Redefining optimal When you’re trying to use models to probe the behavior of a complex biological system, there usually comes a point where you have to “fit parameters”. This happens because the model is trying to build up a macroscopic picture from underlying features that may be impossible to measure. For example, in the case of tumor growth, your model might use local nutrient density as a parameter that affects the rate of the growth of individual cells in the tumor and therefore the growth of the tumor overall. But nutrient density might not be possible to measure, and so you would have to use experimental data on something that’s easier to measure (e.g. how rapidly tumors grow) to deduce how nutrient density changes across the tumor.

Après l'open-data la nouvelle tendance tout droit venue des US sera-t-elle le « big data » ? D’un récent voyage dans la Silicon Valley (merci aux amis du Orange Institute), je rentre avec une conviction : tout ce que nous connaissions du web va changer à nouveau avec le phénomène des big data. Il pose à nouveau, sur des bases différentes, presque toutes les questions liées à la transformation numérique. En 2008, l’humanité a déversé 480 milliards de Gigabytes sur Internet. En 2010, ce furent 800 milliards de Gygabytes, soit, comme l’a dit un jour Eric Schmidt, plus que la totalité de ce que l’humanité avait écrit, imprimé, gravé, filmé ou enregistré de sa naissance jusqu’en 2003. Ces données ne sont pas toutes des œuvres.

Mapping a World of Human Activity With the world networked on an unprecedented scale, and the global population hitting 7 billion only weeks ago, we are living in a uniquely interconnected era, creating new opportunites and dependencies. It's the result of millenia of exploration, travel, exploitation, and innovation, and the Anthropocene, meaning “the new human-dominated period of the Earth’s history,” is a term coined in 2000 to describe this epoch.
La veille hebdomadaire des journalistes de données d'OWNI vous propose cette semaine de vous data-situer dans l'humanité, de visualiser votre dîner ou encore d'ouvrir les données de la Bible... Présenter les volumes d’importations et d’exportations des pays du globe, depuis 1962 : complexe ? Un peu, mais the Observatory of Economic complexity (l’Observatoire de la complexité économique), ne recule pas devant la difficulté, comme son nom l’indique. Les data en forme
Visualization of the Week: 7 billion humans The world population is expected to hit seven billion some time in the next few days. The United Nations has a countdown clock, of sorts, with a counter ticking steadily forward. The Guardian, along with the Spanish design house Bestario’s, has taken data from the U.N. to create a visualization of changes in global population.
Wrapping your brain around data online can be challenging, especially when dealing with huge volumes of information. And trying to find related content can also be difficult, depending on what data you’re looking for. But data visualizations can make all of that much easier, allowing you to see the concepts that you’re learning about in a more interesting, and often more useful manner. Below are 50 of the best data visualizations and tools for creating your own visualizations out there, covering everything from Digg activity to network connectivity to what’s currently happening on Twitter.

A Relection on the past year: Thanks to you for continuing to make this blog a success. Writing it has given me much enjoyment over the years, and I have learned much from your comments as well as from the visualization projects of many colleagues. 2013 also saw the publication of my new book Numbersense: How to Use Big Data to Your Advantage (link). I thank those of you who have purchased the book, and supported my writing. For those who haven't, please check it out. I have also been speaking at various events, mostly about interpreting data analyses published in the mass media, and building effective data analytics teams.

It can get pretty quiet here. I tend to post on Bostonography or Axis Maps a bit more often. Six map links that every cartographer has seen a million times By Andy Woodruff on 14 August 2013 Blog
Yesterday a bunch of friends were tweeting about the new LinkedIn InMaps web app (part of LinkedIn Labs), so I had to check it out for myself. Wow, wow, wow! InMaps are data visualizations of your professional network, based on LinkedIn connections, with you as the center node. I’ve been waiting years for LinkedIn to finally get its act together and start offering up analytics based on all the data we willingly store within it — but rarely make use of.
