what about one with a falsified result?
fwiw I think convexity and understanding are relatively orthogonal, but how could one employ the former without the latter? However the author's position seems to be more that gaming systems works better than exploring their contexts. Sometimes you might make more money in less time, but the money is all you'll get out of it. In practice, maybe understanding and convex payoff functions are both useful at different scales.

Brouwer's career suffered as a consequence of his disagreements with Hilbert.

Re:Ask HN: Is neuroscience-inspired machine learning the next big thing?
on Thursday November 22, 2018 @10:37AM (#18510568)
I've come to think of machine learning as an engineering approach for building more scalable statistical systems. Computational neuroscience seems like it does more math modeling for understanding of brain function, but still might use machine learning methods as part of its research.
Also, good is subjective, and we don't have wetware in our engineering toolchain anyway. Loosely coupled metaphors seem to be popular and effective due to ambiguities like this.

Meaning is a process of its own creation, not a measuring stick. Often when people speak of meaning as though it were quantitative, they usually are referring to how much they help other people. Meaning is also interactive, it rarely happens in total isolation. If everyone around is constantly conflating meaning with monetary success, it's easy to feel confused and despair. Don't blame money, but rather look for bits of beauty in life and share them with people you care for. At least that's what seems to work for me

Re:Working from home may hurt your career
on Wednesday April 19, 2017 @10:59AM (#14148164)
working from home entails a personal responsibility for effectively scheduling your time. having a separate space from "normal" household activities can really help staying focused and avoiding overwork / burnout.
over time, the worst part of working from home is lack of eye contact. engaging with others outside of home can help, but there's still an awkward quality to getting to know people without seeing their reactions

"smart" is often interpreted as a measure of skills with symbol systems, rather than any general capacity to cultivate understanding. it wasn't that long ago that this sort of reactionary logic was used to justify enslaving large populations of humans. bias borne from the relative locality of individual existence is hardly a solved problem for humanity. In future I'd hope for greater understanding and less disgust

Speed reading techniques often try to break written word streams down into visual chunks and let the wetware do the rest. Unsurprisingly, results vary widely. Ironically though, this sounds a bit like a very high level description of segmentation as in computer vision
