Multiclass Classification and SVM

No.13445080 ViewReplyOriginalReport
I've been reading on SVM and I learned that it doesn't support natively multiclass classification but it usually uses two different methods,
-one-vs-all, that generate a classifier for each class against the rest,
-one-vs-one, that considers classes two by two and makes a classifier for each pair.
What I'm confused about is the criteria that it's used to assign the class once the results of all the classifiers are out. I can understand taking a majority vote in the OvO case (although I have no idea what it's done in case of a draw) but I have no idea what's the solution for OvA.
Pic related is what causes me most issue since elements in the outside corners will get two matches (which is a draw again) but an element in the center triangle wouldn't be a match for any of the classifiers. In this case does SVM reject the element as not belonging to any of the classes or is there a catch?

I was hired as a data analyst by a company and now after three weeks I have solved all their problems by creating a few fairly simple dynamic tables on excel.
How do I keep pretending that they still need me so I don't lose my fucking job?

What's a good method for forcing myself to constrain my calculations on the page?

I've always taken up a luxurious amount of space to do my maths, and I tended to keep things very disorganized. It's finally starting to bite me in the ass as I move on to higher maths.

Any anons overcome this problem?

What am I missing here? Did Heisenberg get it right?

https://en.wikipedia.org/wiki/Kim_Peek
Assuming Kim Peek's IQ without his savant syndrome would have been 100, with his functional IQ as a savant being 87, and taking into account that a similar thing happens to downies (there are smart downies, but were they not to be downies, they're IQ would be 30 points higher), then we can conclude that if someone like Von Neumann were to have been born with savant syndrome, we would have had the greatest human computer in history: IQ down from +200 to 180, but acquiring the ability to multiprocess different streams of thought, eidetic memory, hyper fast processing power, and instant recall.

Have you made peace with the fact that you are too stupid and ignornat to have a say on anything?

You are no different from these people, you have no knoweledge, no understanding, all you have is trivia. And worst you are not ashamed of your ignorance, you have no qualms about stating that "the Universe' expands" but when push comes to shove you couldn't derive the Einestein field equations to actually prove your claim. And even if you could derive said equations you couldn't interpret them.
All your knoweledge boils down to "well I know this is true becasue other people told me it's true".

How long is this motherfucker going to last?
I don't want to make this yet another pro-vax vs. anti-vax thread. Assume people have made up their minds either way. Realistically, when can we stop hearing about this motherfucker?
