PipeOpMean_B {NADIA}

PipeOpMean_B

Description

Impute numerical features by their mean in approach B (independently during the training and prediction phase).

Input and Output Channels

Input and output channels are inherited from PipeOpImpute.

Parameters

The parameters include inherited from ['PipeOpImpute'], as well as:

• id :: character(1)
  Identifier of resulting object, default "imput_mean_B".
