    As others have said, F# interesting language features are computation expressions, active patterns, units and type-providers. The library, platforms and ecosystem benefits are grav…

    I did not downvote (and you're clear now) but your post is not a relevant argument. The determinism that the SFWT is arguing against is that of certain hidden variable theories of …

    Wow, your idea is heading incredibly towards the same general direction as https://en.wikipedia.org/wiki/Sparse_distributed_memory described there. Excellent!

    One can view RNNs as a sort of generalization to markov chains. RNNs have the advantage of a memory, context tracking and are not limited to learning patterns of some specific leng…

    It's not a report, it's an almost 400 page book. He doesn't compare random energies, instead he looks at what, under reasonably generous conditions, the daily power budget each ene…

    Ah, I was confused for a second—I'd thought Markov was a library, but you meant the markov assumption—the topics are actually loosely related and orthogonal. Your excellent looking…

    This is a medical case study however, not a journalistic piece and you two are being at least a little bit unfair, I think. Since seizures and sudoku are not a common combination, …

    I agree that this wasn't done by the computer (did computers uncover the Higgs Boson?) but I also do not believe humans can take most of the credit: this was the result of a Man Ma…

    All the things you mentioned (plus e.g. bayesian networks and Restricted Boltzmann Machines) are examples of Graphical Models. You can roughly think of (linear chain) CRFs as being…

    Time reversibility exists in quantum mechanics because observables are self adjoint operators. Closed systems evolve unitarily. In simpler terms, you can think of it as the require…

    In nature, decentralized networks are more the norm. You find them in neural, gene, protein and metabolic networks. You find them in mycorrhizal networks of forests and in various …

    The short version is, if this is correct (which is exceedingly unlikely) then either quantum mechanics is wrong or whether P=NP has just become irrelevant. This is because, as Scot…

    I must very strongly disagree with you. ScienceDaily is as good an aggregator as you'll find. Sometimes, I'll even purposely seek out their write-ups on a topic because of one thin…

    SVMs were invented by a couple statisticians/mathematicians in the 60s. k-means also harkens back to the 60s, by mathematicians and control theorists. Decision Trees and Random for…

    There are actually 2 dates,the 24th and the 25th, in the data sample. You can do this in a manner that's both fairly comprehensible and succint, for arbitrary number of dates, usin…

    I might be mistaken, but it seems to me that the predictor should also be able to solve the halting problem. Additionally, if the entity to which the source-code is a descriptor fo…

    It depends, some people distinguish economic rent from economic profit by restricting it to economic profits that cannot be reduced to normal by competition in the long run. Some a…

    This uses a particular form of a fundamentally simple yet surprisingly powerful class of learning algorithms called regret minimization. CFR is interesting in an of itself as it sp…

    I do not think the manner in which you've apportioned blame is correct. The article is less technical than the press release yes, but the core of both remains the same. They both t…

    I'd characterize this differently and also, as a lot more interesting than that. understanding.pdf can be viewed as a sort of dual to this paper but they're not covering the same t…
