Checks: 2 0

Knit directory: BOSS_website/

This reproducible R Markdown analysis was created with workflowr (version 1.7.1). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.

R Markdown file: up-to-date

Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.

Repository version: 3995de1

Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.

The results in this page were generated with repository version 3995de1. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.

Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:

Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.

These are the previous versions of the repository in which changes were made to the R Markdown (analysis/index.Rmd) and HTML (docs/index.html) files.

For an overview of BOSS, see this paper.

Examples:

Here is a basic reproducible example of the BOSS algorithm, which illustrates the performance of the BOSS algorithm when the true posterior has different shapes.

These more advanced examples aim to provide the readers some further understanding of the BOSS algorithm and its applications, by replicating the results from the paper.

Discussion on Diagnostic of BOSS:

To guide the readers with the practical implementation of the BOSS algorithm, we provide a discussion on some possible diagnostic tools that can be used to assess the convergence of BOSS.

In addition, we also provide readers with some intuition in terms of the convergence performance of BOSS with respect to the dimension of the conditioning parameter as well as hyper-parameter \(\delta\) of the BOSS algorithm.

Background Readings:

Our implementation of the BOSS is grounded in the framework of Bayesian hierarchical models, specifically the conditional Latent Gaussian Models (cLGMs).

Approximate Bayesian inference for LGMs typically relies on the Laplace approximation and Adaptive Gauss-Hermite Quadrature (AGHQ). For readers less familiar with these concepts, we recommend the following resources:

For readers seeking a deeper understanding of Gaussian processes and the Bayesian optimization algorithm, which are central to the BOSS framework, we recommend the following books:
