Abstract:To uncover far/near relations between clusters accurately, existing clustering visualization methods usually have poor effects under the difficult condition of many clusters in a high-dimensional dataset. A new visualization method — line-pearl pattern with (non-) linear coordinates is proposed to show far/near relations or distances between clusters. Its advantage is that it can show far/near relations between clusters accurately under the difficult condition mentioned above. Experimental results on simulated and real data sets show that the proposed method is effective and much better than the clustering visualization methods.
