Constructor Detail

AggregateKMeansResponse

public AggregateKMeansResponse()

Constructs an AggregateKMeansResponse object with default parameters.

Method Detail

getClassSchema

public static org.apache.avro.Schema getClassSchema()

This method supports the Avro framework and is not intended to be called directly by the user.

Returns:

the schema for the class.

getMeans

public List<List<Double>> getMeans()

Returns:

The k-mean values found.

setMeans

public AggregateKMeansResponse setMeans(List<List<Double>> means)

Parameters:

means - The k-mean values found.

Returns:

this to mimic the builder pattern.

getCounts

public List<Long> getCounts()

Returns:

The number of elements in the cluster closest the corresponding k-means values.

setCounts

public AggregateKMeansResponse setCounts(List<Long> counts)

Parameters:

counts - The number of elements in the cluster closest the corresponding k-means values.

Returns:

this to mimic the builder pattern.

getRmsDists

public List<Double> getRmsDists()

Returns:

The root mean squared distance of the elements in the cluster for each of the k-means values.

setRmsDists

public AggregateKMeansResponse setRmsDists(List<Double> rmsDists)

Parameters:

rmsDists - The root mean squared distance of the elements in the cluster for each of the k-means values.

Returns:

this to mimic the builder pattern.

getCount

public long getCount()

Returns:

The total count of all the clusters - will be the size of the input table.

setCount

public AggregateKMeansResponse setCount(long count)

Parameters:

count - The total count of all the clusters - will be the size of the input table.

Returns:

this to mimic the builder pattern.

getRmsDist

public double getRmsDist()

Returns:

The sum of all the rms_dists - the value the k-means algorithm is attempting to minimize.

setRmsDist

public AggregateKMeansResponse setRmsDist(double rmsDist)

Parameters:

rmsDist - The sum of all the rms_dists - the value the k-means algorithm is attempting to minimize.

Returns:

this to mimic the builder pattern.

getTolerance

public double getTolerance()

Returns:

The distance between the last two iterations of the algorithm before it quit.

setTolerance

public AggregateKMeansResponse setTolerance(double tolerance)

Parameters:

tolerance - The distance between the last two iterations of the algorithm before it quit.

Returns:

this to mimic the builder pattern.

getNumIters

public int getNumIters()

Returns:

The number of iterations the algorithm executed before it quit.

setNumIters

public AggregateKMeansResponse setNumIters(int numIters)

Parameters:

numIters - The number of iterations the algorithm executed before it quit.

Returns:

this to mimic the builder pattern.
