I believe it would best be understood with an example. Robust CIFAR10 classifier [2]: 99% train accuracy and 87% test accuracy; 96% adversarial train accuracy and 47% adversarial test accuracy Attack strategy: infer an input as a member if its prediction confidence is larger than a preset threshold, a non-member otherwise Attack results: 57.43% membership inference accuracy … Therefore, the required large network capacity by adver- However, in practice it is useful to consider that accuracy is quantitatively expressed as a measurement uncertainty. A number of robustness metrics have been used to measure system performance under deep uncertainty, such as: Expected value metrics (Wald, 1950), which indicate an expected level of performance across a range of scenarios. "Krigeage d'un Panneau Rectangulaire Par sa Périphérie,", Nemenyi, P. B. The heavy solid line corresponds to the baseline model with robustness and mistuning set to zero (see Fig. We see a clear trade-off between robustness and accuracy. In addition, increasing the network capacity may provide a better trade-off between standard accuracy of an adversarially trained model and its adversarial robustness [41]. 3.3 Robustness and accuracy of shape-based representations. If it's correct, then it gets a 1, if incorrect then 0. so predictions using observations(1 - N-1) to predict observation N. So if a model had a string of predictions like so: 1,1,0,1,1,1,1,0,0,0 then the accuracy is .6 or 60%. ∙ 3 ∙ share . Engineering with Computers 17(2): 129--150. Accuracy: Accuracy of a measurement means getting a value that is close to the actual answer. Is Robustness the Cost of Accuracy?

Inspired by our theoretical analysis, we also design a new defense method, TRADES, to trade adversarial robustness off against accuracy. Robustness is a test's resistance to score inflation through whatever cause; practice effects, fraud, answer leakage, increasing quality of research materials like the Internet, unauthorized publication and so on. Metrics of higher‐order moments, such as variance and skew (e.g., Kwakkel et al., 2016b), which provide information on how the expected level of performance … Robustness vs. classiﬁcation accuracy plots of I-FGSM attack [37], C&W at- tack [39] and CLEVER [15] score on random targets over 18 ImageNet models.

To do so, we applied different dimensionality reduction methods to each of 30 scRNA-seq data sets (28 real data and 2 simulated data; excluding the two large-scale data due to computing concerns) and evaluated the performance of these dimensionality reduction methods based on neighborhood preserving. We see the same pattern between standard and robust accuracies for other values of !. 2013. ", Li, Y. F., S. H. Ng, M. Xie, and T. N. Goh. Assume that you have a product called "The Super Cake". Accuracy is not precision! The precision of a measurement system, related to reproducibility and repeatability, is the degree to which repeated measurements under unchanged conditions show the same results. Accurate, reliable and fast robustness evaluation. Ruggedness provides an estimate of experimental reproducibility with unavoidable error.

ABSTRACT. and influential environmental factors (room temperature, air humidity, etc.) A Closer Look at Accuracy vs. Robustness. For example, If you are building a model for a financial client like a credit card fraud detection your model should be as accurate and robust as possible. In addition to the IN- and SIN-trained ResNet-50 architecture we here additionally analyse two joint training schemes: Perhaps even more remarkable than the accuracy of division in rod-shape cells is the robustness of cell division that occurs in aberrant forms of bacteria. Robustness vs. "Metamodels for Computer-based Engineering Design: Survey and Recommendations." ISSN 1751-8784 Robustness The robustness of an analytical procedure is a measure of its capacity to remain unaffected by small, but deliberate, variations in method parameters and provides an indication of its reliability during normal usage. ", Zhang, S., P. Zhu, W. Chen, and P. Arendt. 1979. It is the ability of a method to remain unaffected when slight variations are applied. 2010. Depends on the type of the project, I would prefer to build a model first and then tune the model depending on the requirement.

We give a theoretical justification for the invariance vs. robustness trade-off observed in our experiments (see Theorem 1) by building upon the ideas in previous work on accuracy vs robustness trade-off [15, 14]. However, recent studies have highlighted the lack of robustness in well-trained deep neural networks to adversarial examples. 1986. 2011. Accuracy A test method is said to be accurate when it measures what it is supposed to measure. Initial resolution can decrease due to changes in separation variables. A robustness check means that your results are not highly determined by changes to your dataset (i.e. The prediction accuracy has been the long-lasting and sole standard for comparing the performance of different image classification models, including the ImageNet competition. 5 Mar 2020 • Yao-Yuan Yang • Cyrus Rashtchian • Hongyang Zhang • Ruslan Salakhutdinov • Kamalika Chaudhuri.

"Numerical Procedures for Surface Fitting of Scattered Data by Radial Basis Functions. 1995. You are about to send your dog (code) to chase them. In statistics, the term robust or robustness refers to the strength of a statistical model, tests, and procedures according to the specific conditions of the statistical analysis a study hopes to achieve.Given that these conditions of a study are met, the models can be verified to be true through the use of mathematical proofs. For the evaluation of acceptability of measurement accuracy, different evaluation criteria can be used: E n-numbers, z-scores or zeta-scores. To further validate our robustness analysis, we conducted another experiment by taking the subset of images (327 images in total) that are correctly classified by all of 18 examined ImageNet models and show their accuracy-vs-robustness figures on C&W and I-FGSM targeted attacks in Figure 6.

In terms of transferability of adversarial examples, we conduct thorough experiments on each pair of the 18 ImageNet networks (306 pairs in total), which is the largest scale to date. Current methods for training robust networks lead to a drop in test accuracy, which has led prior works to posit that a robustness-accuracy tradeoff may be inevitable in deep learning. 1996. The lighter solid line corresponds to the mistuned model with σ β = 0.1. Note that, precision is a separate aspect which is not directly related to accuracy. Accuracy and robustness are like two rabbits, who are running the opposite directions. of robustness is equally valid; namely, robustness may be seen as measuring the e ectiveness of a system’s ability to switch among multiple strategic options. "A Comparative Study of Metamodeling Methods for Multiobjective Crashworthiness Optimization. A robust measurement is one that is both sensitive and precise. A metamodel is a surrogate model used to approximate a computationally expensive simulation model. Simulation has been widely used in modeling engineering systems.

Motivated by this finding, this research proposes a bi-criteria (accuracy and robustness) optimized ensemble framework to optimally identify the contributions from each metamodel (Kriging, Support Vector Regression and Radial Basis Function), where uncertainties are modeled for evaluating robustness.
