better remove all the Disney-based Alice in Wonderland character intellectual property from the book.

I was just thinking that's "cease and desist" bait right there.

Alice in Wonderland (the book) is in the public domain. The old Disney movie is still in copyright, and the cover image does look very much like it's from the movie, but that character design is from John Tenniel's illustrations which are also in the public domain.

Before the recent AI boom, I was mystified by the possibility of AI and emulating humans (in no small part thanks to works of fiction showing AI powered androids). Then I created and trained some neural networks. Smaller ones, doing much of nothing special. That was enough to break the mysticism. To realize it was just multiplying matrices. Training them was a bit more advanced, but still applied mathematics. Only re…

Exactly, the people who are derisive of those who consider ML models to exhibit glimmers of true intelligence because it's only matrix multiplications always amuse me. It's like they don't even realize the contradiction in holding the position that seemingly complex and intelligent outward behaviour should not be used as an indication of actual complexity and intelligence.

If you study this historically you will see that every generation thinks they have the mechanism to explain brains (gear systems, analog control/cybernetics, perceptrons).

My conclusion is we tend to overestimate our understanding and the power of our inventions.

I feel like this statement is both obvious after spending a few minutes working with neural networks and completely useless in helping you build better neural networks. It's kind of like saying, "Stripped of anything else, works of literature are compositions of words"

Well, I’d argue that could also be a bit enlightening. It’s like taking a moment to appreciate that forests are composed of single trees. It takes a certain level of insight to appreciate systems at various depths.

The difference is that we now actually have a proof of computational power and computational universality.

Ya so far this is the best introduction to neural networks from first principles that I've seen. Quickly skimming the draft pdf at https://arxiv.org/pdf/2404.17625 I can grok it instantly, because it's written in familiar academic language instead of gobbledygook. Anyone with an undergrad math education in engineering, computer science, etc or a self-taught equivalent understanding of differential equations should be…

Thank you for the summary, and thanks to the OP/author of the book.

I started self-studying programming some time ago, then pivoted to AI/ML and (understandably) ended up mostly studying math, these resources are a boon to my folk.

Analog circuits have the same computational power. Piecewise linear functions have the same computational universality.

The character design is. The image, however, is clearly Disney flavoured if not traced directly.

His version, for example, does not have the distinctive bow. The art style is also completely different.

Except we didn't know any of that, nor did know how to construct physical analogs in order to achieve universal computation. At best, we had limited task-specific computation, like clocks and planetary motion.
