Asymptotic inference for mixture models by using data‐dependent priors

TL;DR: In this paper, the authors show that data-dependent priors are the only priors that produce intervals with second-order correct frequentist coverage, and that the resulting posterior is the product of a fixed prior and a pseudolikelihood.

Model-Based Cognitive Neuroscience Approaches to Computational Psychiatry Clustering and Classification

TL;DR: In this article, the authors highlight efforts to overcome current challenges by focusing on the emerging field of computational psychiatry, which might enable the field to move from a symposium to a real world.

A multivariate semiparametric bayesian spatial modeling framework for hurricane surface wind fields

TL;DR: In this paper, a new Bayesian multivariate spatial statistical modeling framework is introduced combining data with physical knowledge about the wind fields to improve the estimation of the wind vectors, which can capture the asymmetric and dynamic nature of a hurricane.

Variational Inference for Infinite Mixtures of Gaussian Processes With Applications to Traffic Flow Prediction

TL;DR: This paper proposes a new variational approximation for infinite mixtures of Gaussian processes that uses variational inference and a truncated stick-breaking representation of the Dirichlet process to approximate the posterior of hidden variables involved in the model.
Proceedings ArticleDOI

The dynamic hierarchical Dirichlet process

TL;DR: The dynamic hierarchical Dirichlet process (dHDP) is developed to model the time-evolving statistical properties of sequential data sets, and a relatively simple Markov Chain Monte Carlo sampler is developed.

A Bayesian Analysis of Some Nonparametric Problems

TL;DR: In this article, a class of prior distributions, called Dirichlet process priors, is proposed for nonparametric problems, for which treatment of many non-parametric statistical problems may be carried out, yielding results that are comparable to the classical theory.

Ferguson Distributions Via Polya Urn Schemes

TL;DR: In this article, it was shown that a random probability measure P* on X has a Ferguson distribution with parameter p if for every finite partition (B1, *. *, B) of X, the vector p*(B,), * * *, p *(B) has a Dirichlet distribution with parameters (Bj), *--, cp(B,) (when p(B), = 0, this means p*) = 0 with probability 1).

Implicit renewal theory and tails of solutions of random equations

TL;DR: For the solutions of certain random equations, or equivalently the stationary solutions of the random recurrences, the distribution tails are evaluated by renewal-theoretic methods as mentioned in this paper.

Bayesian density estimation by mixtures of normal distributions

TL;DR: In this article, a mixture of a countable number of normal distributions is used to estimate a density f(x) on the real line, which is then used for kernel estimation.

On the Asymptotic Behavior of Bayes' Estimates in the Discrete Case

TL;DR: In this article, it was shown that the posterior probability converges to point mass at the true parameter value among almost all sample sequences (for short, the posterior is consistent; see Definition 1) exactly for parameter values in the topological carrier of the prior.
