Cross-Validated GLM with Elastic Net Regularization Survival Learner
Source:R/learner_glmnet_surv_cv_glmnet.R
mlr_learners_surv.cv_glmnet.Rd
Generalized linear models with elastic net regularization.
Calls glmnet::cv.glmnet()
from package glmnet.
Prediction types
This learner returns three prediction types:
lp
: a vector containing the linear predictors (relative risk scores), where each score corresponds to a specific test observation. Calculated usingglmnet::predict.cv.glmnet()
.crank
: same aslp
.distr
: a survival matrix in two dimensions, where observations are represented in rows and time points in columns. Calculated usingglmnet::survfit.cv.glmnet()
. Parametersstype
andctype
relate to howlp
predictions are transformed into survival predictions and are described insurvival::survfit.coxph()
. By default the Breslow estimator is used for computing the baseline hazard.

Offset
If a Task
contains a column with the offset
role, it is automatically
incorporated during training via the offset
argument in glmnet::glmnet()
.
During prediction, the offset column from the test set is used only if
use_pred_offset = TRUE
(default), passed via the newoffset
argument in glmnet::predict.coxnet()
.
Otherwise, if the user sets use_pred_offset = FALSE
, a zero offset is applied,
effectively disabling the offset adjustment during prediction.
