# Does t-SNE have to result in clear clusters / structures?

I have a data set which, no matter how I tune t-SNE, won't end in clearly separate clusters or even patterns and structures. Ultimately, it results in arbitrary distributed data points all over the plot with some more data points of the one class there and some of another one somewhere else.

Is it up to t-SNE, me and/or the data?

I'm using

Rtsne(df_tsne
, perplexity = 25
, max_iter = 1000000
, eta = 10
, check_duplicates = FALSE)
