Check out this 156-page tome: https://arxiv.org/abs/2104.13478: "Geometric Deep Learning: Grids, Groups, Graphs, Geodesics, and Gauges"

The intro says that it "...serves a dual purpose: on one hand, it provides a common mathematical framework to study the most successful neural network architectures, such as CNNs, RNNs, GNNs, and Transformers. On the other hand, it gives a constructive procedure to incorporate prior physical knowledge into neural architectures and provide principled way to build future architectures yet to be invented."

Working all the way through that, besides relearning a lot of my undergrad EE math (some time in the previous century), I learned a whole new bunch of differential geometry that will help next time I open a General Relativity book for fun.


I have very little formal education in advanced maths, but I’m highly motivated to learn the math needed to understand AI. Should i take a stab at parsing through and trying to understand this paper (maybe even using AI to help, heh) or would that be counter-productive from the get-go and I'm better off spending my time following some structured courses in pre-requisite maths before trying to understand these research papers?

Thank you for sharing this paper!


You might take a course on linear-algebra, at K.A. for example:

https://www.khanacademy.org/math/linear-algebra

And any prereqs you need. I also find the math-is-fun site to be excellent when I need to brush up on something from long ago and want a concise explanation. i.e. A 10 minute review, more than a few pithy sentences, yet less than a dozen-hour diatribe.

Thank you for sharing the paper!

The link is broken though and you may want to remove the `:` at the end.


Methinks Zawinski's Law of Software Envelopment finds some empirical support here.


Oh FFS why is print-vs-debug being debated as either/or? Both can be valuable, depending on the circumstances. It's clearly both/and.


it's not presented as either-or in the article: i talk about how debuggers AND logging are both important tools


Well dang, we are not restricted to git as the only place we can put historical metadata. You know, discursive comments, for starters?


I once worked with a company that provided IM services to hyper competitive, testosterone poisoned options traders. On the first fine trading day of a January new year, our IM provider rolled out an incompatible "upgrade" to some DLL that we (our software, hence our customers) relied on, that broke our service. Our customers, ahem, let their displeasure be known.

Another developer and I were tasked with fixing it. The Customer Service manager (although one of the most conniving political-destructive assholes I have ever not-quite worked with), actually carried a crap umbrella. Instead of constantly flaming us with how many millions of dollars our outage was costing every minute, he held up that umbrella and diverted the crap. His forbearance let us focus. He discretely approached every 20 minutes, toes not quite into entering office, calmly inquiring how it was going. In just over an hour (between his visits 3 and 4), Nate and I had the diagnosis, the fix, and had rolled it out to production, to the relief of pension funds worldwide.

As much as I dislike the memory of that manager to this day, I praise his wisdom every chance I get.


Yeah, basically the oil companies pumping up fossil fuel to burn, but we get a single use of it as plastic before it goes to the incinerator.


A little stoichometry suggests that, ignoring oxygen, hydrogen, and energy input, the cited worldwide market for C2H4 would be satisfied by just about 1 gigaton of CO2. So if "we need to process gigatons of CO2 annually", that ethylene's gonna pile up.


Earth escape velocity is 11.1 km/s, which is Mach 32 at sea level. They have some more engineering to do, maybe even invent something better than carbon fibers.

OK, but I'd rather prevent/cure the dementia.


Is no one going to tell him? Should we?
