Incorporating prior knowledge into Bayesian models for genetic evaluation in soybean breeding [PDF]

open access: yesPesquisa Agropecuária Brasileira
The objective of this work was to compare the use of noninformative and informative priors in Bayesian models, as well as to evaluate the viability of including informative priors in the estimation of variance components and genetic values in soybean ...

Optimality of Thompson Sampling with Noninformative Priors for Pareto Bandits

open access: yesCoRR, 2023
In the stochastic multi-armed bandit problem, a randomized probability matching policy called Thompson sampling (TS) has shown excellent performance in various reward models. In addition to the empirical performance, TS has been shown to achieve asymptotic problem-dependent lower bounds in several models.

Constrained noninformative priors [PDF]

open access: yes, 1994
The Jeffreys noninformative prior distribution for a single unknown parameter is the distribution corresponding to a uniform distribution in the transformed model where the unknown parameter is approximately a location parameter. To obtain a prior distribution with a specified mean but with diffusion reflecting great uncertainty, a natural ...

A Bayesian Approach to Kriging Metamodeling for Computer Experiments

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
In this paper, an efficient and effective Gaussian Kriging metamodeling approach is proposed in the framework of Bayesian maximum a posterior. Different prior densities and particularly, a Jeffreys' noninformative density based hierarchical prior is

MIMO Radar Imaging With Multiple Probing Pulses for 2D Off-Grid Targets via Variational Sparse Bayesian Learning

open access: yesIEEE Access, 2020
Spatial sparsity of the target space has been successfully exploited to provide accurate range-angle images by the methods based on sparse signal reconstruction (SSR) in Multiple-Input Multiple-Output (MIMO) radar imaging applications.

A Bayesian-Weighted Inverse Gaussian Regression Model with Application to Seismological Data

open access: yesAdvances in Mathematical Physics, 2022
Developing an efficient model for analyzing right-skewed positive observations has a long history, and many authors have attempt in this direction. This is because the common analytic modeling procedures such as linear regression are often inappropriate ...

Estimation of the scale parameter of gamma model in presence of outlier observations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
This paper considers the Bayesian point estimation of the scale parameter for a two-parameter gamma life-testing model in presence of several outlier observations in the data.

Rationale and Design of the Randomized Bayesian Multicenter COME-TAVI Trial in Patients With a New Onset Left Bundle Branch Block

open access: yesCJC Open, 2023
Patients with new-onset left bundle branch block (LBBB) after transcatheter aortic valve implantation (TAVI) are at risk of developing delayed high-degree atrioventricular block. Management of new-onset LBBB post-TAVI remains controversial.
