mlr_graphs_survaverager: Survival Prediction Averaging Pipeline

In mlr3proba: Probabilistic Supervised Learning for 'mlr3'

Survival Prediction Averaging Pipeline

Description

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
