workflowr checks: (Click a bullet for more information)

✔ 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: 6417d4e
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility. The version displayed above was the version of the Git repository at the time these results were generated.

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:    .DS_Store
    Ignored:    .Rhistory
    Ignored:    .Rproj.user/
    Ignored:    docs/.DS_Store
    Ignored:    docs/figure/.DS_Store

Untracked files:
    Untracked:  data/greedy19.rds
    Untracked:  data/greedy22.rds
```
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.

In Progress

Investigation 5. We should change the default init_fn to udv_si_svd when there is missing data and udv_svd otherwise.

Still Relevant

Note 1. Notes on computing the FLASH objective function. I derive an explicit expression for the KL divergence between prior and posterior.

Note 2. An alternate algorithm for optimizing the FLASH objective, using the explicit expression derived in the previous note.

Investigation 4. The alternate algorithm agrees with FLASH with respect to both the objective and fit obtained.

Archived

The bug causing the problem described in Investigations 1-3 was fixed in version 0.1-13 of package ebnm.

Investigation 1. The FLASH objective function can behave very erratically.

Investigation 2. This problem only occurs when using ebnm_pn, not ebnm_ash.

Investigation 3. The objective can continue to get worse as loadings are repeatedly updated. Nonetheless, convergence takes place (from above!).

This reproducible R Markdown analysis was created with workflowr 1.0.1
