We present a framework for automatically structuring and training fast, approximate, deep neural surrogates of existing stochastic simulators. Unlike traditional approaches to surrogate modeling, our surrogates retain the interpretable structure of the reference simulators. The particular way we achieve this allows us to replace the reference simulator with the surrogate when undertaking amortized inference in the probabilistic programming sense. The fidelity and speed of our surrogates allow fo...

Abstract Analysis of the fibre dominated properties of composite materials typically assumes, often implicitly, the perfect alignment of fibres. Increasingly, however, it is acknowledged that waviness (in-plane misalignment) and wrinkling (out-of-plane misalignment) play an important role in both manufacturing and structural response. In this paper, a previously developed experimental method to measure fibre misalignment has been improved and extended to also determine fibre excess length. Resul...
