WebJun 5, 2012 · OPTICS algorithm seems to be a very nice solution. It needs just 2 parameters as input (MinPts and Epsilon), which are, respectively, the minimum number of points needed to consider them as a cluster, and the distance value used to compare if two points are in can be placed in same cluster. My problem is that, due to the extreme variety of the ... WebOPTICS Clustering Algorithm Simulation; Improving on existing Visualizations. OPTICS builds upon an extension of the DBSCAN algorithm and is therefore part of the family of hierarchical clustering algorithms. It should be possible to draw inspiration from well established visualization techniques for DBSCAN and adapt them for the use with OPTICS.
