Method Detail
-
writeTo
public void writeTo(StreamOutput out) throws java.io.IOException
Description copied from class:MovAvgModel
Write the model to the output stream- Specified by:
writeTo
in interfaceWriteable
- Specified by:
writeTo
in classMovAvgModel
- Parameters:
out
- Output stream- Throws:
java.io.IOException
-
getWriteableName
public java.lang.String getWriteableName()
Description copied from interface:NamedWriteable
Returns the name of the writeable object
-
canBeMinimized
public boolean canBeMinimized()
Description copied from class:MovAvgModel
Returns if the model can be cost minimized. Not all models have parameters which can be tuned / optimized.- Specified by:
canBeMinimized
in classMovAvgModel
-
neighboringModel
public MovAvgModel neighboringModel()
Description copied from class:MovAvgModel
Generates a "neighboring" model, where one of the tunable parameters has been randomly mutated within the allowed range. Used for minimization- Specified by:
neighboringModel
in classMovAvgModel
-
clone
public MovAvgModel clone()
Description copied from class:MovAvgModel
Clone the model, returning an exact copy- Specified by:
clone
in classMovAvgModel
-
doPredict
protected double[] doPredict(java.util.Collection<java.lang.Double> values, int numPredictions)
Description copied from class:MovAvgModel
Calls to the model-specific implementation which actually generates the predictions- Specified by:
doPredict
in classMovAvgModel
- Parameters:
values
- Collection of numerics to movingAvg, usually windowednumPredictions
- Number of newly generated predictions to return- Returns:
- Returns an array of doubles, since most smoothing methods operate on floating points
-
next
public double next(java.util.Collection<java.lang.Double> values)
Description copied from class:MovAvgModel
Returns the next value in the series, according to the underlying smoothing model- Specified by:
next
in classMovAvgModel
- Parameters:
values
- Collection of numerics to movingAvg, usually windowed- Returns:
- Returns a double, since most smoothing methods operate on floating points
