WebThe performance of t-SNE is fairly robust under different settings of the perplexity. The most appropriate value depends on the density of your data. Loosely speaking, one could say that a larger / denser dataset requires a larger perplexity. Typical values for the perplexity range between 5 and 50.

WebFinally, the TSNE algorithm itself is also computationally intensive, irrespective of the nearest neighbors search. So speeding-up the nearest neighbors search step by a factor of 5 would not result in a speed up by a factor of 5 for the overall pipeline.
