as_task_torch: Create a Generic Torch Task

In mlr3torch: Deep Learning with 'mlr3'

Create a Generic Torch Task

Description

Creates a TaskTorch, the general-purpose task type of mlr3torch, from a data.frame() or a DataBackend. See the Custom Learning Problems article for more information.

Usage

as_task_torch(x, target = NULL, id = deparse(substitute(x))[1L], ...)

Arguments

x	(data.frame() or DataBackend) The data.
target	(character() or NULL) The names of the target columns. NULL (default) for a task without a target, see section Tasks without a Target of TaskTorch.
id	(character(1)) The id of the task.
...	(any) Further arguments passed to TaskTorch⁠$new()⁠, such as output_dim, default_encoder, default_target_batchgetter or default_measure.

Value

TaskTorch

Examples

# multi-output regression
d = data.frame(x = rnorm(50))
d$y1 = d$x + rnorm(50)
d$y2 = 2 * d$x + rnorm(50)
as_task_torch(d, target = c("y1", "y2"))

# unsupervised: no target at all
as_task_torch(data.frame(a = rnorm(50), b = rnorm(50)))
