PipeOpQuantileBin$new(id = "quantilebin", param_vals = list())

Input and Output Channels

Input and output channels are inherited from PipeOpTaskPreproc.

The output is the input Task with all affected numeric features replaced by their binned versions.

State

The $state is a named list with the $state elements inherited from PipeOpTaskPreproc, as well as:

Parameters

The parameters are the parameters inherited from PipeOpTaskPreproc, as well as:
