  • An automatic learning rate finder has been implemented, used by setting learningRate="auto"
  • Training loop parameters are now handled by a new settings object and as a result more of the training loop parameters are customizable by the user
  • Custom metrics can be created by the user to use for early stopping and learning rate schedule.
  • Seeds have been added in various places, making the whole process more reproducible

Thanks to @lhjohn for his contributions to this release.

CohortGenerator v0.8.0 was released a few weeks ago (sorry for the delayed announcement). The release notes are here.

This release of CohortGenerator adds the ability to generate subsets of cohorts. So, for example, if you have a target cohort of new users of a drug, you can use CohortGenerator to define a subset definition to further subset that target based on a combination of demographic criteria, “limit” criteria (i.e. X days of prior observation) and even based on intersection with another cohort definition. Here is the Creating Cohort Subset Definitions vignette if you are interested in the details.

A big thanks to @jpegilbert who lead the development of this important new feature.

Capr v2.0.1 has been released. This is a patch release so no major changes. Updates include:

  • more informative cs print statement
  • other minor bug fixes

Please keep trying out Capr and posting issues! Feedback always welcome!

#137

CohortDiagnostics version 3.2.0. There are no major api changes in this release so all existing scripts should maintain compatibility with this release.

The main changes are as follows:

  • Improved support for Subset operators by fixing some issues around concept sets
  • Added a database migration for existing results databases to support cohort definition sets with subsets
  • Almost all shiny code has been moved to the OhdsiShinyModules package - this is a single package to install and keep up to date
  • Some alterations to plots and tables in the DiagnosticsExplorer shiny app were changed as the ggiraph package was removed due to compatibility and installation issues on Linux environments. All plots now use ggplot2 and/or plotly
  • Support for easier publishing to Posit Connect/Rconnect and shinyapps.io (testing of shinyapps.io was limited as it was a paid service)

Please check the release notes for for details of changes.

ResultModelManager v0.4.0 has been released.
This release adds some vignettes on usage as well as a QueryNamespace class that adds a wrapper around SqlRender functionality that allows execution of queries with fixed parameters from result model specifications.

See this guide on basic usage. The intention is that this will be useful for writing shiny apps and Quatro reports.

In addition, the function createResultsDataModel has been removed as it was added in error when migrating code.

#150

DeepPatientLevelPrediction 1.1.4 has been released. This was a small change needed for running the package with Strategus. Now the device to develop the models on (GPU or CPU) can be controlled with an environment variable in the study package. Before it was hard coded in the study package. But users might want to select a certain GPU to use or even CPU for testing the package.
