    The similarity between writing & training a neural net is striking. Start with random weights (AKA a bad first draft), and apply gradient descent until it plateaus / you can't bear it any more...

        It’s not gradient descent unless you send it other people, get feedback and iterate. And even then it’s a very weak analogy. Rewriting a draft is more akin to code refactoring. You realize the intent you initially had and you figure out how to express it better on every edit.

        For you, maybe. For me, it's much more like gradient descent.

        Oscar Wilde said that writing was easy. You just sit at a typewriter and bleed.

        That’s pretty much all iterative processes.

        Both are creative/iterative processes that spawn knowledge with increasingly hard to vary explanations and are at the beginning of infinity? Random weights = “conjecture” and gradient descent = “criticism”. So really both can be thought of as science?@DavidDeutschOxf

        What I like most about this analogy is the emphasis that the first stage of writing/coding/creating is very often just random initialisation. One of my most treasured realisations - though it took me years...
