Re: are there any "parametric" dictionary compression algorithms?

You are using it in almost the same sense, except that in audio/video coding the parametric models are provided and you want to learn them from the data.

finding the right "functions" would be
horrendously slow and difficult.

If those functions even exist. In audio/video coding they of course do, in natural languages? Doubt it.

I don't see why you are so down on dictionary coding. With a "large enough" history/dictionary and order it can be optimal. All a parametric model does is give you reduced memory requirements and sped up adaption.
