Algorithms Quotes

“My experience is that journalists report on the nearest-cliche algorithm, which is extremely uninformative because there aren't many cliches, the truth is often quite distant from any cliche, and the only thing you can infer about the actual event was that this was the closest cliche. It is simply not possible to appreciate the sheer awfulness of mainstream media reporting until someone has actually reported on you. It is so much worse than you think.”

“Klout and various measurements of influence are fun. I love to see where I score on them, but there's a computer algorithm behind the calculation. If there's an algorithm, it can be gamed. Even if it's not gameable, you have to take a leap of faith that the number of followers, retweets, mentions, whatever really mean something.”

“The classes of problems which are respectively known and not known to have good algorithms are of great theoretical interest. [...] I conjecture that there is no good algorithm for the traveling salesman problem. My reasons are the same as for any mathematical conjecture: (1) It is a legitimate mathematical possibility, and (2) I do not know.”

“I'm less interested in uniqueness than in goodness. I see so many concerts where the program notes are more interesting than the music. I remember talking to one composer who went through the most complicated mathematical algorithm to generate some material from scratch. It took weeks and weeks, and he came up with a C major chord. For me, honesty is more interesting than originality.”

“What geographic profiling does is it takes a look at the locations of a connected series of incidents - say murders in a serial murder case or robberies in a serial bank robber case - and it spatially analyzes the point pattern of incidents, and creates a probability surface from those, working from the basis of an algorithm that says people offend close to where they live, but not too close.”

“Some people have set up sort of "gotcha" algorithms that apparently crawl through psychology articles and look for fraudulent p-values [a measure of the likelihood that experimental results weren't a fluke]. But they're including rounding errors that don't change the significance levels of the results, and they're doing it anonymously.”

“Google has - at least at this point - maintained the line where it keeps organic results separate from the advertisements. But over time - so in other words, you still get the - there still are honest to goodness results which are based on an algorithm which is based on how important or how many people link to that particular site, so there's that. At the very beginning, there were unobtrusive advertisements on the side that sort of showed up when you typed in certain phrases. Over time, the amount of real estate that those ads take up has increased.”

“With recidivism algorithms, for example, I worry about racist outcomes. With personality tests [for hiring], I worry about filtering out people with mental health problems from jobs. And with a teacher value-added model algorithm [used in New York City to score teachers], I worry literally that it's not meaningful. That it's almost a random number generator.”

“We don't let a car company just throw out a car and start driving it around without checking that the wheels are fastened on. We know that would result in death; but for some reason we have no hesitation at throwing out some algorithms untested and unmonitored even when they're making very important life-and-death decisions.”

“The Facebook algorithm designers chose to let us see what our friends are talking about. They chose to show us, in some sense, more of the same. And that is the design decision that they could have decided differently. They could have said, "We're going to show you stuff that you've probably never seen before." I think they probably optimized their algorithm to make the most amount of money, and that probably meant showing people stuff that they already sort of agreed with, or were more likely to agree with.”

“Back in the really early days, the men went out hunting, the women stayed home with the kids, and would hold the kid in one arm against the heart, so that's the left, and with the right arm they would throw. And it turns out you cannot make that calculation in real time. You have to have an algorithm set up. So these brain mechanisms evolved in order to do that, and when they evolved, the thing is that where there is a useful capability it often adapts to places it wasn't evolved for.”
