Method Details

getK

int getK()

getMinDivisibleClusterSize

double getMinDivisibleClusterSize()

k

IntParam k()

The desired number of leaf clusters. Must be > 1. Default: 4. The actual number could be smaller if there are no divisible leaf clusters.

Returns:

(undocumented)

minDivisibleClusterSize

DoubleParam minDivisibleClusterSize()

The minimum number of points (if greater than or equal to 1.0) or the minimum proportion of points (if less than 1.0) of a divisible cluster (default: 1.0).

Returns:

(undocumented)

validateAndTransformSchema

StructType validateAndTransformSchema(StructType schema)

Validates and transforms the input schema.

Parameters:

schema - input schema

Returns:

output schema
