5:00 AM | Scalable Robust Matrix Recovery: Frank-Wolfe Meets Proximal Methods
We mentioned Frank-Wolfe recently: Scalable Robust Matrix Recovery: Frank-Wolfe Meets Proximal Methods by Cun Mu, Yuqian Zhang, John Wright, Donald GoldfarbRecovering matrices from compressive and grossly corrupted observations is a fundamental problem in robust statistics, with rich applications in computer vision and machine learning. In theory, under certain conditions, this problem can be solved in polynomial time via a natural convex relaxation, known as Compressive […]

8:43 PM | Patches and specs
From Leslie Lamport: Every time code is patched, it becomes a little uglier, harder to understand, harder to maintain, bugs get introduced. If you don’t start with a spec, every piece of code you write is a patch. Which means…Read more ›

11:37 PM | FTL: Advanced Edition Adds More Space and an iPad Version
One of my favorite games of 2012 was FTL. It's a space sim roguelike-like unlike anything The game is deceptively simple and endlessly entertaining. In it, you control the crew of a starship on a desperate mission to stop the rebel alliance, or something like that. The upshot is that you control the crew, assigning them tasks like ship repair, arming the weapons, or cranking up the engines while traversing system after system. Because the game has roguelike elements, each time you play, the map […]

5:45 PM | 30 Days of Research Challenge
I’m a fan of 30 day challenges. I’ve been a regular participant in AcWriMo for a few years running, and I occasionally do 30 Days of Creativity in June. A few of my colleagues are participating in 30 Days of Biking this month, and Runner’s World famously does a holiday running streak, where you pledge […]

3:48 PM | What Is Linux?
Linux is an operating system (OS) for computers, in much the same way as Microsoft Windows (MSW) and Mac OS X are. An operating system is software that runs on a computer, to support applications and control the hardware. Applications are software programs that help you to do useful stuff on the computer, such as…Read more →

1:15 PM | Deep ConvNets; "Astounding" baseline for vision
Last night, Pierre Sermanet gave a talk on OverFeat and ConvNets. The meetup was triggered by one of the Pierre's post on Google+ where he mentioned an ArXiv preprint where some folks at KTH [2] used features from OverFeat [1,3] and an SVM to get results they called "astounding" and said so in the title of the paper ( CNN Features off-the-shelf: an Astounding Baseline for Recognition ). The use of such wording is rare (If you recall similar words such as "stunning" or "quite […]

10:08 AM | Actualités de la visualisation de données : 3 regards critiques
La carte qui attise la curiosité, le réseau illisible mais fascinant, les graphiques aux sources cachées par la simplicité visuelle,… autant d’éléments désormais récurrents dans les médias, communications politiques et scientifiques qu’il faut savoir décrypter. Si la nature des données est censée conditionner notre façon de les représenter, la marge de manoeuvre reste en effet […]

4:22 PM | Episode 251 - The Podcast of Truth - 4/3/2014
This week, Will, Norm, and Jeremy discuss the continuing implications of the Oculus/Facebook purchase, Oculus hiring Michael Abrash, rearview cameras in cars, Roku's HDMI stick, Gmail's birthday, Liars day, and DIY traffic jams. We recorded before BUILD and the Amazon Fire TV announcement, so expect to see that next week.

2:09 PM | From Direct Imaging to Machine Learning ... a rapid panorama (JIONC 2014)
I have attended, for the past three years, the "Journées d'imagerie optique non-conventionnelle" (or JIONC for short) organized at ESPCI (don't look, there is currently no website for these meetings) and felt that the generic dichotomy of looking at sensors and then reconstruction solvers needed some perspective. So I decided to put in an abstract for a presentation two hours before the deadline. As it turns out, the committee was overwhelmed with abstracts this time (more than […]

5:57 PM | Bits to Atoms: Designing and 3D-Printing Tested Nametags
Sometimes a project pops into your head and keeps popping up--on the subway, at work, during meetings, while making dinner, laying in bed trying sleep, etc., until you just have to do it in order to purge it. It occurred to me that the Tested logo would be perfect for a 3D print! With its simple geometric parts as well as the opportunity to demonstrate a variety of printing techniques, I couldn’t resist. I had made name badges before for my booth at Maker Faire and thought it was a good […]

4:00 PM | In Brief: Amazon Releases Fire TV Set-Top Box
A little late to the set-top party, Amazon held an event this morning to announce its own living room console, the Fire TV. It's everything you'd expect from a modern set-top box, a $100 machine running Android that will run the most popular streaming apps (aside from HBO Go and Vudu), play games, and connect to mobile devices like Amaon's Kindle Fire tablet. Amazon emphasized the hardware specifications of its console--it runs on a quad-core Qualcomm Krait 300 SoC with a dedicated Adreno 320 […]

3:30 PM | Bayesian Pursuit Algorithms - implementation -
Bayesian Pursuit Algorithms by Cedric Herzet, Angélique Drémeau This paper addresses the sparse representation (SR) problem within a general Bayesian framework. We show that the Lagrangian formulation of the standard SR problem, i.e. $\x^\star=\argmin_\x \lbrace \| \y-\D\x\|_2^2+\lambda\| \x\|_0 \rbrace$, can be regarded as a limit case of a general maximum a posteriori (MAP) problem involving Bernoulli-Gaussian variables. We then propose different tractable […]
