This graph is split into clusters using modularity optimization techniques. You can tweak the clustring with the resolution parameter to get more/less clusters and also with parameters k and k.scale for the construction of the …
WebNov 18, 2016 · The Rtsne package can be used as shown below. The perplexity parameter is crucial for t-SNE to work correctly – this parameter determines how the local and global aspects of the data are balanced. A more detailed explanation on this parameter and other aspects of t-SNE can be found in this article , but a perplexity value between 30 and 50 is ...
