Tackling Epistemic and Aleatoric Forecast Errors in Wave Phenomena using Observations, Models, and Diffusion Map Machine Learning
EFFICIENT DATA-DRIVEN METHODS FOR MULTISCALE STOCHASTIC MODELING AND UNCERTAINTY QUANTIFICATION I ORAL
nonlinear geophysics | 13 december 2023
Juan M. Restrepo, Jorge M. Ramirez
Time dependent data assimilation is a well established Bayesian estimation strategy that take into account aleatoric errors in observations and models...

Homotopy Sampling, with an Application to Particle Filters
ADVANCES IN DATA ASSIMILATION, PREDICTABILITY, AND UNCERTAINTY QUANTIFICATION II ORAL
nonlinear geophysics | 14 december 2021
Juan M. Restrepo, Jorge M. Ramirez
We describe a homotopy sampling procedure, loosely based on importance sampling. Starting from a known probability distribution, the homotopy procedur...

Global Climate Change Forecasting Under Uncertainties
CENTENNIAL SESSION: COMPLEXITY OF NONLINEAR GEOPHYSICS: PAST ACCOMPLISHMENTS AND FUTURE CHALLENGES WITH AN EMPHASIS ON URBAN GEOSCIENCES I
nonlinear geophysics | 09 december 2019
Juan M. Restrepo, Michael E. Mann
'Climate is always changing' and 'it is not possible to make global climate forecasts due to uncertainties' are two widely held societal opinions that...
