A Deep Learning Approach to Probabilistic Forecasting of Weather

1 code implementation23 Mar 2022 Nick Rittler, Carlo Graziani, Jiali Wang, Rao Kotamarthi

We discuss an approach to probabilistic forecasting based on two chained machine-learning steps: a dimensional reduction step that learns a reduction map of predictor information to a low-dimensional space in a manner designed to preserve information about forecast quantities; and a density estimation step that uses the probabilistic machine learning technique of normalizing flows to compute the joint probability density of reduced predictors and forecast quantities.

Simultaneous Reconstruction and Uncertainty Quantification for Tomography

no code implementations29 Mar 2021 Agnimitra Dasgupta, Carlo Graziani, Zichao Wendy Di

Tomographic reconstruction, despite its revolutionary impact on a wide range of applications, suffers from its ill-posed nature in that there is no unique solution because of limited and noisy measurements.

Targeted Adaptive Design

no code implementations27 May 2022 Carlo Graziani, Marieme Ngom

Modern advanced manufacturing and advanced materials design often require searches of relatively high-dimensional process control parameter spaces for settings that result in optimal structure, property, and performance parameters.
