"response" prediction is a weighted average of the incoming
"se" prediction is currently not aggregated but discarded if present.
Weights can be set as a parameter; if none are provided, defaults to equal weights for each prediction. Defaults to equal weights for each model.
PipeOpRegrAvg$new(innum = 0, collect_multiplicity = FALSE, id = "regravg", param_vals = list())
Determines the number of input channels. If
innum is 0 (default), a vararg input channel is created that can take an arbitrary number of inputs.
TRUE, the input is a
Multiplicity collecting channel. This means, a
Multiplicity input, instead of multiple normal inputs, is accepted and the members are aggregated. This requires
innum to be 0.
Identifier of the resulting object, default
param_vals :: named
List of hyperparameter settings, overwriting the hyperparameter settings that would otherwise be set during construction. Default
