While I can imagine that neural networks are useful in predicting rainfalls or precipitations, I don’t see how they are suitable for some tasks, such as the forecasting of typhoon paths. A neural network is basically a function interpolatio

Thanks for the link. The article offers some really useful advices.

Apparently, the author is wrong. See "Does Earth really have two high-tide bulges on opposite sides?" ( https://physics.stackexchange.com/q/121830 ) on Physics StackExchange.

One problem of KaTeX is that its feature set is too small. It doesn't even support some very basic commands such as \overrightarrow.

The paper has only seven pages, but the actual proof is even shorter --- it spans from p.3 to p.5. So, it's a three-page proof. Really well done.

Agree. Feng-hsiung Hsu, the chief designer of Deep Blue, the chess machine that beat Kasparov, once gave a talk at my university. I didn't go to the talk, but in the abstract, he stated clearly that he didn't think Deep Blue is AI

Adding a constant diagonal matrix indeed would not affect the equilibrium distribution. Mathematically, if the original transition matrix is A and you add a multiple of the identity matrix to it, then after normalisation by row sums, the

Agree. Depending on what one wants to measure, giving every sample equal weight can be potentially wrong.

If you mean to account for the larger variances of rarer events, that would be difficult. Perhaps some bootstrap sampling methods may help, but we need a true statistician here.

The research methodology in this blog post is fundamentally flawed. The author only counts how many people move from X to Y, but he doesn't count how many of them do not move at all. The whole diagonal of his (sample) transition matrix

Yes. The effect of having a coarser partition around a mesh point is countered by the effect of a higher frequency of hitting that partition. This actually is the essence of importance sampling. For the purposes of numerical integration, as

Would you please elaborate? I think almost all mathematicians use classical logic rather than intuitionistic logic.

I think The Guardian and FT are not bad at all. I don't intend to start an argument, but I'm curious to know which newspapers (in other countries) in your opinion are good.

"A survey was sent out to 1234 physicists affiliated to 8 different universities. 149 responded to the questions..." The sample looks too biased (just 8 different universities) and the response rate is low (149 out of 1234 physici

Would anyone please tell me which of Linode, DigitalOcean and Vultr have cost ceilings? I looked at their pricing pages but couldn't figure out. They all claim that they have monthly billing caps for the hourly rates, but meanwhile, bo

Looks cool. The hand-drawn graphics give the game a unique style which I find very attractive.

While I agree with the author's points, I don't think we need another post to praise Vue.js. The merits of Vue.js are quite evident, even if you have watched just a few minutes of some video tutorials ( https://laracasts

Perhaps I am dumb, but after reading the article twice, I still don't understand what the author is talking about. I'm not saying that Javascript is an easy language (it may or may not be). I just don't get the author's

Hmm, since the appearances of low-quality answers on SO are so different from the others, I usually end up moving the mouse over them impulsively to read them. Had SO not greyed out such postings, I would have simply ignored them and saved

No, you couldn't. Suppose $f(x)$ decays like $O(e^{-x})$ and $a_0$ is the constant term in its power series expansion. Then $g(x)=f(x)-a_0$ decays like $O(e^{-x}$ if and only if $f-g$ decays like $O(e^{-x})$, which in turn is equivalen

I think some of the author's criticisms are misplaced. Long functions — Yes, functions in scientific programming tend to be longer than your usual ones, but that's often because they cannot be split into smaller functions that are

You are misreading the ruling. It doesn't say that Itu Aba (Taiping Island) isn't an island. What it says is that Itu Aba is a maritime feature that "cannot sustain human habitation or an economic life of their own". Eve

Hmm, isn't this an infinite loop? i and j are not incremented. I'm surprised that the program can end in finite time.

> Elixir also follows the Ruby philosophy of hiding as much behind the syntax as possible, whereas Elm tends to be very explicit. This is not true. While Elixir may not make things as explicit as Elm (I don't know Elm well enough to
