Hi Arvind,
I assume you use the refactored classes in the o.a.c.m.ml.clustering
package.
You can use the Clusterer like that:
List<DoublePoint> data = new ArrayList<DoublePoint>();
DBSCANClusterer<DoublePoint> dbscan =
new DBSCANClusterer<DoublePoint>(10,3);
List <Cluster<DoublePoint>> clusters = dbscan.cluster(data);
To use the generic interface Clusterable, the Clusterer interface should
better be like that:
public List<Cluster<T>> cluster(final Collection<? extends T> points)
We will consider this for the next version.
