WebMar 23, 2024 · In contrast, van der Maaten and Hinten suggested perplexity should be in the range 5–50, and the sklearn documentation suggests learning rate values in the range 40–4,000 (after adjusting due to difference in implementation). We find those ranges too wide and too large in value to be useful for the data sets that we analyzed.
