|
ipSample |
Container holding a single input sample (ContainerType_Vector_REAL or ContainerType_Vector_LREAL) | |
|
hrPrev |

Return valueFurther information
The function F_VN_GetSampleCluster determines the best matching cluster for a sample and returns its ID.
Parameter
Clusterer model
A previously trained model must be transferred to ipClusterer for assignment to clusters.
Sample
A container with a sample is transferred to ipSample. The type of container must be ContainerType_Vector_REAL or ContainerType_Vector_LREAL.
Cluster ID
The ID determined is returned via nCluster.
Expert parameters
The expert variant F_VN_GetSampleClusterExp contains additional parameters.
Application
The assignment of a sample to a cluster can be calculated as follows:
hr := F_VN_GetSampleCluster(
ipClusterer := ipClusterer,
ipSample := ipSample,
nCluster := nCluster,
hrPrev := hr);
