Driven by Compression Progress: A Simple Principle Explains Essential Aspects of Subjective Beauty, Novelty, Surprise, Interestingness, Attention, Curiosity, Creativity, Art, Science, Music, Jokes
Paper on arxiv.org, PDF available for free therein
Here’s the paper abstract, lightly reformatted for readability:
I argue that data becomes temporarily interesting by itself to some self-improving, but computationally limited, subjective observer once he learns to predict or compress the data in a better way, thus making it subjectively simpler and more beautiful.
Curiosity is the desire to create or discover more non-random, non-arbitrary, regular data that is novel and surprising not in the traditional sense of Boltzmann and Shannon but in the sense that it allows for compression progress because its regularity was not yet known.
This curiosity drive maximizes interestingness, the first derivative of subjective beauty or compressibility, that is, the steepness of the learning curve.
It motivates exploratory infants, mathematicians, composers, artists, dancers, comedians, yourself, and (since 1990) artificial intelligence.
I read this mid-2019:
And three times since then. Whenever I re-read a paper, I add the date to it. Here’s it’s current state:

The abstract was hard for me to read the first time. I had to re-read it a few different times. Here it is, with my thoughts between sentences:

A self-improving, computationally limited, subjective observer is a fancy way of saying “a normal person”. I’m a self-improving, computationally limited, subjective observer.
I feel a little dose of dopamine in my brain when I encounter novel information, and I have learned to predicted it or anticipate it better than I think I would have. A sign of “better prediction” or “compression” is when I can name a principle elucidated by an author or a known phenomena that is a likely precipitating cause for the unfolding of the story/event.
Curiosity is the desire to create or discover more non-random, non-arbitrary, regular data that is novel and surprising not in the traditional sense of Boltzmann and Shannon but in the sense that it allows for compression progress because its regularity was not yet known.
Do you know that reference? I have no idea who Boltzmann is, but I happen to know who Shannon is, and because I know what is being implied this entire paper takes on a new light.
Shannon is an incredible figure. I’d encourage you to read A Mind At Play: How Claude Shannon Invented the Information Age. It’s fascinating. His life, and his approach to life and his research, is interesting, in the same recursive way that this entire paper I’m discussing is interesting.
This drive maximizes interestingness, the first derivative of subjective beauty or compressibility, that is, the steepness of the learning curve.
The “steepness of the learning curve” is in the same sense that the slope is more important than the y-intercept. (Click that link, read the talk. It’s important to understand the implications for having “the steepest learning curve possible”)
This “steepness” piece, combined with the idea of “compressibility”, posits that they’re inextricably linked. The person who finds the best means to compress information learns the fastest, and therefore outperforms all others in medium-to-long time horizons.
It motivates exploring infants, pure mathematicians, composers, artists, dancers, comedians, yourself, and (since 1990) artificial systems.
The conclusion of the abstract ties in this (admittedly dense) topic of “compression progress” to the domain of all of us.
Anyone engaged in pure research should read this. Anyone who creates anything (words, jokes, code) should attend to the idea of “compression progress”. To attend to this compression is to engage in learning and exploration in the most effective way possible.
Incidentally, for examples of persons driven by compression progress, we can all turn to infants, and observe how they explore the world.
Conclusion
I’ll probably pull out quotes from the paper at some point. Download the paper and skim the table of contents.
