Title: Parameterized Reporting in R Markdown

Abstract: Elizabeth’s talk will focus on how to take customizability of your R Markdown reports to the next level with the help of parameters. Parameters allow the user to change certain aspects of their report without having to go back and make changes within the R Markdown document itself. This is very helpful when producing the same report but under different conditions/assumptions.

Title: Become a Superlearner: Using sl3 to build ensemble learning models

Abstract: Kat will discuss ensemble machine learning in R. Ensemble models combine multiple models to create a stronger overall prediction model. She will give an overview of ensemble learning methods and the packages available in R. She will then focus on understanding and using one algorithm for ensemble learning – stacking, or superlearning – through the R package sl3
