Examples

if (FALSE) { # \dontrun{
dt = download_zenodo_record(record_id = 4656222, dataset_name = "m3_yearly_dataset")

# optional renaming
setnames(dt, c("id", "date", "value"))

# transform into single task
task = as_task_fcst(dt)

# or split up for forecast learners that don't allow key columns
tasks = as_tasks_fcst(split(dt, by = "id", keep.by = FALSE))

# benchmark

resampling = rsmp("fcst.holdout", ratio = 0.8)
design = benchmark_grid(tasks, learners, resampling)
bmr = benchmark(design)
bmr$aggregate(msr("regr.rmse"))[, .(rmse = mean(regr.rmse)), by = learner_id]
