5:00 AM | Compressive Sampling of Polynomial Chaos Expansions: Convergence Analysis and Sampling Strategies
The sensing matrices in Uncertainty Quantification are very structured and so it is sometimes difficult to use solvers relying on gaussian measurement matrices and one wonders if solvers different from L1 could be contemplated in light of the recent SwAMP thing. Anyway, today's paper investigate in a deep fashion this subject. Let us note the use of phase transition as a comparison tool, great !Compressive Sampling of Polynomial Chaos Expansions: Convergence Analysis and Sampling […]

10:45 PM | Testing: Sony RX100 MK III Compact Camera
I've been on the hunt for a pocket camera to complement my DSLR, and spent time with cameras with sensors ranging from micro 4/3 to full-frame. My test of Sony's RX100 Mark II made me seriously consider the trade off between body size and sensor size. There were several things that held it back from being ideal for my day to day use, but I realized that getting a compact camera with an APS-C or Full-Frame sensor would compete too directly with my DSLR. Going for portability made more sense for […]

5:44 PM | Update on SOCG and ACM
I am happy to have an update on the SOCG/STOC colocation issue that arose last week.  Or, better said, Jeff Erickson has an update, the short summary of which is that it looks like there has now been some very useful clarification.  The concerns of the ACM apparently are limited to direct financial support, and the conferences can (formally) co-locate.  I encourage you to read the note on Jeff's blog from Paul, and let me echo Jeff's statement here: "Needless to say, this […]

4:52 PM | What the FAA Thinks of RC Aircraft, and Why it Matters
The past few weeks have witnessed developments that could spell the end of radio-control aeromodeling as we know it. In short, the Federal Aviation Administration (FAA) has claimed jurisdiction over certain RC activities. This move comes as part of the FAA’s attempt to grasp control of the rapidly expanding presence of Unmanned Aerial Systems (UAS) in the national airspace. What was once a relaxing pastime could soon be a punishable offense. Here's how that could affect you and your FPV […]

4:00 PM | In Brief: A Beginner's Guide to Drills and Bits
BoingBoing has been running a nice series of instructional guides to common workshop tools, written by maker Steve Hoefer. He started with a guide to wire strippers, and then a beginner's guide to hammers, and today has published an overview to the many different types of hand drills and bits. I like Hoefer's approach to explaining tools; his write-ups are primers are more about breath than depth, and point you in the right direction for a specific task at hand. Perfect for a beginner like me!

3:30 PM | Parallel Paths for Deep Learning and Signal Processing ?
This is a follow-up to this thread.Deep learning in Machine Learning stands for neural networks with many layers for the purpose of producing features that can eventually be used for classification. In image/signal processing, the generic idea is to acquire and decompose a signal along a family of (generally) known signals (bases in known/identified spaces). Simple machine learning techniques can then rely on the elements of that decomposition (the features in ML) to achieve the last step of a […]

7:40 AM | Bits to Atoms: Building the Millenbaugh Motivator, Part 4
Your patience has paid off--it’s time for the final print of the Millenbaugh Motivator! All the measurements have been made, a rough version has been completed, the final version has been modeled and prototypes printed. After three months of work, it was time to get this delivered to Adam. And that meant making a flight back out to San Francisco.For my previous prints, such as the Octopod and Jetcar builds, I’ve used the trusty Objet Connex500. It's a high-end polyjet printer that […]

7:20 AM | Adam's Mecha-Hand Posters are Now Shipping!
Hey everyone, we're pleased to let Premium Members know that we began shipping out the Mecha-Hand posters today. The prints arrived in our office and look fantastic--they're 24"x36" if you want to get a frame ahead of time. We had to approve the packing process, and are shipping them out in batches of a few hundred each. Once Will and I get back from PAX, we'll continue the shipping the rest of the posters a batch at a time, and hope to have all of them out for members who joined during the […]

7:05 AM | This Is The Best Wi-Fi Router
This post was done in partnership with The Wirecutter. Read the original full article below at TheWirecutter.comIf your laptop, smartphone, or tablet uses the latest wireless-AC networking technology and you’re shopping for a new router, you should get the Netgear R6250. The benefits of wireless-ac are great: super-fast performance that can be stronger at longer distances than wireless-n routers. More than 100 hours of combined testing and research led us to the $150 R6250, which boasts […]

5:00 AM | Yoshua Bengio"s view on Deep Learning
Following this entry, Yoshua Bengio just wrote the following on his Google+ stream (I have a added a few links and reshaped the text for clearer reading):There was an interesting debate on deep learning at Technion a couple of days ago: http://nuit-blanche.blogspot.fr/2014/08/is-deep-learning-final-frontier-and-end.html I wasn't there but I wished I had been to clarify a number of points. So I wrote this message to the members of the debate panel (sorry, it's pretty […]

10:42 PM | Who Invented Pointers, Amortized Complexity, And More?
Some algorithmic tricks were first invented in complexity theory Andrey Kolmogorov, Fred Hennie, Richard Stearns, and Walter Savitch are all famous separately; but they have something in common. Read on, and see. Today I wish to discuss some algorithmic tricks and show that they were initially used by complexity theorists, years before they were used […]

10:14 PM | New Article on arxiv on Equitability and MIC
We recently put on arxiv a new draft on "Theoretical Foundations of Equitability and the Maximal Information Coefficient".  This is some follow-on work to a paper that appeared in Science a couple of years ago, where we introduced the idea of equitability.  Essentially, in that Science paper (link to page where you can access the paper), we wanted a statistic that would give back, for samples from a noisy functional relationship, a score corresponding to the amount of noise (or, […]

A unique experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory called the Holometer has started collecting data that will answer some mind-bending questions about our universe – including whether we live in a hologram. Much like characters on a television show would not know that their seemingly 3-D world exists only on…Read more →

6:32 PM | Designing a Custom Arcade Cabinet in Sketchup
As soon as Norm and I decided to build an arcade cabinet, we ran into a problem: We didn't actually know how to build an arcade cabinet. We knew what we wanted, at least in general--a four-player MAME cocktail cabinet that could support fighting games and beat 'em ups and pretty much anything else we could throw at it. How hard could it be to find exactly what we wanted online, then replicate it at home? Turns out: Pretty hard.ArcadeDepot, one of the most popular sources for arcade kits, was […]

6:00 PM | Testing: Instagram's Hyperlapse App for iOS
Instagram today announced and released a new iOS video app called Hyperlapse. It was a pet project of Instagram engineers Thomas Dimson and Alex Karpenko, and impressed Instagram founder Kevin Systrom enough that the company developed it into a full-fledged app. Wired Design's Cliff Kuang has an exclusive story about the app's origins, if you're curious. But after a morning of testing, here's what you need to know about it.Hyperlapse is a time-lapse app for iOS, much like Studio Neat's […]

5:07 PM | Can we use games to control our mood?
Video games are very complex experiences. They involve paying attention to virtual objects, vehicles and characters; all working together to offer both a challenge and a narrative. As a result they provoke a wide range of emotions. Games can make us anxious and scared, but also relaxed. They can help change boredom into excitement, and sadness into happiness. They seem to be able to change how we feel. But how reliable are they? Can we use games to switch our emotions at will? Can we use them […]

11:41 AM | Advice to a Freshly Graduated Graduate Student
Yesterday, I asked Junjie where his code would eventually be available. Initially Junjie wanted me to post it on my google site since he did not have an internet presence. During our back and forth conversation, it became clear that letting others be the owner of one's intellectual work and accomplishments is not a good signal fresh graduates want to send to the rest of the world. If you are a graduate student who has put the work, your research production cannot be in the hand of others […]

11:39 PM | The Zoidberg Project in Pictures
Last week, we published the final installment to our Zoidberg Project with Frank Ippolito, capping off the series with Frank's walk through Comic-Con in his Jesus Zoidberg variant costume. Throughout the build, Frank supplied us with dozens of photos every week documenting every step of the build, many of which we published in Frank's build logs. Spread across multiple months, it's difficult to appreciate the artistry that transformed this sculpture from sketches and 3D renderings to the foam […]

10:45 PM | In Brief: USB "Condom" Protects Devices from "Juice Jacking"
Cory Doctorow of BoingBoing shares this crowdfunded USB dongle that acts as a protective barrier between your USB device and a potentially malicious charging station. The $10 USBCondom was funded on CrowdSupply earlier this year, and is now shipping and taking pre-orders for the next production run. It works by blocking the data pins on a USB connection, only allowing power to pass through to your device. As Doctorow points out, you can also buy a USB cable that does the same thing for $9.

9:38 PM | Making a B.F. Goodrich Mercury Mark IV Helmet, Part 1
When Adam commissioned us to make a hybrid NASA Mercury space program suit, we didn’t give much thought to the helmet or really any of the “hard parts” with the exception of the neck and wrist rings. We just figured that if anyone was interested in buying another suit, they would have to find a helmet on their own, and that we’d probably have to re-cast or find standalone MIG neck rings. Adam advised us they would be hard to find.But initial feedback from prospective […]
