Firmware doesn't update as often though so it'd have to be static wear-leveling. I'm not sure of the safety of doing this with firmware files though - could it actually decrease the life expectancy by moving critical blocks m

I'd guess it's for people in the second camp (practical) who are just trying to satisfy their intellectual curiosity or want an intro to the math behind it all. I agree with your assessment that's it doesn't have much pr

I don't believe liquidity necessarily has anything to do with efficiency, but more liquidity can never hurt. Even if the price of every stock right now is 100x what it should be, I still want lower spreads. And to address your concerns

Depends on which null hypothesis you're testing. He told us that he rarely had a down day, and based on Bitcoin's volatility I'd say it's reasonable to assume the probability of it going up or down on any given day is a

You have to make some basic assumptions to do any statistical inference, because if you don't then literally anything can be explained by luck. For example, even if the author did a follow-up post (which I'd love to see as well!)

Through hypothesis testing you can estimate the probability that this was due to luck is very low. Assuming that a monkey would have a 50% chance of profiting on a day, the chance of going a month without a losing day is less than 1 in a bi

Same. I don't think history will look kindly upon someone who "quit for losing" while other professional Go players keep playing. Just imagine if Garry Kasparov quit after losing to Deep Blue, he would be ridiculed today by t

That's a really oversimplified view. The truth is beyond a certain point no amount of "theorizing" is enough to overcome the sheer computational power of programs. AlphaZero just took advantage of recent advances in neural ne

I feel like posting this on HN is preaching to the choir. Anyone with an ounce of critical thinking skills is not going to take claims that "the world is ending" at face value, nor dismiss evidence of climate change. On the other

They re-use the same initialization, so it appears that the initial weights are inherently coupled with the nonzero structure.

I've always wondered this and can never find a satisfactory answer online. You'd think that if ReLU works then LASSO shouldn't present any problems either right? In addition L2 tends to discourage sparsity by spreading out th

That's intuitive but doesn't support the result of the lucky subnetwork (once found and re-initialized) training faster and outperforming the original.

That's nifty! I spent a while trying to figure out how it worked before realizing it's a Voronoi diagram. Simple yet beautiful.

On a 30-year time horizon it would be more reasonable to use the S&P as a baseline as you can increase your short-term risk appetite. Since Nov 1989 that's a 15.82x return (incl. dividends)

You can teach them to do it yourself by bouncing back from Quora and going to another result. Perhaps it'll also encourage Quora to remove their paywall from search engine referrers, as many news sites have done.

That might very well be true for the repeat customers and people who buy clothing, but I doubt anybody wants a 2TB USB stick that starts overwriting itself after 100MB.
