| Abstract(in English) | Level set estimation is a problem to identify a level set of an unknown function, which is defined by whether the function values are larger or smaller than a certain threshold. In practice, low cost approximate functions to the true function are often available. In this paper, we model the unknown true function and their approximate functions by multi-fidelity Gaussian process regression, based on which we propose an entropy-based active level set estimation method for cost-effective exploration. We demonstrate efficiency of our approach based on a parameter exploration problem in material science. |
