Collage Theorem

A 1985 result in fractal geometry, proved by Michael Barnsley and Stephen Demko, showing that an iterated function system's attractor can be made arbitrarily close to a target image by choosing contraction maps that each place a scaled copy of the whole image close to a piece of itself. It converted fractal self-similarity from a descriptive curiosity into a constructive compression method: find the collage, and you have encoded the image.

Matters to this vault as the specific mathematical hinge Poli et al.'s 2022 Neural Collages paper reframes as a differentiable, hypernetwork-trained operator — the concrete technical object underneath this vault's citation-lineage finding that fractal compression and implicit neural representations are, in one documented instance, treated as the same class of method.
