"Concurrent Treatment of Parametric Uncertainty and Metamodeling Uncertainty in Robust Design,", Orlando ,
In the fields of science and engineering, the accuracy of a measurement system is the degree of closeness of measurements of a quantity to that quantity's true value. 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.) 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. Robustness in this sense re ects the system’s ability to perform multiple functionalities as needed without change in structure|this might be called \phenotypical plasticity." "The Use of Ranks to Avoid the Assumption of Normality Implicit in the Analysis of Variance,", Hwang, C. L., A. S. M. Masud. Pages 616–627. It is concluded that the bi-criteria optimized ensembles render not only accurate but also robust metamodels. We take a closer look at this phenomenon and first show that real image datasets are actually separated. A metamodel is a surrogate model used to approximate a computationally expensive simulation model. "An Efficient Pareto Set Identification Approach for Multiobjective Optimization on Black-Box Functions. Build in robustness so that DR s is small when separation variables are changed. A metamodel is a surrogate model used to approximate a computationally expensive simulation model. Simulation has been widely used in modeling engineering systems. Accuracy and robustness are like two rabbits, who are running the opposite directions. %PDF-1.3 Chang, C., C. Lin. The construction does not assume knowledge of f and can scale to large networks.
