Title: Building trust in neural networks for modelling in engineering
Abstract: While neural networks have empirically shown their performance as non-linear predictors, they suffer from low interpretability, limited out-of-the-box performance guarantees, complex training procedures, and high susceptibility to data corruption and other adversarial attacks. Combined altogether, this results in a low acceptability for application in critical sectors like energy or communication systems. In this context, we propose Wasserstein distributionally robust shallow convex neural networks (WaDiRo-SCNNs) to provide reliable nonlinear predictions when subject to adverse and corrupted datasets. Our training procedure is conservative by design, has low stochasticity, is solvable with open-source solvers, and is scalable to large industrial deployments. Our approach aims to make neural networks safer for critical applications, such as in the energy sector. Finally, we numerically demonstrate the performance of our model on a synthetic experiment and a real-world energy system application, viz., the prediction of non-residential buildings’ hourly energy consumption.
