A New Method for Multinomial Inference using Dempster-Shafer Theory
Earl C. Lawrence, Alexander C. Murph, Scott A. Vander Wiel +1
A new method for multinomial inference is proposed by representing the cell probabilities as unordered segments on the unit interval and following Dempster-Shafer (DS) theory. The…
Relationship-aware Multivariate Sampling Strategy for Scientific Simulation Data
Subhashis Hazarika, Ayan Biswas, Phillip J. Wolfram +2
With the increasing computational power of current supercomputers, the size of data produced by scientific simulations is rapidly growing. To reduce the storage footprint and facil…
An Initial Exploration of Bayesian Model Calibration for Estimating the Composition of Rocks and Soils on Mars
Claire-Alice Hébert, Earl Lawrence, Kary Myers +2
The Mars Curiosity rover carries an instrument, ChemCam, designed to measure the composition of surface rocks and soil using laser-induced breakdown spectroscopy (LIBS). The measur…
Scaled Vecchia approximation for fast computer-model emulation
Matthias Katzfuss, Joseph Guinness, Earl Lawrence
Many scientific phenomena are studied using computer experiments consisting of multiple runs of a computer model while varying the input settings. Gaussian processes (GPs) are a po…
Estimating Scale Discrepancy in Bayesian Model Calibration for ChemCam on the Mars Curiosity Rover
K. Sham Bhat, Kary Myers, Earl Lawrence +2
The Mars rover Curiosity carries an instrument called ChemCam to determine the composition of the soil and rocks. ChemCam uses laser-induced breakdown spectroscopy (LIBS) for this…
The Mira-Titan Universe. III. Emulation of the Halo Mass Function
Sebastian Bocquet, Katrin Heitmann, Salman Habib +5
We construct an emulator for the halo mass function over group and cluster mass scales for a range of cosmologies, including the effects of dynamical dark energy and massive neutri…
