Class QuantizationError

  • All Implemented Interfaces:
    MapDataVisualization

    public class QuantizationError
    extends java.lang.Object
    implements MapDataVisualization
    Computes the quantization error histogram. Each bin will contain the average of the distances between samples mapped to the corresponding unit and the weight vector of that unit.
    Since:
    3.6
