Assessments of epistemic uncertainty using Gaussian stochastic weight averaging for fluid-flow regression

no code implementations16 Sep 2021 Masaki Morimoto, Kai Fukami, Romit Maulik, Ricardo Vinuesa, Koji Fukagata

The average of such an ensemble can be regarded as the `mean estimation', whereas its standard deviation can be used to construct `confidence intervals', which enable us to perform uncertainty quantification (UQ) with regard to the training process of neural networks.

Convolutional neural networks for fluid flow analysis: toward effective metamodeling and low-dimensionalization

no code implementations7 Jan 2021 Masaki Morimoto, Kai Fukami, Kai Zhang, Aditya G. Nair, Koji Fukagata

We then discuss the influence of various parameters and operations on the CNN performance, with the utilization of autoencoder (AE).
