Survival Prediction Averaging Pipeline

Wrapper around PipeOpSurvAvg to simplify Graph creation.

Usage

pipeline_survaverager(learners, param_vals = list(), graph_learner = FALSE)

Arguments

learners

(list())
List of LearnerSurvs to average.

param_vals

(list())
Parameters, including weights, to pass to PipeOpSurvAvg.

graph_learner

logical(1)
If TRUE returns wraps the Graph as a GraphLearner otherwise (default) returns as a Graph.

Value

mlr3pipelines::Graph or mlr3pipelines::GraphLearner
