it does but you can run it a bunch of times with different clusters and pick the "best" one

(also its been more than a few years since ive done recommender systems but kmeans would def. not have been the first thing i reached for)

i think that impulse is backwards though, in that k-means is pretty good as a first "is this good enough?" check. in that it is one of those that is sure to get you *somewhere* without worrying about convergence or parameters (the k itself being a pretty intuitive thing)

There are clustering approaches that do not require you to specify the number of clusters before hand.


But that doesn't change that clustering posts and only showing you the ones in your bubble is stupid.

I grew up around Christianity in the American south and this is very true. The genius of Christianity is that it's a mind virus: In order to be a good Christian you have to convert others to Christianity. It's the GPL of religions.

the way i remember it is for recommender systems the thing to do is start with nmf-style factorizations, but again that was a while ago

otherwise agree in the absence of any problem knowledge kmeans is a good first start

see there's a kernel of insight here, derailed by the author's complete lack of broader understanding or context. an excellent example of the more tragic variety of HN comments

Won't someone please think about the poor startup founders and their $100 million dollar businesses

maneesh 17 hours ago [-]

Here's a thought experiment: You're a HN reader. You have had ideas to build a startup that can help the world solve a problem.
So you create it. You decide to fundraise, and that capital will help you succeed. You pay yourself a salary of $100,000/year, and put everything else into the company.

You raise $4 MM in a seed round, valuing your company at $20MM.

10-months later, your company is doubling growth YoY again, has a solid SAAS model, and low churn. You decide to raise again.

This time, you raise some more money for your company, and you're now valued at 70MM.

About a year later, you're growing just as fast -- but you see a new competitor is entering the ranks. It's time to scale even faster. So you go and raise again. In a fantastic series-B round, spread across TechCrunch and HN, you raise again, at a $200 MM valuation.

As the sole founder, you now own 50% of the company -- making you worth $100MM. Your salary has remained constant at $100,000/year though.

And then the wealth tax hits.

The new wealth tax says you're responsible to pay an annual tax of 2% on all assets over $50MM. Starting this year.

Which means that you, as a private founder with no liquid assets, are now responsible for $50MM * 2% = $1MM in taxes this year.

Even though your liquid income is $100,000, and you have barely that much in your bank account -- you need to come up with $1,000,000 in liquid cash this year. And since your valuation probably won't go down, it'll be at least that much, every year, for the rest of your life, until you shutter the company.

So you go and try to liquidate your shares. But unfortunately, it's not a public company --- and it's not that easy finding private secondary-market buyers willing to buy the half of the founder's entire stake.

So what do you do now?

As far as I can tell, this is how the wealth tax would work for startup founders.

also taxing illiquid wealth has a simple solution, you just put a lien on it for when it actually becomes sellable. if its value drops in the intervening time, fine, adjust it down. if it needs to get transferred for some other reason (death) then you just force it to be liquidated if nobody can pay the lien

the us constitution limits the sorts of taxes the federal government can impose in article i, section 9, clause 4: No Capitation, or other direct, Tax shall be laid, unless in Proportion to the Census or Enumeration herein before directed to be taken.

that was modified by the sixteenth amendment: The Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration.

taxes are considered direct if they're laid on people or property rather than transactions. there are scholars who think that the amendment was unnecessary, i think on the principle that income counts as a taxable transaction. that's the rule that allows inheritance taxes. but i don't see how you can stretch that to cover wealth; i'm in favor of a wealth tax, but i do think it probably needs an amendment. unless you can find a way to restrict it to be proportional to state population

These actions may look anti-competitive, but these companies are all foreign (China, South Korea, Japan). China does anti-competitive stuff to US companies all the time. I doubt there's any legal case for FB abusing monopoly powers based on this email. If anything, this is just very competent business decision making.

No, it's just an example. Probably a poor example. In reality I don't often meet vegans, but people get upset for all kinds of reasons / statements, most commonly for political ones which are to be avoided on HN (and real life) (and are quite easy to avoid, if you want to).
Another (non-political) one that comes up fairly often, is that I don't think it's reasonable to congratulate people when they decide to get married... it's a decision after all, nothing to do with achievement and/or luck (for most people I know at least, who aren't extremely lonely to the extent that finding anyone that tolerates them is an achievement... in which case, "congratulations" would be more in order), and if anything, they should be warned (as many marriages end in failure). But if you say that, you're the rear end in a top hat.
