I think brk was just saying that everyone in priority will have room for their bags. Without priority boarding, they would have to fight with everyone else.

What I mean is that, if just doing regular Newton, I'm not sure I've ever seen an example using the interface you show. I think that the vast majority of Newton's method implementations pass H rather than H^-1, and get the s

Is it typical to interface to Newton's method via a function that computes the inverse Hessian? I've never seen that. Typically, people claim it is numerically unstable to explicitly invert the Hessian, and that it would be bett

Doesn't seem to work in firefox? (The search bar keeps getting activated.) I think I have the "automatically search on typing" option selected though.

Great questions! I can answer a few of them. - Yes, you can get stick in a local maximum. However, see the k-means++ algorithm for a clever initialization scheme that gets you within a good constant factor of the global maximum. - The bes

I have to disagree. The potential downside for a flaw in the new bill could be rather catastrophic damage to the economy. The downside of a failure with the Mars rover is that the rover just doesn't work. Thus, it makes sense to be

I totally agree-- the problem with reviews isn't technological. Reviewers fundamentally need better incentives to do a good job, which I'm not sure how to do.

There are lots of things you might consider, that would be impossible with snail mail. For example, the reviewers might be able to send regular emails with questions to the authors, or the authors might be able to constantly update the pap

Actually, it takes real effort to make GCC not completely optimize-away this kind of stuff for C: https://github.com/JuliaLang/julia/issues/1325

There is evidence of a bunch of mild benefits (and also mild risks). I'd currently say it looks like a small net benefit, but with a confidence interval that would include negative territory. In general, it seems reasonable to drink coffe

If the current penalties remained in place for smoke-driving there would be no increased incentive to drive while stoned. In general, I think the problems you bring up are perfectly valid, but I see no fundamental reason society should dea

Well, the confidence intervals are right there on the charts, and look pretty damn significant to me...

If you are worried about climate change, it seems like our problem in the future might not be running out of fossil fuels-- it will be having entirely too much, making renewables very expensive in comparison.

There is no reason to think that prices elsewhere will get worse . If they could get away with charging higher prices in non-metro areas now, they would do it already. It is likely, however, that non-metro areas will fail to see the pric

What, really? I've never had someone in front of me use the space beneath their seat. That's my space! (I'm also 6'2" and only bring a small carry-on because I need that space for legs.)

In my experience, the number of applications submitted is actually somewhat low compared to most recently graduated PhDs these days.

The central limit theorem only applies when random variables are combined linearly . I see no reason to suspect that this is the case with random inputs for testing. (Most functions are nonlinear!)

Wow-- apparently Mergesort can be implemented in-place!?

Interesting. Are you saying that the technology for thorium reactors wouldn't be so closely related to weapons technology?

The issue is that it is nearly impossible to detect "the same". Imagine the sample size required to differentiate between .5 and .500000001. Now, technically speaking, sure-- with any effect (however small) in the infinite data limit a di

This error builds on a simpler, even more common one (at least among students): Suppose you have just one treatment (A), and you find that A has no statistically significant effect. This does not show that A has no effect, or that A's ef

Well, since Steam only stores the salted PW hashes, it doesn't seem like that would allow them to compromise your facebook account.

I don't see why not. Different classifiers have different bias/variance characteristics. If you want to increase variance and decrease bias, than boost your classifier. (This is why boosting is usually applied to simple classifiers.) Bu

In a case like this, perhaps a perceptron?

I think it's more that machine learning builds off of earlier work in statistics. If I remember correctly, that class discusses lots of other things that are used in ML but were invented elsewhere (gradient descent, maximum likelihood, mat

I think we should note that logistic regression has been around forever, and should probably be considered property of "statistics", not "machine learning".
