A set of input parameters for const.
This endpoint runs the k-means algorithm - a heuristic algorithm that attempts to do k-means clustering. An ideal k-means clustering algorithm selects k points such that the sum of the mean squared distances of each member of the set to the nearest of the k points is minimized. The k-means algorithm however does not necessarily produce such an ideal cluster. It begins with a randomly selected set of k points and then refines the location of the points iteratively and settles to a local minimum. Various parameters and options are provided to control the heuristic search.
NOTE: The Kinetica instance being accessed must be running a CUDA (GPU-based) build to service this request.

Constructs an AggregateKMeansRequest object with the specified parameters.
[in] | tableName_ | Name of the table on which the operation will be performed. Must be an existing table or collection. |
[in] | columnNames_ | List of column names on which the operation would be performed. If n columns are provided then each of the k result points will have n dimensions corresponding to the n columns. |
[in] | k_ | The number of mean points to be determined by the algorithm. |
[in] | tolerance_ | Stop iterating when the distances between successive points is less than the given tolerance. |
[in] | options_ | Optional parameters.
