7:56 PM | Solutions To the Fermi Paradox
The Fermi Paradox is endlessly fascinating to me. The paradox is simple--there are somewhere between 100 billion and 400 billion stars in our galaxy, cosmologically speaking our Sun is relatively young, and our species is brand new. If life is abundant in the universe, why haven't we heard from anyone else yet?This article does a good job breaking down the possible reasons we haven't made contact yet. The explanations range from the macabre to the comical. Personally, I'm optimistic that the […]

4:05 PM | PyQt5 support in Matplotlib
My pull-request for matplotlib to add PyQt5 support has been accepted and merged, meaning PyQt5 support will be available in the upcoming v1.4.0 release of matplotlib. Based off original work by @badders this re-implements the Qt backend structure as Qt5-first, with Qt4 wrappers for compatibility. It’s hoped that this will simplify things going forward, keeping the latest API cleanest with minimal code-cruft. Thanks to the matplotlib team for the support in getting the PR up […]

4:00 PM | In Brief: FAA Claims Jurisdiction Over FPV RC Flying
The FAA Modernization and Reform Act of 2012 included verbiage which prevents the Federal Aviation Administration (FAA) from imposing any new rules on model aircraft. This exemption, which is defined in Section 336 of the law, applies so long as a short list of requirements is met by the operator and model. Like so many legislative documents, the five exemption requirements leave numerous grey areas. Thus, the FAA recently issued its interpretation of the exemption and how the agency intends to […]

3:30 PM | Random Branches
It's Friday afternoon, it's Hamming's time. Let us push the argument of About t'em Random Projections in Random Forests further.Leo Breiman, and many others afterwards, were concerned about linking Adaboost with Random Forests (see 7. Conjecture: Adaboost is a Random Forest). Let us look at it some other way, Random Forests are a set of randomized trees built node by node based on the sequential determination of an optimal split of groups of elements according to a certain metric […]

3:14 PM | Le rêve du multilinguisme dans la science : l’exemple (malheureux) du colloque #DH2014
L’anglais est-il définitivement la langue de la science ? Peut-on encore se permettre de communiquer en français, en allemand ou en italien ? Doit-on, à contre-courant d’un sens pratique réducteur, mettre en place des mécanismes qui permettent à des chercheurs de soumettre des communications dans leur propre langue dans des colloques internationaux ? Illustrant ce questionnement, le colloque annuel des humanités numériques […]

Why is soccer the world’s most important sport? I could write about the sport. Say that it is the inherent unfairness of the sport which makes it so appealing (yes, the unfairness is what is appealing; the fact that a … Continue reading →

10:29 AM | Impression Store: Compressive Sensing-based Storage for Big Data Analytics
Here is a related use of compressive sensing: simple storage for Ads. Overall, I am very surprised that none of the references include any of the sketching contribution to compressive sensing [1,2]. In retrospect, it was wise for us to invite Muthu and Sam at the last Paris Machine Learning Meetup [3] so that these techniques don't get re-discovered everytime.Impression Store: Compressive Sensing-based Storage for Big Data Analytics by Jiaxing Zhang, Ying Yan, Liang Jeff Chen, […]

10:32 PM | Pebble vs. Android Wear Smart Watch Features
Yesterday, Google laid out more of its vision and plans for Android Wear, the software platform for manufacturers like LG, Samsung, and Motorola to build Android-compatible smart watches. And while smart watches like the Pebble, Metawatch, and Samsung's own Tizen-based Galaxy Gear have been around for a while, Google's offering may be the catalyst for the general public to start taking these wearable devices seriously--at least until Apple makes a smart watch announcement. But not all smart […]

9:20 PM | A Physically Universal Cellular Automaton
It’s been understood for decades that, if you take a simple discrete rule—say, a cellular automaton like Conway’s Game of Life—and iterate it over and over, you can very easily get the capacity for universal computation.  In other words, your cellular automaton becomes able to implement any desired sequence of AND, OR, and NOT gates, store and retrieve […]

7:56 PM | The Science of Roasting and Brewing Coffee
This UNCTV Science segment gives a peek inside Counter Culture coffee to show a bit about the science of roasting coffee and does a great job detailing the processes that take place inside the coffee bean as its roasted, ground up, and then brewed.

7:29 PM | In Praise of the Mechanical Typewriter
When was the last time you used a mechanical typewriter? With the current state of computing, there's no need at all to use one--even the computer keyboard is losing ground to touch and voice interfaces. Yet if you grew up with a typewriter, and learned to spell your name on one, you’ll be happy to learn that like vinyl, typewriters are indeed making a comeback. Even if not to be used regularly, then at least to be appreciated.All around the world, typewriter enthusiasts have been […]

6:00 PM | In Brief: Designing a Car for the Ergonomics of Driving
For all the new technology and interface points we're putting into the car, there are a few things about driving that just won't change. The next generation of cars may all have massive touchscreens, voice commands, and smartphone connectivity, but we'll very likely still be using the good old steering wheel and pedals to actually drive around. That's not to say alternative car interface paradigms haven't been tried before. ArsTechnica's Automotive Editor Jonathan Gitlin lays out the history of […]

2:31 PM | About t'em Random Projections in Random Forests
If anything comes out of Kaggle competitions, it is that Random Forests [4,5,6], while not consistently giving the best scores, have pretty good results most of the times. Random Forest [4] typically is a technique of supervised learning in Machine Learning parlance.Recently, some folks have made some sorts of connection with these techniques and compressive sensing or Johnson-Lindenstrauss. In one of the earliest case, the intention was to use the sparsity of the label within a generally […]

9:50 AM | The Case for Leaving Shipwrecks at the Bottom of the Ocean
For over 500 year historians have wondered: where in the world is Christopher Columbus' lost ship? The Santa Maria was the largest of three ships to sail across the Atlantic on Columbus' first voyage, but the only one to sink.In May, a well-known undersea explorer by the name of Barry Clifford announced he may have found the missing ship off the coast of Haiti. It's there that records say the Santa Maria hit reef and met its watery end. But if that turns out to be the case, don't expect to see […]

8:19 AM | In Brief: Google Cardboard Is Low-Budget Virtual Reality
Google I/O began today, and there were a ton of takeaways from the marathon keynote this morning. We'll be recapping the announcements in this week's podcast, as well as getting some analysis from our Android expert, Ryan Whitwam. In the meantime, there's one bit of interesting news from I/O that didn't make it in the keynote. It's a project called Google Cardboard, and it's not a gag. Cardboard is a fold-out kit handed out to I/O attendees, which when assembled resemble a Viewmaster. It's […]

I asked Emmanuel Candes about the presentations, which for the first time, introduced some people to compressive sensing and its attendant phase transitions. Here is what he responded:Igor,If you go here: http://statweb.stanford.edu/~candes/OldTalks.html, you will see three talks with phase transition diagrams. The first two have taken place on May 3 and May 28, 2004. The third on July 14, 2004.Thanks,EmmanuelThanks Emmanuel ! so it's been ten years, uh...Phil Schniter just […]

9:27 PM | Integrated Information Theory: Virgil Griffith opines
Remember the two discussions about Integrated Information Theory that we had a month ago on this blog?  You know, the ones where I argued that IIT fails because “the brain might be an expander, but not every expander is a brain”; where IIT inventor Giulio Tononi wrote a 14-page response biting the bullet with mustard; and where […]
