tsne.centralities | R Documentation |
This function applies t-SNE, dimensionality reduction algorithm, on centrality measures.
tsne.centralities(x, dims = 2, perplexity = 5, scale = TRUE)
x |
a list containg the computed cetrality values |
dims |
integer; number of the outpu dimensions(default=2) |
perplexity |
numeric; A flexible measure of the efficient number of neighbors. The performance of SNE is fairly robust to changes in the perplexity, and typical values are between 5 and 50.(default=5) |
scale |
Whether the centrality values should be scaled or not(default=TRUE) |
t-SNE is a non-linear dimensionality reduction algorithm used for exploring high-dimensional data. Here, It maps multi-dimensional centrality measure data to less dimensions suitable to work with it.
It resturns cost plot of tsne results which displays centralities in order of their corresponding costs.
