Isn’t the more intense number the 35,000 parameters? Why pick on the 40 algorithms?

Isn’t the more intense number the 35,000 parameters?
Why pick on the 40 algorithms?
- account73466 7y agoIf you try to optimize them and you deal with a black-box, then yes.
- asdfasgasdgasdg 7y agoNasdaq has about 3500 listed companies, so that's only ten parameters per company. Not that many. If you're talking about running the algorithm per market participant then it's an even weirder claim.
- account73466 7y agoSo you just assumed that parameters are defined company-wise?
- asdfasgasdgasdg 7y agoI wouldn't say I assumed anything. I would just say that the statement about number of parameters and algorithms is incoherent, or at least so vastly underspecified as to communicate no meaning.
- weego 7y agoNasdaq employees drink 15,000 cups of coffee a day, that's close to 2 parameters per cup
- projektfu 7y agoYes but if Nasdaq's total market cap is $30 trillion, that's about $750 billion per algorithm. Surely we need more algorithms.
- Ericson2314 7y agoNo billion left behind
- jklein11 7y agoI think the reason why I laughed is that I can't understand what 40 algorithms actually means. It probably takes more than 40 algorithms to accept a request at this url https://news.ycombinator.com/item?id=21730608 https://news.ycombinator.com/item?id=21730608 and return the response that you are seeing on your screen. That bullet in the article added no value to me as the reader.
- braindeath 7y agoAs far as imprecise journalism (let alone blatant inaccuracy goes) this is pretty inoffensive IMHO. It’s not even that far off. Algorithms can be composed. When we publish a paper on a complete ML application, the whole thing is generally referred to as “the algorithm” because it can be documented as precise set of steps from initial raw inputs to some kind of output. Just because there are literally thousands of applications of sorting and searching, matrix multiplies and what have you buried under the process doesn’t make it unclear what is being referred to.
- adatavizguy 7y agoAlmost all algorithms are composition of algorithms. Probably a good way to define a singular algorithm is the point a human has to be the source of its input. A self driving car is a composition of thousands of algorithms by definition -- a process that step by step calculates with an input and output which is every single method in all its code. However, for sake of conversation in the number of complete autonomous systems consider the car to be a single algorithm defined by the point a human has to be the originating input at the interface where the key gets turned to turn it on. I think this definition will be important in law because it is where we will define responsibility for actions of autonomous things.
- craftinator 7y agoI'm guessing you are more of an expert on the technology involved than the journalist writing this article, and thus not the target audience. Maybe look for other areas of value in it, and skip that particular bullet point. I imagine mechanical engineers often find laughable lines in Popular Mechanics as well...
- TheSpiceIsLife 7y agoSorry, I meant interesting not intense. Too late to edit now.
