We address the issue of efficiency in quality and reliability assurance for complex dynamical systems using active learning. The problem can be regarded as contour, also called iso-surface, estimation. In some cases, obtaining the true iso-surface according to the traditional one-shot design is inefficient because computer simulations can be cumbersome. Hence, we propose the method that combines a cheap surrogate model (low-fidelity model) and high-fidelity computer simulations to efficiently approximate the contour of interest. The paradigm is called active learning. The core idea is that not all the data result in the significant surrogate model update and we design the strategies to find "useful" data to speed up the convergence of surrogate models with the least number of training data. Consequently, the number of expensive high-fidelity computer simulations are significantly reduced.
