    For the latter, a dictionary?

    And wave functions collapse only upon measurement...clever lazy initialization

    You can just have the ELO score, which is the basis for assigning dan levels: http://www.goratings.org/

    These CPU/GPUs are doing very inefficient digital simulations of analogue processes. If anything, human brain has significantly more 'processing power' than Alpha Go when you restr…

    It is typical for ML systems to surpass human performance while having very different characteristics in what it got right/wrong. For example in ImageNet, DCNN got a lot of points …

    Seconded. Another extreme example would be human brains, which I don't think we understand enough for it to be "accountable" in any mathematical bounds, yet we trust them to make c…

    Brains don't do FLOPS. It is a completely different type of "calculation". Computational benchmarks are only directly comparable when the representations of input and output are th…

    >Whilst it is unable to assign one symbol with multiple nouns, I think these are more engineering issues than anything. The overall architecture of NELL can be made smarter with ho…

    Numerical Analysis is too broad for this topic. The precise category should be: https://en.wikipedia.org/wiki/Mathematical_optimization The hierarchy of topics in this area: http:/…

    With uncertainty you just change your objective function to an evaluation function of any possible scenario scaled with its probability. It doesn't change how optimization works. A…

    Ah, sorry no. I'm just interested in AI in general and constrained optimization has been the what I found to be the most general model for solving and giving insights into AI probl…

    The so-called reason by analogy is just gradient descent to approach local optima in optmization. The "by first principle" is just providing an approximate (ideally convex) model a…

    This reminds me of the difference between pointers and actual values - it is more efficient for you to memorize where the detailed and possibly complex information can be found. Me…

    People in China are well-informed about all these companies overseas and often question about the Chinese version's originality. Companies like Amazon do have their own branch in C…
