public class MOAClusterer
extends AbstractTransformer

Trains a MOA clusterer based on the incoming data.

Input/output:
- accepts:
weka.core.Instance
adams.flow.core.Unknown
- generates:
adams.flow.container.ModelContainer
moa.clusterers.Clusterer

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: MOAClusterer
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
 

-clusterer <moa.options.ClassOption> (property: clusterer)
    The MOA clusterer to train on the input data and outputs the built clusterer
    alongside the training header (in a model container).
    If the incoming token does not encapsulate an weka.core.Instance, then only
    a new instance of the clusterer is sent around.
    default: moa.clusterers.CobWeb
 

-output-interval <int> (property: outputInterval)
    The number of tokens to wait before forwarding the trainined clusterer.
    default: 1000
    minimum: 1
