class UPCGClusterSettings : public UPCGSettings
Remarks
Given a desired number of clusters (categories), find the best fit cluster for each point by distance, using one of various clustering algorithms.
Variables
| Type | Name | Description | |
|---|---|---|---|
    |
EPCGClusterAlgorithm | Algorithm | Mathematical algorithm for selecting clusters. |
    |
bool | bOutputFinalCentroids | Output the final location of the centroids or gaussians. |
    |
FName | ClusterAttribute | Cluster IDs will be written to this attribute on the output. |
    |
int32 | MaxIterations | A limit on the number of iterations to run on each algorithm, if it doesn't otherwise converge. |
     |
int32 | NumClusters | Number of clusters (segments) to group the points into. |
    |
double | Tolerance | For EM, the maximum allowed difference between the last two iterations' "Log Likelihood"which converges from positive infinity to 0 in relation to point-to-cluster probabilities. |

TArray< FPCGPinProperties > | Returns an array of all the input pin properties. You should not add manually a "params" pin, it is handled automatically by FillOverridableParamsPins. | |

bool | UseSeed () |
By default, settings do not use a seed. |
