• Have I written custom code (as opposed to using a stock
  example script provided in TensorFlow): Yes

(e.g. for links and images), because some of these examples are now being rendered in the docs.

Follows from #17387

Suggest a potential alternative/fix

Stop referencing preprocessing functions e.g. :

maxabs_scale
minmax_scale
normalize
quantile_transform
robust_scale
scale
power_transform

in the UG, and only add them e.g. in the "See Also" sections, or even just in the API ref.

In particular right now the first entr

This makes it extremely slow for large sparse matrices. It would be better to compute the extrema of the nonzeros and then account for the zeros (if there are zeros).

Kind regards,
