Bayesian Spatial Uncertainty Analysis

The term uncertainty originates from imperfect knowledge of the processes under question. These errors are sometimes associated with questionable data quality and scarcity; complexity of the phenomena that are treated by models as simplified systems. Important components of uncertainty analysis include (i) qualitative analysis that identifies the uncertainties, (ii) quantitative analysis of the...

Galaxy Formation: Bayesian History Matching for the Observable Universe

Understanding the evolution of the Universe from the Big Bang to the current day is the fundamental goal of cosmology. A major part of this is the problem of structure formation: understanding the formation, growth and subsequent evolution of galaxies in the presence of Dark Matter. The world leading Galform group, based at the Institute of Computational Cosmology, Durham University, has develo...

Bayesian Switching Interaction Analysis Under Uncertainty

We introduce a Bayesian discrete-time framework for switching-interaction analysis under uncertainty, in which latent interactions, switching pattern and signal states and dynamics are inferred from noisy (and possibly missing) observations of these signals. We propose reasoning over full posterior distribution of these latent variables as a means of combating and characterizing uncertainty. Th...

Joint Bayesian Stochastic Inversion of Well Logs and Seismic Data for Volumetric Uncertainty Analysis

Here in, an application of a new seismic inversion algorithm in one of Iran’s oilfields is described. Stochastic (geostatistical) seismic inversion, as a complementary method to deterministic inversion, is perceived as contribution combination of geostatistics and seismic inversion algorithm. This method integrates information from different data sources with different scales, as prior informat...
