%description
A regression and classification algorithm based on random forests, which
takes the form of a short list of rules. SIRUS combines the simplicity of
decision trees with a predictivity close to random forests. The core
aggregation principle of random forests is kept, but instead of
aggregating predictions, SIRUS aggregates the forest structure: the most
frequent nodes of the forest are selected to form a stable rule ensemble
model. The algorithm is fully described in the following articles: Benard
C., Biau G., da Veiga S., Scornet E. (2021), Electron. J. Statist.,
15:427-505 <DOI:10.1214/20-EJS1792> for classification, and Benard C.,
Biau G., da Veiga S., Scornet E. (2021), AISTATS, PMLR 130:937-945
<http://proceedings.mlr.press/v130/benard21a>, for regression. This R
package is a fork from the project ranger
(<https://github.com/imbs-hl/ranger>).
