Hallo Claude,
so etwas?
DBSCAN(D, eps, MinPts)
C = 0
for each unvisited point P in dataset D
mark P as visited
N = doRangeQuery(P, eps)
if sizeof(N) < MinPts
mark P as NOISE
else
C = next cluster
expandCluster(P, N, C, eps, MinPts)
expandCluster(P, N, C, eps, MinPts)
add P to cluster C
for each point P' in N
if P' is not visited
mark P' as visited
N' = doRangeQuery(P', eps)
if sizeof(N') >= MinPts
N = N joined with N'
if P' is not yet member of any cluster
add P' to cluster C
(noch kein VBA) nur aus WIKIPEDIA als Ansatz
Gruß Detlev
