From the paper dbscan: Fast Density-Based Clustering with R (page 11) To find a suitable value for eps, we can plot the points’ kNN distances (i.e., the distance of each point to its k-th nearest neighbor) in decreasing order and look for a knee in the plot. The idea behind this heuristic is that points located inside of clusters ... paige harding and bio
