Impute features by their mode. Supports factors as well as logical and numerical features. If multiple modes are present then imputed values are sampled randomly from them.

`R6Class`

object inheriting from `PipeOpImpute`

/`PipeOp`

.

PipeOpImputeMode$new(id = "imputemode", param_vals = list())

`id`

::`character(1)`

Identifier of resulting object, default`"imputemode"`

.`param_vals`

:: named`list`

List of hyperparameter settings, overwriting the hyperparameter settings that would otherwise be set during construction. Default`list()`

.

Input and output channels are inherited from `PipeOpImpute`

.

The output is the input `Task`

with all affected features missing values imputed by (column-wise) mode.

The `$state`

is a named `list`

with the `$state`

elements inherited from `PipeOpImpute`

.

The `$state$model`

is a named `list`

of a vector of length one of the type of the feature, indicating the mode of the respective feature.

The parameters are the parameters inherited from `PipeOpImpute`

.

Features that are entirely `NA`

are imputed as
the following: For `factor`

or `ordered`

, random levels are sampled uniformly at random.
For logicals, `TRUE`

or `FALSE`

are sampled uniformly at random.
Numerics and integers are imputed as `0`

.

Note that every random imputation is drawn independently, so different values may be imputed if multiple values are missing.
