The prediction accuracy has been the long-lasting and sole standard for comparing the performance of different image classification models, including the ImageNet competition. Accuracy A test method is said to be accurate when it measures what it is supposed to measure. The terms robustness and ruggedness refer to the ability of an analytical method to remain unaffected by small variations in the method parameters (mobile phase composition, column age, column temperature, etc.) 1979. Variable conditions might include different machines, operators, and reagent lots. We take a closer look at this phenomenon and first show that real image datasets are actually separated. ", Clarke, S. M., J. H. Griebsch, T. W. Simpson. 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.

The higher this worst-case prediction accuracy of a model is, the more spatially robust we say it is. 3) Robust Physical-World Attack Inspired by our theoretical analysis, we also design a new defense method, TRADES, to trade adversarial robustness off against accuracy. Seven geometrical and statistical metrics are introduced to explore the relationships between the function properties and the ensemble models. Our proposed algorithm performs well experimentally in real-world datasets. Accuracy and robustness are like two rabbits, who are running the opposite directions. This means it is able to measure the true amount or concentration of a substance in a sample. Banks, J., J. S. Carson, B. L. Nelson, and D. M. Nicol. 1 $\begingroup$ Firstly, it is important to decide what is the loss function you want to use in your evaluation. The method focuses on restricted robustness-like properties, and requires sampling at inference time, not required by convex methods. The prediction accuracy has been the long-lasting and sole standard for comparing the performance of different image classification models, including the ImageNet competition. A robustness check means that your results are not highly determined by changes to your dataset (i.e. 2011. Simulation has been widely used in modeling engineering systems. 2005. Reliability and Robustness are two very different things. 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%. Accuracy: Accuracy of a measurement means getting a value that is close to the actual answer.
