NN computations -- in the main -- are high school Maths. Architectures are a topology governing chains of high school Maths. This is so much the case that the building blocks can neatly be expressed in a spreadsheet, which may or may not he

Set theory, mathematical logic and proof makes sense to learn early on. Maybe even after strong command of arithmetic. These things are very portable to thinking generally. They'll change the way you see in a way you can't unlearn

To my understanding, an LLM -- and similar models -- have a Markov chain equivalent. There is an old argument from philosophy that any mechanical interpretation of mind has no need for consciousness. Or conversely, that consciousness is not

I suggest searching job adverts by tech rather than title since OR tech is very specific to it.

If your aim is to evaluate an effect size of your treatment because you want to know whether it’s significant, you can’t do what the article advises.

I think this is what you need: https://github.com/facebookarchive/planout It’s just the bones of a factorial design framework for online experiments. It’s simple enough to copy/paste and roll yourself. Many have t

Yeah I think so, especially 2nd time around. You kind of have to refuse to think about your problem computationally; that’s really important when doing prolog I think, else you’ll end up with functional programming. I try to think about wha

I used Haskell to solve AoC 2022, and in the midst of it I read lots comparisons to Lisp, which in turn turned me off Lisp. E.g. "why calculating is better than scheming". I'd suppose this is because I have a strong bias to m

by usgroup 2y ago
I’ve been tempted in that direction too. Or using something like “Forth”. Both strike me as a “solve AoC with an abacus” style approaches, requiring bigger levels of problem understanding.

That sounds about right if your aim was to learn the language. I had the same experience with Prolog.

Just on this topic, would it be possible to make a whistle to do the same thing? I.e. crafted so it emits both ultrasound, and the audible counterpart which interferes with it to make the return audible? Perhaps it could be such that the ul

See here: https://www.youtube.com/watch?v=PD3Y1l8XyUw Another route would be to mix the ultrasound with another sound closer to the ear, then there is no need for an electronic ear at any point. The interference between sou

Has anyone used Datalog with Datomic in anger? If so, what are your thoughts about Logica, and how does the proposition differ in your experience?
81.
by usgroup 2y ago
I may be misremembering but I think that at the time, Logica was the work of one developer who happened to be at Google. I'm not sure that there was an institutional push to use this language, nor that it has significant adoption at Go
82.
by usgroup 2y ago
Its nice to see Logica has come on a bit. A year or two ago I tried to use this in production and it was very buggy. The basic selling point is a compositional query language, so that over-time one may have a library of re-usable components

I haven't read Hegel before, but I find the abstraction of something like "reason" as separate agent in itself, and then thinking about how its agency manifests a fun way of thinking. It is, I think, begging the question, wit

This is hard to do for products when they change over time. Eg if a product is upgraded and repaired, and if it has different versions and so on, it’s no longer a static distribution, and things get complicated.

Picking a specific definition of a word, expounding its consequences, and then referring to the colloquial usage of the word as a “myth” is just word-play as I said. Many do think of confounders in an experimental context as just those effe
