    is this really worth a nature paper??
  • Luzi Bergamin on 19 Jan 10
     
    Funny to read this question exactly from you, the all and ever fan of anything linked to bio :-) I have read worse papers in nature and in addition it's just "Nature physics", viz. "Nature garbage." Could be that they don't find enough really good stuff to publish in all their topical clones of Nature.

    Dario - perhaps worth giving a look to be up-to-date... There's even an article "Improving Classical and Decentralized Differential Evolution with New Mutation Operator and Population Topologies". They quote our CEC paper, but not the ParCo.

    Don't know if you have full text access, so here goes the quote: "Recently, Izzo et al. designed in [27] a heterogeneous asynchronous island model for DE. They considered five islands and five DE strategies (DE/best/1/exp, DE/rand/1/exp, DE/rand-to-best/1/exp, DE/best/2/exp, and DE/rand/2/exp), and studied five distributed DEs using the same DE strategy in all the islands, and a heterogeneous model with one different DE strategy in every island. As a result, the heterogeneous model is not outstanding, but performs as well as the others."

    Isn't it a bit a paper-killing quote?
  • Ma Ru on 03 Mar 11
     
    :) It's in the context of a review of the work that's been done about DE with island model in general, they don't evaluate. Pity they didn't refer to the ParCo article on topologies, as it was a bit more extensive and more focused on the method (as they do in the article) rather than on the problem (as was our CEC paper, if I recall well).

    they used names of scientists and research centres without these actually knowing about their involvement it seems.... I am wondering what they actually reported back in terms of results? randomly generated papers? Christos?

    Probably some bored project officer "accepted" the deliverables as reasonable? What worries me is the last paragraph by the Committee on Industry and Research (Space is in there..., all RTD is there...) Are we going to simplify procedures or tighten more??? Because there is a lot of talk about simplification in FP8: which is not well received by Parliament/Council and co...
  • Luzi Bergamin on 18 Jun 11
     
    Hopefully I'm wrong, but I'm very pessimistic. I guess they will impose even more control, ask for even more detailed description of the results that will be delivered and concentrate even more on project funding instead of funding open research.

    Amazing how some guys from some other university also did pretty much the same thing (although they didn't use the bidirectional stuff) and published it just last month. Just goes to show you can dump pretty much anything into an RNN and train it for long enough and it'll produce magic. http://arxiv.org/pdf/1410.1090v1.pdf

    Seems like quite the trend. And the fact that google still tries to use LSTMs is even more surprising.

    LSTMs: that was also the first thing in the paper that caught my attention! :) I hadn't seen them in the wild in years... My oversight most likely. The paper seems to be getting ~100 citations a year. Someone's using them.

    There are a few papers on them. Though you have to be lucky to get them to work. The backprop is horrendous.

    Actually Sante and me just reviewed their paper. Although (some of) the scientists in the paper seem to have good track records their experimental techniques are by far not the best to determine the excess amount of energy produced. Even though their methods may introduce fairly large errors they would not be able to negate the cited power output - so they either are super-sloppy (i.e. they lie) or there is TRULY new physics involved... A big problem is that they are basically verifying somebody else's experiment - however because this guy is paranoid he does not tell them exactly what he did. In fact they went to his lab and used a setup that HE put together. All they do is do a measurement on it and it seems like they try to be thorough. There is quite a chance that the guy behind it all (Rossi) is setting them up - personally I would think >95%. However, the implications of this being new physics are so big that I think further research should be conducted.
  • LeopoldS on 24 May 13
     
    I just answered something very similar to Franco, except the conclusions: I don't think that there is a good reason for us or anybody else in ESA to get involved at this stage.
  • johannessimon81 on 24 May 13
     
    I agree - if this device would work it there would be other interest groups (like the energy sector) with a much more concrete stake in the technology.

    How many shapes can be obtained by folding a paper and applying just one straight cut? You'll be surprised...
  • johannessimon81 on 30 May 13
     
    "The theorem is that every pattern (plane graph) of straight-line cuts can be made by folding and one complete straight cut. Thus it is possible to make single polygons (possibly nonconvex), multiple disjoint polygons, nested polygons, adjoining polygons, and even floating line segments and points." - So the you can cut any assembly of polygons but not a single curved edge (with a finite number of folds (points don't count)): useless. :-P
