financial markets also work this way — the current market price is for a limited quantity and if you trade the price will move. moreover people go to great lengths to try to avoid trading with winners. there have been cases where people’s b

this pattern is a pretty defensible way to run a sports book. obviously you don’t want to accept large bets from someone who is doing arbitrage or consistently has inside information. any business with variable prices works this way, if som

like a lot of libertarian experiments in the US, we seem to have done it in the worst possible way. implementation matters. if it had been up to me, sports gambling should have been restricted to physical locations, and marketing prohibited

if you have a license for a good fast solver already for some reason, it can be very effective to reduce some NP-hard problems to integer programming. also, one interesting application related to data science is to embed a machine learning

it got started with massive overprescription of opioids in the 2000s, then the government belatedly cracked down on that, and a lot of people who got addicted switched to street drugs, which is when the crisis became obvious to the public.

JuMP is comparably good I think. People reasonably don’t want to add a new language to their stack. But if you’re just formulating MPs it’s as nice as anything, free, and you have a well designed modern programming language if you need it.

Arc is a great product, it's the nicest web browser to use, you can tell these people are really good at their jobs in many respects (though apparently not security?!?). probably a lot of investors saw that too and are willing to fund

i'm rooting for them to succeed, but if the concern is security, switching your daily driver browser to a brand-new browser that's still in alpha is unfortunately not a good idea.

but nobody has to pick between “the worst manifestation of counterculture” and “traditionalist monarchism”. you can have a whole range of normal political views instead.

it's good to hear that my impressions weren't based on nothing. personally i don't like when a translation works like this, I think it's better to try to replicate the literary effect in the target language. (For example

the problem is for any given Russian novel, there are often other translations from the 1960s-1990s which use sufficiently modern language. maybe these are better than P&V or maybe not (in some cases yes to my taste), but good luck find

the P&V translations always give me the sensation of American actors speaking in mock Russian accents, like in the Hunt for Red October. I don't really like them for this reason. I imagine they have merits which I am not equipped t

there is concern about tacit collusion if all the airlines start using the same pricing algorithms based on the same historical data. it doesn't even take a very smart pricing strategy for them to naturally learn to collude with each o

by currymj 2y ago
Algorithmic pricing that learns to tacitly collude is a hot area of study in computer science and economics. For example, if you train simple online learning algorithms to adjust prices, sometimes they can learn to keep prices high or to ta

it's a tough problem. there are various schemes for estimating mutual information from samples. if you do that and mutual information is very close to zero, then I guess you can claim the two rvs are independent. But these estimators a

Rigorous causal inference methods are just now starting to diffuse into the undergraduate curriculum, after gradually becoming part of the mainstream in a lot of social science fields. But this is just happening. Judea Pearl is in some resp

This is a separate issue and also a good point. Correlation sometimes means “Pearson’s correlation coefficient” and sometimes means “anything but completely independent” and it’s often unclear. In this context I mean the latter.

Rule 2 (“causation creates correlation”) would be strongly disputed by a lot of people. It relies on the assumption of “faithfulness” which is not discussed until the bottom of the article. This is a very innocent sounding assumption but it

the corporate descendants of Cray, now owned by HPE, still win the contracts to build a lot of supercomputers. but it's not like the days of Seymour Cray himself, hand-designing every aspect of the system. They use off-the-shelf parts

no, CFR is mainly just a way of computing Nash equilibria and (although in some sense it is an online, iterative algorithm) would typically be used to precompute Nash strategies, not update them in real time. real poker playing systems augm
