On Natural Representations of Objects

8 pagesPublished: June 22, 2012


We give explanations on the differences between a number of representations that have been proposed in the literature to measure the structural complexity of an object. In particular, we propose the notion of process complexity, the notion of sophistication from a given perspective, the notion of sophisticated depth, and the notion of self-dissimilarity. We also propose the notion of an approximate process for an object and argue that for all practical purposes, an approximate process is as good as an exact process.

Keyphrases: Kolmogorov complexity, meaningful information, Natural representation, positive and negative randomness
