    Gary Marcus Retweeted Joscha Bach

    Of course, evolution is statistical. But as I wrote in AlphaGo critique: blurring distinction between evolution & learning blurs causal mechanisms. May as well call it all change and lump rock formation with classical conditioning; key question is whether you need strong priors.https://twitter.com/plinz/status/968490295968063488 …

    Gary Marcus added,

    Joscha Bach @Plinz
    @GaryMarcus' nativist argument against statistical learning AI seems to rest on the premise that evolution is fundamentally different from a statistical learning paradigm. This is false (evolution IS a form of statistical learning), but I am grateful that Gary makes that point.

        As you can see in the comments you are confusing the audience. But to your argument: why do you think that the priors can be found by organic evolution but not by any other statistical search method?

        Calling evolution 'statistical' seems rather instrumentalist. To make predictions we use statistical models and methods, but to explain it, they are not required.

        And where the priors come from

        Seem clear to me there is an effort to rationalize AI disconnected from their human creators and human data generators. To make AI to be something it never will be. Why? Bow down to the stone image ruler over you but ignore the humans behind the biased curtain controlling the AI.

        Do you think evolutionary algorithms learn things that non-evolutionary algorithms can’t? That seems important for nature/nature debate

        I think the causal distinction doesn't differentiate learning from non-learning (taking "learning", I think uncontroversially, to be persistent behavioural changes due to environmental input). Difference is maybe timescale related (or maybe individual vs population level?)...

        Replying to @GaryMarcus

        "May as well call it all change" -- I wish to pause an think about it: Fundamental physics does not know where it ends, and biology or psychology begins. It all always is a physical dynamics of the universe, in which, for whatever complex reasons, some modes grow stronger.

        Replying to @generuso @GaryMarcus

        The peculiar thing, is, of course, how simple this unfathomably complex dynamics can become when coarse grained -- not only do atoms always interact in a certain way with other atoms, but so do enormous lumps of atoms that are cats, etc.
