Boosted decision trees account for >50% of all Kaggle winners. That is the real surprise, since people rarely talk about boosted decision trees.

Of course, this all breaks down when you have a cartel :) I recall in one of the major prisoners dilemma tournaments, the winning entry was actually a coalition of users who would use the first few moves to establish a code for membership i

From my limited understanding, a smart contract essentially runs in a VM with a dedicated memory space that is unique to that contract (and copied along with the contract). However, there is a limited ability for it to interact with other c

This project alone is more convincing that the entire linked article. Needless to say, I love it!

Why would you think it has little to teach? The author even says that it's useful and influential. > What we are doing at C4 is taking messy, conceptually challenging problems and turning them into something rigorous. We’re very phi

The last few years have seen a number of very interesting developments along the lines of understanding the natural world through the so-called "lens of computation." Some interesting talks can be found here [1] as well as an essa

> plenty of people who came out of their masters / PhD spouting stuff like this. This is a good point, but I think it speaks more to the degradation of the PhD as a signal, due to universities disproportionately caring about graduat

Similarly, I get bothered by movies and television involving the misuse of (usually decorative) mathematics.

This is a straw man and does a huge disservice to the complicated history behind complex numbers. [1] In particular, mathematicians came up with it first (the Italians, Cardano et al., if you don't count the greeks who did something fu

I don't think the author was trying to give a precise description of the problem. "Doubling the cube" is a term of art. It's like if he used the word "derivative" and you thought it meant a cheap copy of someth

This is the point when you realize you've dodged the core of my comment in favor of nitpicking. (and where are you getting this foot information from, anyway?)

> oh, geometrically? No. Algebraically works cleaner, and for any arbitrary positive solutions for r. I hope you're not being serious. Just in case you are, your algebra is wrong. I'm quite certain you didn't look up what

When the president consistently acts childishly (with corroboration from his staff, videos of him pushing others aside for photo ops, and countless other shenanigans), does one rationally conclude he is childish, or that he is playing &quot

You say that, and I'm aware of the historical context. But you cannot deny that the majority of the text is devoted to questions like which verbs are appropriate and how words as used in mathematics relate to their notions used in math

This appears to be a philosophy text, to my cursory glance. Definitely not like the advanced math texts I have read.

Since I wrote that comment I feel the itch to do it myself :) He said topology, but I don't think he meant what I'm thinking of: a torus! A Mobius band! The projective plane! My curiosity is getting the better of me.

I recall a study with LA demographic data that showed the statistical distribution of LA matches the distribution output by the Schelling model. Hazy on the details though :(

If you're so passionate about it, you should go implement these changes to show how the model fails. I would read that, if it were done well. It's not obvious to me that simply changing the radius or grid geometry would have the e

Personally, I have always found these patterns make more sense in a large-scale engineering context (to avoid others misusing a library) than a primer whose goal is to teach one about math. I don't think anyone would realistically use

Not being able to easily quantify the inefficiency of one kind of waste is a very simple reason to not be mad about it. And, of course, one can express a desire to want to fix one problem without being obligated to express the desire to fix

This is cool. I wonder how one might get involved.
