R code for classifier performance and interestingness measure visualization in 3D barycentric space.

Tetrahedron Measure Visualization

Visualize and analyze measures with respect to complete ranges of their values in a barycentric coordinate system using a 3D tetrahedron. Explore the properties of popular classifier performance (Brzezinski et al., 2018) and rule interestingness measures (Susmaga & Szczech, 2015), or visualize custom functions.

Live app for this code: https://dabrze.shinyapps.io/Tetrahedron/

Running the app

1. First install all the required packages by running install_libraries.R (you can also try to do this manually if you do not want to install a couple of unnecessary dependencies)
2. Open Tetrahedron.Rproj in RStudio
3. Open the ui.R file
4. Press the Run App button

The application works best in a standard browser (rather than RStudio chromium-based viewer). To open the app in a regular browser press the Open in Browser button in the chromium-based viewer or select Run External from the Run App dropdown in Rstudio.

If you do not want to use RStudio, you can use the R console, go into the Tetrahedron directory and run the command shiny::runApp().
