This reproducible R Markdown analysis was created with workflowr (version 1.6.2). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
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.
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 0dba088. 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:
Ignored files:
Ignored: .RData
Ignored: .Rhistory
Unstaged changes:
Deleted: analysis/about.Rmd
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/AMSI.Rmd) and HTML (docs/AMSI.html) files. If you’ve configured a remote Git repository (see ?wflow_git_remote), click on the hyperlinks in the table below to view the files as they were in that past version.

This page documents my progress for the research project ‘Variaitonal Inference for Bayesian Nonnegative Matrix Factorization’. This research project is carried out under the AMSI Vacation Scholarship Program, supervised by Dr. Heejung Shim at the University of Melbourne.

Doubly Structured Stochastic Variational Inference (DSSVI) for BP-NMF - Extension of Hoffman and Liang (2014), where an additional sparsity matrix has been added to enforce sparsity in the first factored matrix as well.
