I'm warming up for a new iteration over the topic and already have insights and challenges to pose [writing in progress], on second read, I see the paper has some profoundly confused concepts. In general my view matches Schmidhuber's view for cognitive beauty as compression/compression progress and balance of predictability, but there are some crucial concepts and parameters that need to be specified and are obvious in the case of music. I've shared some general thoughts in discussions on the AGIRI AGI list also. It will be continued more formally and technically in a paper, with some details that I deliberately omitted while writing this email.
I'm Todor Arnaudov, I'd say a veteran AGI/SIGI* interdisciplinary researcher, an extreme polymath and universal artist, I do constantly progress my art, knowledge and skills in all kinds of sciences (soft- and hard-), technical fields and arts - both creative and performance, covering all sensori-motor domains.
First of all, congratulations for presenting those ideas together!
I write you, because I happen to have made related, similar or in cases the same hypotheses and speculations regarding general intelligence (all domains) and creativity starting in the early 2000s, mostly between mid-2002 and early 2004, which represented my Theory of intelligence and creativity (originality); it's also metaphysical and digital-physics/philosophy.
My theory is about prediction/compression with increasing range or precision, the balance (too predictable is boring, too unpredictable is "random") and also compression progress (progress of predictions' range and precision) as basic cognitive and aesthetic drives in all domains; the cognitive "uglyness" as cognitive overload and beauty/intelligence as finding simple matches/transformations.
I do also discriminate between cognitive and physical beauty (physical one is actually just pleasure), what you call "2) stimulating the receiver through historical association" in my view is again related to physical beauty, experienced in the past, and associated with cognitive stimuli, which makes the cognitive stimuli to invoke those physical memories. Both types are often confused due to the mess in the brain reward systems (dopamine-and-other neurotransmitters and the intrinsic cognitive reward or prediction/compression), and people use to call "beautiful" stimuli which are just pleasant, i.e. produce a release of dopamine, oxytocin, endorphines etc.
I also have claimed and held that the science and arts are "the same thing"** beginning from those a decade old works, to me it has been obvious, because I've been always doing both. I don't mean Schmidhuber's "low complexity art", but "high complexity" art, i.e. normal classical art, good old fashioned drawing, artistic photography, writing, music, acting, filmmaking - all kinds of stuff, genres, forms, lengths.
drawings use just lines - therefore [perhaps]
That parallel part in the original, below the BW picture with the list of words, which I've missed to translate in that edition says:
occupies just 10% more space on my hard drive* [than the picture of the other building], however it brings much more meaningful information.
- a grass field
- bushes - branches, leaves
- a tree - stem, branches, leaves
- house - roof with tiles; second floor with a terrace, having a rail; other windows on the second floor (each of them is a "piece of knowledge in the picture)
- windows on the first floor
- reflections on the pavement
- water covering the pavement [causing the reflections]
- that water implies rain
- children (bottom left)
- a bench (in the middle) built of two supports and a board [actually two benches]
- a sky- a rectangular building- windows (the same type)- several floors- repeating bar of windows, put in perspective, but it looks "flat" because is on the same plane, there are no big perpendicular planes like in the other picture, which looks in 3D
Now I see that in fact this 10% covers approximately the difference of the pictures' resolutions (the BW pictures is slightly bigger), which emphasizes the differences in "meaningful knowledge".
Well, that all is inspiring me to do another, more elaborate and detailed iteration.
