Person re-identification (re-ID) requires one to match images of the same person across camera views. generalization_simplicity_robust_nets_paper.pdf. that adversarial generalization may require more data than natural generalization [38]. Adversarial training has been the topic of dozens of studies and a leading method for defending against adversarial attacks. Adversarial Robustness May Be at Odds With Simplicity. In this work, we study whether more labeled data is necessary, or whether unlabeled data … green. As a more challenging task, semi-supervised re-ID tackles the problem that only a number of identities in training data are fully labeled, while the remaining are unlabeled. 01/02/2019 ∙ by Preetum Nakkiran, et al. that in natural settings, if robust classification is feasible, robust classifiers could be found with a sample complexity that is only polynomially larger than that of normal learning. Manifold regularization is a technique that penalizes the complexity of learned functions over the intrinsic geometry of input data. ). that robust learning might require more data, but it was also shown by Attias et al. color, edge, and. The idea of RPCA may be used into AEs to train more robust ... characteristics of unlabeled data, that helps ... to represent data. Posits that unlabeled data can be a competitive alternative to labelled data for training adversarially robust models. ... suggests that R models would require more neurons to mimic a complex standard. ... AlexNet-R comprises of more just. The result is clear: When we estimate a Naive Bayes classifier with data generated from a Naive Bayes model, more unlabeled data help; when we estimate a Naive Bayes classifier with data that do not come from a corresponding model, more unlabeled data can degrade performance (even for the case of 30 labeled and 30,000 unlabeled samples! 2.3. In this work, we study whether more labeled data is necessary, or whether unlabeled data … Yet, it remains largely unknown (a) how adversarially-robust ImageNet classifiers (R classifiers) generalize to out-of-distribution examples; and (b) how their generalization capability relates to their hidden representations. One solution explored in [17] is to use pretraining on ImageNet, a large supervised dataset, to improve adversarial robustness. In particular, it is proved by Attias et al. ∙ Harvard University ∙ 0 ∙ share . We develop a connection to learning functions which are "locally stable", and propose new regularization terms for training deep neural networks that are stable against a class of local perturbations. Current techniques in machine learning are so far are unable to learn classifiers that are robust to adversarial perturbations. that adversarial generalization may require more data than natural generalization [34]. generative models are generally known to require more data to train than a classification model, and for training, addi-tional synthetic [32, 35, 43] and/or unlabeled [24, 26, 25] samples are required. By design, data lakes give the end user more flexibility (or elasticity in terms of data provisioning) and probably even more insight because of the availability of raw data. Inuence functions The influence function is a function from robust statis-tics [5] to estimate how model parameters change due to The downside, however, is that data lakes tend to create additional complexity, cost, and latency, which only get worsened as data volume increases. ; Bubeck et al. One solution explored in [19] is to use pretraining on ImageNet, a large supervised dataset, to improve adversarial robustness. Theoretically, shows that in a simple statistical setting, the sample complexity for learning an adversarially robust model from unlabeled data matches the fully supervised case.
