Hinge Loss function, still shows loss when values are matching

This is Hinge Loss equation So Assume that y = 0.5 and f(x) = 0.5 this means that both have the same value. i.e. no error and no loss but when I apply Hinge Loss I get this 1 - 0.5 * 0.5 = 1 - 0.25 = 0.75 How come values with zero error has loss?

Pure math courses most relevant towards "computational mathematics"?

Pure math courses most relevant towards "computational mathematics"? Since I've read that e.g. measure theory has some stuff that's not that applicable to (at least current) computation. I'm interested in understanding what pure math "courses" are…

Why use notations like $f(x)$ while explaining mathematical proofs or equations etc

If there is a variable "$x$" , and another is "$y$", and let's say I know the relation between them as $$x= y+1$$ Now, I want to use them in the explanation of some mathematical theory/proof/equation etc. Why a different notation called $f(x)$ (…

Why don't textbooks foreground marginally generalized theorems?

'Marginally generalized theorems' refers to theorems that were generalized so marginally that they can still be taught, and understood by the students, in the same course. Examples of theorems NOT marginally generalized: A skilled high-schooler…

For what values of b does the system have no solutions?

Help me please with system. It turned out this way: Multiply system 2 4x + by = 4 2bx + 2y = 4 The system has no solutions if: 4x + by ≠ 2bx + 2y x (4 - 2b) ≠ y (2 - b) 2x (2 - b) ≠ y (2 - b) For any b ≠ 2, the system will have only one…

Why don't we use the proper terminology for linear and affine?

Why do we call y = mx + b linear (in high school)? Why don't we call it affine? and linear what is actually linear $$f(x+y)=f(x)+f(y)$$ $$f(ax)=af(x)$$

Ways to improve automatic algebraic and arithmetic skills for exeperienced mathematicians.

I've been doing math for a long, long, long time. But I still make "stupid mistakes" such as dropping a minus sign, or forgetting to follow through with the chain rule in differentiation. I'm not even very good at basic arithmetic. I guess part of…
