Other clustering algorithms with better features tend to be more expensive. In this case, k-means becomes a great solution for pre-clustering, reducing the space into disjoint smaller sub-spaces …

No need to use a specific binary clustering algorithm. kmeans is simple and clustering 650K vectors should be easily feasible on a decent desktop. 4 - If you wish to have binary cluster vectors as the …

Because of the strong non-linear cluster in the second data set, the linkage and density clustering algorithms work far better than any centroid-based method. There is no similarity measure that will …

For clustering results, usually people compare different methods over a set of datasets which readers can see the clusters with their own eyes, and get the differences between different methods results. …

Mar 12, 2014 · I found this tutorial, which suggests that you should run the scale function on features before clustering (I believe that it converts data to z-scores). I'm wondering whether that is necessary.

Apr 2, 2024 · So I'm doing my bachelor`s work and I'm applying different clustering algorithms on certain data. Before all the clustering of course I'm using a dimensionality reduction algorithm such as t-SNE …

Oct 24, 2016 · Are there any "non-parametric" clustering methods for which we don't need to specify the number of clusters? And other parameters like the number of points per cluster, etc.

Feb 14, 2016 · One might say "the best method of clustering is which gives you the right answer"; but I may question in response that cluster analysis is supposed to be an unsupervised technique - so …

Nov 7, 2016 · Clustering algorithms will always perform much much worse compared to classification methods. If you have labels, use classification or regression instead of clustering!

Jan 27, 2012 · Internal indices are used to measure the goodness of a clustering structure without external information (Tseng et al., 2005). For external indices, we evaluate the results of a clustering …
