I'm seeking recommendations for explainable regression models for tabular data. I'm looking for approaches that offer a balance between complexity and interpretability – something more sophisticated than simple linear regression or decision trees. While I'm aware of popular options like SHAP, LIM...

Are all coherent inferences deductive, inductive or abductive? If I justify a belief (to some degree) to myself, and it is not the best explanation, I am not deducing it from any premise, and it is not an induction from something occurring to it occurring again, then is my justification a sham? W...

I've created a method which allows to run tasks where results might not be fully computed but still are considered valid.

I remember an alternate story from a while ago where the Soviet Union promoted a centralized networked computing model that proved more effective than the decentralized Western version. As I recall it was written from a somewhat triumphalist POV that presumed the West was structurally incapable o...

As far as I know, “same” and “identical” have identical meaning. Why is one used with “the” and one without “the”? I can argue that “same” should always have “the”: When thing 2 is the same as thing 1, they are actually just one thing. So only one thing is the same as thing 1, i. e. thing 1. So “...

So ive received an academic misconduct (yes my fault) which will result in an F in the course and a term suspension.

I used to own the first book of what I think was a duology. I'm pretty sure I bought it, in England, in the late seventies, possibly early eighties, and it was recent at that time, so not a reprint of an old book. I think the title of each book was a single word, or name, possibly Japanese. Most ...

I read on https://dj.studio/blog/camelot-wheel: The Camelot Wheel is a modern system to help DJs navigate the musical keys of their music.

I have this differential equation that models a causal LTI system: $$ \ddot{v}(t) - \dot{v}(t) - 2v(t) = \ddot{u}(t) + 2\dot{u}(t) + u(t) $$ I was asked to find the impulse response both by using Laplace transform and by solving the ODE. The first method is quite simple: set initial conditions to...

Suppose that $(z_n) \subset \mathbb C$ is a sequence (repetitions allowed) such that $$ F(z) = \prod_n \left ( 1-\frac{z}{z_n} \right ) $$ defines an entire function of exponential type, that is, $|F(z)| \leq ae^{b|z|}$ for $a,b > 0$. Further, let $(p_n) \subseteq \mathbb C$ be a bounded sequence...

Let $G$ be a group. A subgroup $H$ of $G$ is said to be fully invariant if for every endomorphism $\phi $ of $G$, we have $\phi(H) \subseteq H$. For a finitely generated residually finite group $G$, let $N$ be the intersection of all finite index fully invariant subgroup of $G$. It seems in all t...

One of the isomorphism theorems states $(HN) \ / \ N \cong H \ / \ (H\cap N)$. I am confused about the first part $(HN) \ / \ N$, and whether it is equivalent to $H \ / \ N$. Every element in $HN$ is $hn$ for some $h \in H, n \in N$. So then every coset in $(HN) \ / \ N$ can be expressed as $\{hn...

In discussions of D&D, especially discussing older editions, the term Vancian sometimes comes up: "Vancian" spellcasting, "Vancian" magic system. But this word doesn't actually seem to exist in any Dungeons & Dragons rulebooks, in any edition, old or new. The word is apparently just common knowle...

In my previous question I mentioned a character with the ability to control electricity.

I recall reading in English a short story about the extraction of a German (or Russian) scientist defector from the Iron Curtain in a fiction published in a magazine somewhere in the early 1970s (it was probably Asimov's or F & SF). The narrative took place during the Cold War. A woman assisted a...

This cribbage board is a mystery I am trying to solve. It has an aircraft flanked by linked flags - they look like the Union Jack and the former Canadian Flag - and a maple leaf. It suggests that it's a commemoration of a 30's/40's aviation link between those countries. I have asked the ques...
