Trying to resolve #8546

Added some more discussion on the intuition behind perplexity, and when and why you may wish to increase it. Also linked to the "How to Use t-SNE Effectively" page.

Comment thread doc/modules/manifold.rst Outdated
can approximate larger regions by a single point,leading to better speed
but less accurate results.
