mlr_learners_surv.svm: Survival Support Vector Machine Learner

In RaphaelS1/mlr3learners.ranger: Learners from the {survivalsvm} package for 'mlr3'

Description

A mlr3proba::LearnerSurv implementing svm from package survivalsvm. Calls survivalsvm::survivalsvm().

Details

Four possible SVMs can be implemented, dependent on the type parameter. These correspond to predicting the survival time via regression (regression), predicting a continuous rank (vanbelle1, vanbelle2), or a hybrid of the two (hybrid). Whichever type is chosen determines how the crank predict type is calculated, but in any case all can be considered a valid continuous ranking.

Dictionary

This Learner can be instantiated via the dictionary mlr_learners or with the associated sugar function lrn():

mlr_learners$get("surv.svm")
lrn("surv.svm")
