some of the comments on this article are so embarrassing. It's just a short and clearly written article on a pretty simple and fundamental type of problem in information theory. Similar ideas are the basis for the systems we use in data compression and transmission and error correction among other things.

Maybe better to think for a few seconds before dismissing the problem as pointless and claiming to hate it.


It describes the problem, but not fully. Either do it properly or link to a complete description.

In this case, unlike what the article states as the problem, the point seems not to be how to send a real number using a single bit, but how to aggregate such bits from many agents that measure some shared thing.

That's two very, very different things.


No, that's a point.


The table's the point cloud. I guess if you want to be really pedantic about grammar then I should point out that a set of one item is still a set. :-)


True - I misread your post. Your first post was intriguing but the second was dismissive. Surely there's more to be said than data sets are point clouds? Images are points in R^N too, right?


If your unit of recognition was a set of images, and not an image alone, then you would have permutation symmetry and want to use point cloud techniques to design your first layer. So yes images are points in R^N.


Oh thanks, this was not clear from your other posts: the whole table is used as a data point, not the line. Much clearer now, why you would compare this to point clouds


Remember when people claimed that the bitcoin block size couldn't be increased because we would sacrifice decentralization? Well look where we are now...


This must be some new kind of marketing from big-leetcode.


The cynic in me also wonders if this is propaganda I just don’t k is from where. Who would benefit from “Leetcode tests intelligence, only inherently intelligent people can program, therefore nobody should even try to be a software engineer unless they can leetcode” all of which is false.


A bit depressing to be an advertising, I think.


I bought my headphones (Audio Technica ATH-AD700s) when I was in school. I still use them now and they sound just as good as anything else you could buy.

Not quite generational inheritance but I can't think of anything else I bought back then that I still use. It's pretty satisfying when I think about it.


Schrodinger wrote about life from this perspective in an article also called "What is life?"

I thought it was pretty good.

Yes exactly. It's a great read. Here is the snippet about my other comment (p.25)

> Every process, event, happening -call it what you will; in a word, everything that is going on in Nature means an increase of the entropy of the part of the world where it is going on. Thus a living organism continually increases its entropy -or, as you may say, produces positive entropy -and thus tends to approach the dangerous state of maximum entropy, which is of death. It can only keep aloof from it, i.e. alive, by continually drawing from its environment negative entropy -which is something very positive as we shall immediately see. What an organism feeds upon is negative entropy. Or, to put it less paradoxically, the essential thing in metabolism is that the organism succeeds in freeing itself from all the entropy it cannot help producing while alive.


for fun


In addition to all those negatives, they don't do much help either. As if a phone call to a stranger will make any difference to someone who's contemplating suicide.
