lsdbc {lsdbc}

Locally Scaled Density Based Clustering

Description

Generate a locally scaled density based clustering as proposed by Bicici and Yuret (2007).

Usage

lsdbc(data, k, alpha, jarak = c("euclidean", "manhattan", "canberra", "geodesic"))

Arguments

data

Dataset consists of two variables (x,y) indicating coordinates of each data (point)

k

Number of neighbor to be considered

alpha

Parameter for determining local maximum

jarak

Type of distance to be used, the options are c("euclidean", "manhattan", "canberra", "geodesic")

Value

This function returns a list with the following objects:

data

a dataframe of the dataset used.

cluster

an integer vector coding cluster membership, 0 indicates a noise and cluster start at 1.

parameter

consist of parameter k and alpha.
