Kevin Slavin: How algorithms shape our world. » A Speculative Post on the Idea of Algorithmic Authority Clay Shirky. Jack Balkin invited me to be on a panel yesterday at Yale’s Information Society Project conference, Journalism & The New Media Ecology, and I used my remarks to observe that one of the things up for grabs in the current news environment is the nature of authority.
In particular, I noted that people trust new classes of aggregators and filters, whether Google or Twitter or Wikipedia (in its ‘breaking news’ mode.) I called this tendency algorithmic authority.

A smart-object recognition algorithm that doesn’t need humans. (Credit: BYU Photo) BYU engineer Dah-Jye Lee has created an algorithm that can accurately identify objects in images or video sequences — without human calibration.
“In most cases, people are in charge of deciding what features to focus on and they then write the algorithm based off that,” said Lee, a professor of electrical and computer engineering. “With our algorithm, we give it a set of images and let the computer decide which features are important.” Humans need not apply. Can Algorithms Find the Best Intelligence Analysts? The U.S intelligence community has a long history of blowing big calls — the fall of the Berlin Wall, Saddam’s WMD, 9/11.
But in each collective fail, there were individual analysts who got it right. Now, the spy agencies want a better way to sort the accurate from the unsound, by applying principles of mathematics to weigh and rank the input of different experts. Iarpa, the intelligence community’s way-out research arm, will host a one-day workshop on a new program, called Aggregative Contingent Estimation (ACE). Network Science.
Complex systems made simple. Albert-László Barabási and Yang-Yu Liu, together with their collaborator Jean-Jacques Slotine at M.I.T., have developed a method for observing large, complex systems.
In the image above, red dots represent sensor nodes, which are required to reconstruct the entire internal state of one such system. Image by Mauro Martino. Pinterest’s Founder: Algorithms Don’t Know What You Want. In 2012 the startup Pinterest became a peer of more established social sites by offering things that they didn’t—an attractive design, a focus on images rather than text, and a mostly female population of users.
On Pinterest, people use virtual “pinboards” to curate collections of images related to their hobbies and interests, discovering new items for their virtual hoards on the boards of friends and in the site’s personalized recommendations. Tom Simonite, MIT Technology Review’s senior IT editor, recently spoke with Ben Silbermann, Pinterest’s cofounder and CEO, about the company’s popularity. What was the need you were trying to fill when you created Pinterest? We started making Pinterest around 2009, when there was a lot of attention being paid to social services that were focused on real-time text-based feeds like Facebook and Twitter. We felt the things that we enjoyed doing in the real world were hard to express in that format. The Rise of the Algorithmic Medium. The 10 Algorithms That Dominate Our World. A clustering algorithm based on swarm intelligence. This paper focuses on swarm intelligence based clustering algorithm.
A clustering algorithm based on swarm intelligence is systematically proposed. It derived from a basic model interpreting ant colony organization of cemeteries. Some important concepts, such as swarm similarity, swarm similarity coefficient and probability conversion function are also proposed. The Top 10 Algorithms in Data Mining. Trust Is Not An Algorithm: Big Data Are Hot, But They Also Miss A Lot. [Illustration from By some accounts the world’s information is doubling every two years.
This impressive if unprovable fact has got many people wondering: what to do with it? Dictionary of Algorithms and Data Structures. This web site is hosted by the Software and Systems Division, Information Technology Laboratory, NIST in collaboration with the FASTAR group.
Development of this dictionary started in 1998 under the editorship of Paul E. Black. This is a dictionary of algorithms, algorithmic techniques, data structures, archetypal problems, and related definitions. Algorithms include common functions, such as Ackermann's function. List of algorithms. The following is a list of algorithms along with one-line descriptions for each.
The video shows the process — and matched “audibilisation” — of 15 different sorting algorithms dreamt up by computer scientists. While they all use different approaches, like divide and conquer or comparison sorting, they all have one fundamental aim: to sort random shuffles of integers into order. Sorting Algorithm Animations. List of terms relating to algorithms and data structures. The NIST Dictionary of Algorithms and Data Structures is a reference work maintained by the U.S. National Institute of Standards and Technology. It defines a large number of terms relating to algorithms and data structures.
For algorithms and data structures not necessarily mentioned here, see list of algorithms and list of data structures. This list of terms was originally derived from the index of that document, and is in the public domain, as it was compiled by a Federal Government employee as part of a Federal Government work. Some of the terms defined are:
Contourner les algorithmes. Inférence bayésienne. Moteur d'inférence. Bayesian Network - AI Depot. Statistical inference. In statistics, statistical inference is the process of drawing conclusions from data that are subject to random variation, for example, observational errors or sampling variation. Initial requirements of such a system of procedures for inference and induction are that the system should produce reasonable answers when applied to well-defined situations and that it should be general enough to be applied across a range of situations. Inferential statistics are used to test hypotheses and make estimations using sample data.
The outcome of statistical inference may be an answer to the question "what should be done next? ", where this might be a decision about making further experiments or surveys, or about drawing a conclusion before implementing some organizational or governmental policy. The Algorithm: Idiom of Modern Science. By Bernard Chazelle hen the great Dane of 20th century physics, Niels Bohr, was not busy chewing on a juicy morsel of quantum mechanics, he was known to yap away witticisms worthy of Yogi Berra.
The classic Bohrism “Prediction is difficult, especially about the future” alas came too late to save Lord Kelvin. Just as physics was set to debut in Einstein's own production of Extreme Makeover, Kelvin judged the time ripe to pen the field's obituary: “There is nothing new to be discovered in physics now.” Human Workers, Managed by an Algorithm.
