Knowledge-Guided Regularized Random Forests (Know-GRRF)

  • Know-GRFF incorporates domain knowledge in a random forest framework for feature selection.
  • It combines prior information from multiple domains and concurrently optimizes the weight given to each type of domain knowledge.
  • The method is available as the KnowGRFF package in the R/CRAN archive (https://cran.r-project.org/web/packages/KnowGRRF/index.html)
