Density
01 Syntax
Microsoft.VisualBasic.DataMining.Clustering.Density
02 Methods
| Name | Overloads | Summary |
|---|---|---|
| GetDensity | 1 | 密度为到k个最近邻的平均距离的倒数。如果该距离小，则密度高 |
| GetDensity | 2 | 密度为到k个最近邻的平均距离的倒数。如果该距离小，则密度高 |

|---|---|---|
dataset | IEnumerable(Of ClusterEntity) | - |
k | Int32 | - |
Returns
a collection of tuple [id -> density]. the larger of the result value, the higher density value it is
