Quotes About Algorithms

The success of Google Flu Trends became emblematic of the hot new trend in business, technology, and science: big data and algorithms. "Big data" can mean many things, but let's focus on the found data we discussed in the previous chapter, the digital exhaust of web searches, credit card payments, and mobile phones pinging the nearest cell tower, perhaps buttressed by the administrative data generated as organizations organize themselves.

Hearing the anecdote, it's easy to assume that Target's algorithms are infallible—that everybody receiving coupons for onesies and wet wipes is pregnant. But nobody ever claimed that it was true.

The likes of Google and Target are no more keen to share their datasets and algorithms than Newton was to share his alchemical experiments. Sometimes

It takes you 500,000 microseconds just to click a mouse. But if you're a Wall Street algorithm and you're five microseconds behind, you're a loser.

Good programming is not born from mere technical competence. I've seen highly intellectual programmers who can produce intense and impressive algorithms, who know their language standard by heart, but who write the most awful code.

Turing showed that just as the uncertainties of physics stem from using electrons and photons to measure themselves, the limitations of computers stem from recursive self-reference. Just as quantum theory fell into self-referential loops of uncertainty because it measured atoms and electrons using instruments composed of atoms and electrons, computer logic could not escape self-referential loops as its own logical structures informed its own algorithms.12

Despite the metadata attached to each tweet, and despite trails of retweets and 'favorite' tweets, the Twitter corpus lacks the latticework of hyperlinks that makes Google's algorithms so potent. Twitter's famous hashtags - #sandyhook or #fiscalcliff or #girls - are the crudest sort of signposts, not much help for smart searching.

Competitors argue that Google rigs its search algorithms to demote listings for competing search engines. Many of the allegations of demotion come generally from sites of pretty questionable quality, such as Nextag and Foundem. Some of Google's primary competitors in 'specialized search' clearly place well in search results - Amazon and Yelp.

CRYPTOLOGY, as the union of cryptography and cryptanalysis is called.

Any number that can be created by fetishistically multiplying 2s by each other, and subtracting the occasional 1, will be instantly recognizable to a hacker.

mailing list, which is where all of the cool guys like John Cantrell hang out to discuss the very latest hashing algorithms and pseudo-random-number generators.

In this book we will be focusing on two types of machine learning algorithms: decision trees and random forests. However, there are many different types of algorithms used in machine learning, such as neural networks, naive bayes, and k-means clustering.

the word algorithm was derived from al Khwarizm

Fashion data was used to build AI models to help Steve Bannon build his insurgency and build the alt-right. We used weaponized algorithms. We used weaponized cultural narratives to undermine people and undermine the perception of reality. And fashion played a big part in that.

Facebook and Google are essentially an advertising duopoly, and we have almost no idea how their algorithms work.

For his birthday, she'd bought him an iPhone, which he'd returned to the store. He'd apologized, saying that it was a thoughtful gift, but he didn't want to carry a tiny high-powered mainframe on which he could compute astronomical algorithms, or check Facebook. He wanted a phone.

I took a computer-science course to fill a prerequisite at Stanford, and I realized that every day was a new problem, and every day you got to think about how to solve something new, how to reason through something new, how to develop an algorithm to solve for something you hadn't worked on before.

It's difficult to make your clients understand that there are certain days that the market will go up or down 2%, and it's basically driven by algorithms talking to algorithms. There's no real rhyme or reason for that. So it's difficult. We just try to preach long-term investing and staying the course.

Fantasy sports went a long way toward developing the sabermetrics formulas used not only by oddsmakers but general managers in hiring players. So the amateur fantasists ended up creating some of the algorithms that Oakland GM Billy Bean's statisticians used to win games with less salary money available for star players.

Good SEO work only gets better over time. It's only search engine tricks that need to keep changing when the ranking algorithms change.

Once you see the problems that algorithms can introduce, people can be quick to want to throw them away altogether and think the situation would be resolved by sticking to human decisions until the algorithms are better.

If someone stole your keys to encrypt the data, it didn't matter how secure the algorithms were.

So the problem is not the algorithms, or the big datasets. The problem is a lack of scrutiny, transparency, and debate.

Gerir uma empresa com trabalhadores que não têm horário, que se limitam a ligar uma aplicação quando querem trabalhar e que concorrem com outros trabalhadores para qualquer trabalho que esteja disponível exige um poderoso conjunto de algoritmos, para assegurar que a oferta de trabalhadores e de clientes se mantenha num equilíbrio dinâmico.
