Facebook's war on free will | Technology | The Guardian - 0 views

  • Though Facebook will occasionally talk about the transparency of governments and corporations, what it really wants to advance is the transparency of individuals – or what it has called, at various moments, “radical transparency” or “ultimate transparency”. The theory holds that the sunshine of sharing our intimate details will disinfect the moral mess of our lives. With the looming threat that our embarrassing information will be broadcast, we’ll behave better. And perhaps the ubiquity of incriminating photos and damning revelations will prod us to become more tolerant of one another’s sins. “The days of you having a different image for your work friends or co-workers and for the other people you know are probably coming to an end pretty quickly,” Zuckerberg has said. “Having two identities for yourself is an example of a lack of integrity.”
  • The essence of the algorithm is entirely uncomplicated. The textbooks compare them to recipes – a series of precise steps that can be followed mindlessly. This is different from equations, which have one correct result. Algorithms merely capture the process for solving a problem and say nothing about where those steps ultimately lead.
  • For the first decades of computing, the term “algorithm” wasn’t much mentioned. But as computer science departments began sprouting across campuses in the 60s, the term acquired a new cachet. Its vogue was the product of status anxiety. Programmers, especially in the academy, were anxious to show that they weren’t mere technicians. They began to describe their work as algorithmic, in part because it tied them to one of the greatest of all mathematicians – the Persian polymath Muhammad ibn Musa al-Khwarizmi, or as he was known in Latin, Algoritmi. During the 12th century, translations of al-Khwarizmi introduced Arabic numerals to the west; his treatises pioneered algebra and trigonometry. By describing the algorithm as the fundamental element of programming, the computer scientists were attaching themselves to a grand history. It was a savvy piece of name-dropping: See, we’re not arriviste, we’re working with abstractions and theories, just like the mathematicians!

  • The algorithm may be the essence of computer science – but it’s not precisely a scientific concept. An algorithm is a system, like plumbing or a military chain of command. It takes knowhow, calculation and creativity to make a system work properly. But some systems, like some armies, are much more reliable than others. A system is a human artefact, not a mathematical truism. The origins of the algorithm are unmistakably human, but human fallibility isn’t a quality that we associate with it.
  • Nobody better articulates the modern faith in engineering’s power to transform society than Zuckerberg. He told a group of software developers, “You know, I’m an engineer, and I think a key part of the engineering mindset is this hope and this belief that you can take any system that’s out there and make it much, much better than it is today. Anything, whether it’s hardware or software, a company, a developer ecosystem – you can take anything and make it much, much better.” The world will improve, if only Zuckerberg’s reason can prevail – and it will.
  • Data, like victims of torture, tells its interrogator what it wants to hear.
  • Very soon, they will guide self-driving cars and pinpoint cancers growing in our innards. But to do all these things, algorithms are constantly taking our measure. They make decisions about us and on our behalf. The problem is that when we outsource thinking to machines, we are really outsourcing thinking to the organisations that run the machines.
  • The engineering mindset has little patience for the fetishisation of words and images, for the mystique of art, for moral complexity or emotional expression. It views humans as data, components of systems, abstractions. That’s why Facebook has so few qualms about performing rampant experiments on its users. The whole effort is to make human beings predictable – to anticipate their behaviour, which makes them easier to manipulate. With this sort of cold-blooded thinking, so divorced from the contingency and mystery of human life, it’s easy to see how long-standing values begin to seem like an annoyance – why a concept such as privacy would carry so little weight in the engineer’s calculus, why the inefficiencies of publishing and journalism seem so imminently disruptable

Sorting algorithms as dances - 3 views

  •  
    You may well have seen many simulations of sorting algorithms that aim to show in novel ways how the algorithm works or perhaps doesn't work quite as well as it should. However I guarantee that you have never seen anything quite in the same league as the videos made by Sapientia University - they are simply crazy but in the nicest possible way.

  •  
    "The Universal Typeface is a constantly evolving, algorithmically produced font created by averaging hundreds of thousands of handwriting samples submitted to BIC's website. Anyone with a touchscreen can help shape the Universal Typeface by linking their phone or tablet to the website and writing directly on the touchscreen - the lettering is quickly transferred to the Universal Typeface algorithm."

An update to our search algorithms - Inside Search - 0 views

  •  
    "We aim to provide a great experience for our users and have developed over 200 signals to ensure our search algorithms deliver the best possible results. Starting next week, we will begin taking into account a new signal in our rankings: the number of valid copyright removal notices we receive for any given site. Sites with high numbers of removal notices may appear lower in our results. This ranking change should help users find legitimate, quality sources of content more easily-whether it's a song previewed on NPR's music website, a TV show on Hulu or new music streamed from Spotify.

'Mathwashing,' Facebook and the zeitgeist of data worship - Technical.ly Broo... - 0 views

  •  
    In an interview with Tyler Wood, Fred Benesen explains how and why data is far more subjective than we always recognise. The term mathwashing should be more of a warning to fellow technologists: don't overlook the inherent subjectivity of building things with data just because you're using math. Algorithm and data driven products will always reflect the design choices of the humans who built them, and it's irresponsible to assume otherwise.

"Something" is Wrong with Google (since 2004) | Search Engine Journal - 3 views

  •  
    It never ceases to amaze me how Google has become such an integral part of our lives. Search has evolved in such colossal proportions and especially with the advent of Google instant my belief that Google can actually read my mind has only been fortified. Search Marketers around the world are always on their Toes and as Google states "Don't try to follow our algorithm but try to think about the direction in which we are heading, build content for the users and not the search engines". I sometimes wonder if Google was actually a person he would be an amazing election candidate. But then again the high and mighty also have their share of secrets, secrets that should never come up, what I am about to reveal can be touted as one of the many chapters of the Da Vinci of Google.

Twitter Co-Founder Evan Williams Lays Out His Plan For The Future Of Media | TechCrunch - 1 views

  •  
    "Twitter Co-Founder Evan Williams has an ambitious new plan: to shift our daily reading habits away from consuming incremental news bites and towards engaging with enlightened ideas curated by an intelligent algorithm. Ordinarily, such a goal would seem utopian, were it not for the fact that Williams is among a handful of Internet pioneers who have disrupted the media industry multiple times.

Is Google really filtering my news? - Librarian of Fortune - 1 views

  •  
    "I've been reading snippets of Eli Pariser's book, The Filter Bubble: What the Internet Is Hiding From You. He leads off the book with a discussion of the effect of Google's "personalization" feature on the ranking of search results. This feature uses 54 signals (what browser version you're using, your prior searches, geographic location, and so on) to customize search results for each user. Pariser was concerned about this and tested it by asking two friends to run the same search at the same time and comparing the results. He found that the results were disturbingly different, and concluded that search engines are "increasingly biased to share our own views. More and more, your computer monitor is a kind of one-way mirror, reflecting your own interests while algorithmic observers watch what you click.""

    "Rather than taking Kang's words as a warning against wanting your brain cake and eating it too, I took them as a reminder that our children are entering a time when traversing context has never been as complex as it is now. When it's time to drop a verse, can they demonstrate eloquence and elaborateness? And then, in times when we need to speak a language which eliminates ambiguity in favour of transferable clarity and concision, will our kids be able to write a masterclass algorithm?" Reminded me of the discussion brought up during the interview with Ian Guest where Daryl and Tony mused about teaching code.

Twitter, algorithms, and digital dystopias | Doug Belshaw's blog - 2 views

  •  
    "This may be overstating or overthinking the situation. Twitter is just a website. Yet, I can point to many opportunities, jobs, and (most importantly) friendships that sprung from it. Some married friends met on Twitter. It's tempting to give an importance to the service for those of us who joined early and were able to reap these benefits, but that doesn't mean Twitter needs to stick around forever. It matters. Or mattered. To me, I'm unsure which just yet."

How Artificial Intelligence (AI) Will Change Magento eCommerce stores - TI Technologies - 0 views

  •  
    As digital transactions become the definitive method of purchasing goods and services, leading eCommerce firms are exploring how AI can enhance brand competitiveness and customer loyalty. Artificial Intelligence is set to be a game-changer to shape the next stage of the e-commerce evolution. Artificial intelligence provides passel of opportunities to the e-commerce industry where retailers compete to provide the maximum customer convenience, by providing the ultimate shopping experience. With continuous advances in digital voice technology, AI tools such as Alexa, Cortana, and Watson, are gracing headlines almost daily, hinting at the wide scope of opportunities it has to revolutionize eCommerce stores. Here we show 6 amazing applications to use Artificial Intelligence in eCommerce. * Create customer-centric search- By implementing Artificial intelligence in Magento creates purchase assistants that target the right users, with the right messages at the right time.AI programs can rely on self-learning algorithms to deconstruct Bigdata of thousands of customers and create targeted user experiences, hence ruling out any human-bias or error. * Context-based search- Product Search functionality is an integral part of a Magento store as the shopping process begins with the search for relevant products. If Magento individualizes some impressive extensions, they might be nothing as compared to the effectiveness of AI-powered searches. Here usual searches rely on the Keywords entered by the user and only when there is a correct match, your searches will dish out the right search results. But AI-powered product searches will look for the context of the search, utilize the capability of Natural Language Process to generate context-based search terms rather than typical keywords. * Facilitate Purchase Decisions- Purchase Assistants are something that is still not fully released. Using the concept of virtual Purchase assistant we can cut down the time spent by shoppers
