Haha, that mission statement though! "empower all people," "help they deserve," "status quo is unacceptable," "they have had decades to find a solution to help the masses. They have failed," "fac

yeah, it's pretty annoying.

I hate this website. Trackpad scrolling is a workout. Spacebar is glitchy. How this design is any better than those clickfarming slideshows, I'll never understand.

just downvoting every one of my comments because you disagree with them? That's cool. 1) Just one example? Here: http://adslabs.org/adsabs/abs/2009PhDT.........4C/ 2) You are trying to find the global ma

I see you feel strongly about this. "The point of Metropolis-Hastings is to sample from a distribution when you do not know the partition function." That's one point, yes. The other is optimization. In which case I prefer the

Yeah, that's what I meant, the one particle bit. Frequently you'll see things along the lines of "we ran 10,000 MCMC iterations to find the solution" and my first thought is "that must be a lot of wasted cycles.&quo

Are you sure that Gibbs sampling isn't just the multivariate version of MH? What I'm saying is that convergence speed for MH is limited by the fact that guesses cannot communicate with each other... which doesn't matter when

Interesting choice... Seems like genetic algorithms, particle swarms etc. would be more attractive choices since they solve the same problem and are inherently parallelizable while Metropolis Hastings is almost 100 years old and designed f

This article seems to adequately describe the definition and obvious shortcomings of the word _thesis_; which is what a _masters_ student should be doing. A _doctoral_ student should be doing a _dissertation_. I'm not sure why so many

I don't really understand this article. The only example of industrial design and mechanical engineering being fused given in the article is the heat vent one where you took the vents off the top of the sweat-lodge shaped computer and

I'm just saying it takes about 30 seconds to explain the Metropolis-Hastings algorithm in plain english, and the wikipedia article is almost intentionally esoteric on the matter: http://en.wikipedia.org/wiki/Metrop

I found this article useful. What I was really hoping for was a layman's translation of the maths on wikipedia [ie. how to implement]. But this is a good jumping off point for figuring out which black box to use.

This solution is like trying to stir a pot of chili with an absinthe spoon. I'm not sure why there's this holy grail of "the unified master version of" whatever. Let me give an example. Say I write a paper on the shape o
