non-smooth problems with convergence guarantees. 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. My research has mostly focused on learning from corrupted or inconsistent training data (`agnostic learning'). on properties of the SVM's optimal solution. Moreover, Poseidon-enabled TensorFlow achieves 31.5x speed-up with 32 single-GPU machines on Inception-V3, a 50% improvement over the open-source TensorFlow (20x speed-up).

I am developing a hybrid approach in order to obtain learning algorithms that are both trustworthy and accurate. Browse our catalogue of tasks and access state-of-the-art solutions. Poseidon exploits the layered model structures in DL programs to overlap communication and computation, reducing bursty network communication. 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. researchers have recently proposed schemes to parallelize SGD, but all require arXiv preprint To address this problem, we introduce an elastic-net-type constrain on the kernel weights. Obfuscated Gradients Give a False Sense of Security: Circumventing Defenses to Adversarial Examples, Athalye et al, ICML 2018. arXiv. kernel combination weights, which enforce a sparsity solution but maybe lose useful information. 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. For deeper networks, extensive numerical evidence helps to support our arguments. activation clustering. Xie, C., Koyejo, O., and Gupta, I. Blanchard, P., Guerraoui, R., Stainer, J., et al. This paper describes a third-generation parameter server framework for distributed machine learning. We show that it, In this paper, we propose a deep propagation based image matting framework by introducing deep learning into learning an alpha matte propagation principal. 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. In contrast, imposing the p-norm(p>1) constraint on the kernel weights will keep all the information in the base kernels, which lead to non-sparse solutions and brings the risk of being sensitive to noise and incorporating redundant information. We have developed a software framework called DistBelief that can utilize computing clusters with thousands of machines to train large models. Stochastic Gradient Descent (SGD) is a popular algorithm that can achieve (2018). We have successfully used our system to train a deep network 30x larger than previously reported in the literature, and achieves state-of-the-art performance on ImageNet, a visual object recognition task with 16 million images and 21k cate-gories. Our result identifies a set of functions that SGD provably works, which is much larger than the set of convex functions. The goal of a basketball game is pretty simple: get more balls into the basket than the other team. A Little is Enough: Circumventing Defenses For Distributed Learning Shuntaro Ohno January 22, 2020 Technology 0 13. 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. Abstract. on Machine Learning (ICML), pages 3521-3530. Recently, I, as well as independent, Although breakthrough achievements of deep learning have been made in different areas, there is no good idea to prevent the time-consuming training process. 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. IOP Conference Series Materials Science and Engineering. Implemented in 3 code libraries. Abstract: Distributed learning is central for large-scale training of deep-learning models. The proposed algorithm can be equivalently formalized as a convex-concave problem that can be effectively resolved with level method. noise improves learning for very deep networks.

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. feed-forward networks. We demonstrate our attack method works not only for preventing convergence but also for repurposing of the model behavior (``backdooring''). 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. BLS) are used to reduce the training time. Until very recently, the fields of machine learning and AD have largely been unaware of each other and, in some cases, have independently discovered each other’s results. Theorem 1:Majority voting needs only logarithmic redundancy to reduce the effective number Byzantine workers to a constant. 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.
