    Yet, the perplexity is 2 −0.9 log 2 0.9 - 0.1 log 2 0.1 = 1.38. The inverse of the perplexity, 1/1.38 = 0.72, does not correspond to the 0.9 probability. The perplexity is the exponentiation of the entropy, a more straightforward quantity.

    The perplexity is a hand-chosen parameter of t-SNE, and as the authors state, "perplexity can be interpreted as a smooth measure of the effective number of neighbors. The performance of SNE is fairly robust to changes in the perplexity, and typical values are between 5 and 50.". [2]

    And since perplexity.ai can write in wiki text, you can also store its results in your wiki, such as tables you make with it. Bitnami makes it easier because it packages all the prerequisite software needed to run MediaWiki (such as a webserver) along with MediaWiki and an installer program, reducing the whole operation to a series of clicks.
