Bayesianism is inductivism in a cheap tuxedo. Has nothing to do with creativity. See bretthall.org/bayesian-epist… by @ToKTeacher

@Azaeres @SerhiiHavrylov

The problem with inductive processes is that they don’t exist.

Re intractable: I don’t know what you mean by “holistic nature”, but our minds are creative somehow, so it can’t be intractable. We just don’t yet know how.

Indeed. E.g. for objects in JS, Clojure etc one first needs an explanation of how to map keys reliably to values: a hash function. We know from lambda calculus that any such concepts can be built from pure, single parameter functions, because it is Turing complete.

@DKedmey

Yeah, that’d be pretty neat. Being a universal explainer, the creative algorithm could do so.

@dchackethal · · Show · Open on Twitter

@Doxosophoi

What do you mean by “epistemological facts”? Do you mean rules such as hard to vary? If so, my guess is knowledge of those rules is the result of the creative algorithm as well. If your question is how the creative algorithm creates new explanations, I haven’t covered that yet.

@SerhiiHavrylov

First time reading about this, too. First impression: Sounds like Occam’s razor applied to functions. I’m after good function implementations, which need not be the shortest. The best implementation of multiplication in this episode only happens to be the shortest, IIRC.

@SerhiiHavrylov

First time reading about Solomonoff’s inductive inference, so may be missing something. Wikipedia says it “is a theory of prediction based on logical observations”. Sounds inductive to me. Too focused on observation. No mention of knowledge creation as far as I can tell.

One of the points of h2v is that you don’t even need to bother testing e2v theories.

@dchackethal · · Show · Open on Twitter

@krazyander @ToKTeacher @RealtimeAI @DoqxaScott

You observe a conjuring trick and want to explain how it’s done. The explanation “the conjurer did something” has a lot of “evidential support” - you saw him doing something - but that’s a bad explanation b/c easy to vary. Doesn’t explain what he did and applies to any trick.

Glad to hear! Currently working on episode five, which will be about how the epistemological concepts we covered in episode four apply to computer programs and what that means. Hopefully ready to release soon!

@dchackethal · · Show · Open on Twitter

@RealtimeAI @krazyander @ToKTeacher @DoqxaScott

You can tell an explanation is a hard to vary if you try to change parts of it and you end up diminishing its ability to fulfill its purpose. I.e. an explanation is hard to vary vis-a-vis a problem it purports to solve. Pick any theory and try changing parts; if difficult, h2v.

I guess that the flaws you mention are generally the result of irrational memes and/or bad explanations.

@dchackethal · · Show · Open on Twitter

@mortimerSeth

In order:

Not generally. A chemistry lab may blow up during an experiment or something, but that’s an exception. Extinction of ideas is fundamentally non violent.

Those may all be drivers but can be overwritten. GPPS still susceptible to irrational memes.

Got it. Yes. Two possibilities that could make you correct in the first place:

1) if creativity is solely genetic and requisite knowledge of DNA created (so indirectly caused their own understanding)

2) understanding means replication so genes “understand” themselves in a way.

I watched it on the assumption that that's the one. I can see now how extinction can be seen as a constructor of future possibilities. Still unclear about your remark re DNA/RNA.

BoI p. 59 "[People] are 'universal constructors'".

p. 76 a constructor is "a device capable of causing other objects to undergo transformations without undergoing any net changes itself".

A problem is a conflict between theories. It doesn't do anything.

@dchackethal · · Show · Open on Twitter

@EvanOLeary

People are constructors. I don't think problems are.

Creativity is the only thing I know of capable of creating explanations. As David says in BoI, the creative program may be part genetic, part meme.

Nervous systems on their own don't create explanations. They're just hardware

Many scientists have the wrong PoS (empiricism, instrumentalism, positivism). That can lead them astray since there is no way to do science without PoS. But they all have one. And when they do create knowledge anyway, they’re doing something that’s the object of the study of PoS.

Or rather, their implementation is still “prescribed”, but their output is not exactly predictable. Input/output pairs can’t be reliably reproduced.

@dchackethal · · Show · Open on Twitter

@reasonisfun

I’m not sure. Isn’t creativity encoded in our genes and must therefore be programmable?

Not being able to relate output to input in a prescribed way just means the program isn’t pure. Eg Math.random(), Date.now(), etc. Those functions are impure but programmable.
