A Passive Source Location Method in a Shallow Water Waveguide with a Single Sensor Based on Bayesian Theory
Published 2019-03-01“…In this paper, the source location was transformed to the inversion of the source location and environmental parameters, which can be estimated accurately based on the multi-dimensional posterior probability density (PPD). This method is less limited by environmental factors, and the accuracy of inversion results can be analyzed according to the PPD of inversion parameters, which has higher reliability and a wider application scope. …”

Bland–Altman Limits of Agreement from a Bayesian and Frequentist Perspective

Overview of Research on Bayesian Inference and Parallel Tempering
Published 2023-02-01“…Bayesian inference is one of the main problems in statistics.It aims to update the prior knowledge of the probability distribution model based on the observation data.For the posterior probability that cannot be observed or is difficult to directly calculate,which is often encountered in real situations,Bayesian inference can obtain a good approximation.It is a kind of important method based on Bayesian theorem.Many machine learning problems involve the process of simulating and approximating the target distribution of various types of feature data,such as classification models,topic modeling,and data mining.Therefore,Bayesian inference has shown important and unique research value in the field of machine learning.With the beginning of the big data era,the experimental data collected by researchers through actual information is very large,resulting in the complex distribution of targets to be simulated and calculated.How to perform accurate and time-efficient approximation inferences on target distributions under complex data has become a major and difficult point in Bayesian inference problems today.Aiming at the infe-rence problem under this complex distribution model,this paper systematically introduces and summarizes the two main methods for solving Bayesian inference problems in recent years,which are variational inference and sampling methods.Firsly,this paper gives the problem definition and theoretical knowledge of variational inference,introduces in detail the variational inference algorithm based on coordinate ascent,and gives the existing applications and future prospects of this method.Next,it reviews the research results of existing sampling methods at home and abroad,gives the specific algorithm procedure of various main sampling methods,as well as summarizes and compares the characteristics,advantages and disadvantages of these methods.Finally,this paper introduces parallel tempering technique,outlines its basic theories and methods,discusses the combination and application of parallel tempering and sampling methods,and explores new research directions for the future development of Bayesian inference problems.…”
