5:00 PM | Introducing Our Newest Columnist: Patrick Norton!
Howdy! My name is Patrick Norton. If you're a regular visitor at Tested, you might have seen me join Norm and Will on This Is Only A Test and the first Lego with Friends in the past few weeks. And, beyond showing up for several Octoberkasts for the 2AM to 5AM shift bearing a giant box of Bob’s Donuts and weird stories about wrenching on trucks at the Baja 1000, you might be wondering just who the heck I am.Mostly, I’m a geek. I review products, from headphones to gaming PCs, answer […]

3:11 PM | Learning Co-Sparse Analysis Operators with Separable Structures
Matthias just sent me the following:Dear Igor,We just finished work on a paper which discusses learning of cosparse analysis operator with separable structures. The main topics are the derivation of bounds on the sample complexity of analysis operator learning algorithms and the discussion of a learning procedure based on geometric stochastic gradient descent. A preprint is available at http://arxiv.org/abs/1503.02398We thought that this paper might be of interest to the readers of your Nuit […]

2:32 PM | No Pressure
Last night, I was talking to a few folks in the audience of the Paris Machine Learning Meetup and learned something amazing from one of them. The paper is likely to come out within the next few weeks. I haven't seen the paper, just some of the figures, but based on that alone and much like a previous instance (in a different domain) it is likely that there will be a "before" and "after" this paper.Stay tuned.  Join the CompressiveSensing subreddit or the Google+ Community and post […]

8:56 AM | A Compendium of Clean Graphs in R
[This is a guest post by Eric-Jan Wagenmakers and Quentin Gronau about the RGraphCompendium] Every data analyst knows that a good graph is worth a thousand words, and perhaps a hundred tables. But how should one create a good, clean graph? In R, this task is anything but easy. Many users find it almost impossible […]

5:00 AM | VLSI Design of a Monolithic Compressive-Sensing Wideband Analog-to-Information Converter (and other FPGA implementations)
When we talk about compressive sensing implementations, we seldomly talk about reconstruction solvers. Back in July of last year, Chris Studer was in town and did a presentation at this meeting organized by Patricia Desgreys and Laurent Daudet entitled "Acquisition/Echantillonnage comprimé : quelles réalisations/applications pratiques ?". There, he said some interesting things about empirical knowledge and reconstruction solvers and I am still trying to get a more official answer […]

6:40 PM | 2015 EAPLS Board member elections
EAPLS, the European Association for Programming Languages and Systems, aims to stimulate research in the area of programming languages and systems. Formally inaugurated in 1996, it provides a forum for researchers across the domain, working with related organisations and industry to initiate scientific events and stimulate the exchange of ideas, as well as raising funds, […]

6:00 PM | Conjoined Wings: Aviation’s Pullers, Parasites and Piggybacks
Even in the early pioneering days of aviation, engineers recognized the potential for teamwork among aircraft. By lashing two or more aircraft together, the combined machines could often accomplish things that neither vehicle was capable of on its own. It’s the wild blue yonder’s embodiment of the whole being greater than the sum of its parts.This concept of mating together different aircraft is one that has persevered even as the art of aeronautics has constantly evolved. Whether […]

4:00 PM | Biomimetics: Learning about Camouflage from Cuttlefish
Few animals in the world are better at camouflaging themselves then the cephalopod. A family of ocean-going invertebrates that include the octopus, the squid, and the cuttlefish, these squishy little guys are better than anybody at disappearing into their surroundings. And that makes them the ideal candidates for biomimicry.In Woods Hole, Massachusetts, biologist Roger Hanlon is focused on puzzling out the cellular systems that make quick color changes possible. This is done both inside the lab […]

3:51 PM | Extremely small probabilities
One objection to modeling adult heights with a normal distribution is that the former is obviously positive but the latter can be negative. However, by this model negative heights are astronomically unlikely. I’ll explain below how one can take “astronomically” literally in this context. A common model says that men’s and women’s heights are normally […]

3:44 PM | The ultimate physical limits of privacy
Somewhat along the lines of my last post, the other day a reader sent me an amusing list of questions about privacy and fundamental physics.  The questions, and my answers, are below. 1. Does the universe provide us with a minimum level of information security? I’m not sure what the question means. Yes, there are […]

12:07 PM | Atavachron
In the Star Trek episode “All Our Yesterdays” the people of the planet Sarpeidon have escaped into their past because their sun is about to become a supernova. They did this via a time machine called the Atavachron. One detail of the episode has stuck with me since I first saw it many years ago: although people can go back […]

5:00 AM | Ernie Esser's Passing and Legacy
Felix just sent me the following last night:Dear Igor, It is my sad duty to let our community know that Ernie Esser passed away yesterday from complications of pneumonia on his trip back from Europe. Ernie was a very active member of the compressive sensing and optimization communities. Only very recently Ernie made I think a major contribution to blind deconvolution Ernie Esser, Tim T.Y.

1:00 AM | HTC Vive vs. Oculus Crescent Bay: My 10 VR Takeaways
Palmer did it. Virtual reality isn’t vaporware. It’s going to change the way we think about home gaming and media, and consumer-ready products are coming out before the end of the year. That’s super exciting, but also a little bit scary. Holiday 2015 is still nine months away, and there’s a lot we still don’t know about when it comes to VR. There’s a language that we, even as as enthusiasts, have to learn when talking about virtual reality products and […]
