1:15 AM | Grand unification of mathematics
Greg Egan’s short story Glory features a “xenomathematician” who discovers that an ancient civilization had produced a sort of grand unification of their various branches of mathematics. It was not a matter of everything in mathematics collapsing in on itself, with one branch turning out to have been merely a recapitulation of another under a different […]

6:06 PM | Abstract for "collège doctoral" seminar at IFPEN, March 2015
A while back, Laurent Duval kindly asked me to do a presentation at the "collège doctoral" seminar at IFPEN at the end of March.  Based on my co-hosting of the Paris Machine Learning meetup and the themes covered on Nuit Blanche, I (foolishly ?) decided to say yes. Here is my first (and probably last) draft abstract (so now it's public, I cannot walk away from this :-)Title: "Ca va être compliqué": Islands of knowledge, Mathematician-Pirates and the Great […]

1:08 PM | Kronecker PCA Based Robust SAR STAP
Using a Kronecker decomposition from a sample covariance matrix to remove noise. Interesting ! Kronecker PCA Based Robust SAR STAP by Kristjan Greenewald, Edmund Zelnio, Alfred O. Hero III In this work the detection of moving targets in multiantenna SAR is considered. As a high resolution radar imaging modality, SAR detects and identifies stationary targets very well, giving it an advantage over classical GMTI radars. Moving target detection is more challenging due to the "burying" of […]

12:35 PM | Natural optima occur in the middle
Akin’s eighth law of spacecraft design says In nature, the optimum is almost always in the middle somewhere. Distrust assertions that the optimum is at an extreme point. When I first read this I immediately thought of several examples where theory said that an optima was at an extreme, but experience said otherwise. Linear programming (LP) says […]

11:45 PM | New Heapable Subsequence Paper
In the "only a dozen people could care about this category"...About 4 1/2 years ago, I posted about a paper we had put up on the arxiv about Heapable Sequences and Subsequences.  The basic combinatorial structure we were looking at is a seemingly natural generalization of the idea of Longest Increasing Subsequences.  Say that a sequence is heapable if you can sequentially place the items into a (binary, increasing) heap, so each new item is the child of some item already in the […]

9:47 PM | Memrefuting
(in which I bring this blog back to the “safe, uncontroversial” territory of arguing with people who think they can solve NP-complete problems) A few people have asked my opinion about “memcomputing”: a computing paradigm that’s being advertised, by its developers, as a way to solve NP-complete problems in polynomial time.  According to the paper Memcomputing NP-complete problems […]

5:00 PM | “MTD” is misleading
Dose-finding trials of chemotherapy agents look for the MTD: maximum tolerated dose. The idea is to give patients as much chemotherapy as they can tolerate, hoping to do maximum damage to tumors without doing too much damage to patients. But “maximum tolerated dose” implies a degree of personalization that rarely exists in clinical trials. Phase I […]

4:00 PM | The Packard Merlin: How Detroit Mass-Produced Britain’s Hand-Built Powerhouse
Few engines throughout history have achieved a near mythical status among its admirers. Fewer still can share credit for the rescue of an entire nation. Perhaps only the Rolls-Royce Merlin engine can claim both distinctions. During the Battle of Britain, it was the Merlin that powered the Royal Air Force Hurricanes and Spitfires that were England’s only effective defense against German air attacks. With the battle won, and the engine’s reputation thus established, the Merlin would […]

2:40 PM | Decide what to abandon
Sometimes it’s rational to walk away from something you’ve invested a great deal in. It’s hard imagine how investors could abandon something as large and expensive as a shopping mall. And yet it must have been a sensible decision. If anyone disagreed, they could buy the abandoned mall on the belief that they could make a […]

Simple Random Number Generation is a random number generator written in C# based on George Marsaglia’s WMC algorithm. Finding probability distribution parameters from percentiles Numerical computing Avoiding […]

11:52 AM | SwissLeaks: the map of the globalized tax evasion
HSBC “Swiss Leaks” data shared by the International Consortium of Investigative Journalists reflect the globalization of tax evasion. While billions of dollars are inconceivable, mapping the origin of bank account holders allows an overview. This map is only a small contribution to the understanding of the Swiss Leaks data: Why this map? This map does voluntary not strictly stick to the geographical reality. It is a response to too many maps […]

7:59 AM | One Body Problems
It's hiring season, and we've all heard about two-body problems.But you may not have heard of the one-body problem:Is the place a single person takes a job in likely to have enough other single people around to facilitate searching for a partner ? I was 'spoken for' before I even finished my Ph.D, and never had to deal with this (rather, I had to work with the more traditional (ha!) two-body problem).

8:28 PM | The Best $500 TV You Can Buy Today
This post was done in partnership with The Wirecutter, a list of the best technology to buy.Read the full article below atTheWirecutter.comIf I were looking for a good, inexpensive, 50-inch TV, I’d get the Vizio E500i-B1. It has above-average picture quality—better than many more expensive models—with impressively dark blacks (a rarity in this price range of LCD), bright whites, decent motion resolution, and reasonably accurate colors. It also consistently gets top marks from […]

6:00 PM | In Brief: Why M&Ms are the Perfect Space Snack
Smithsonian magazine has a fun little feature about the history of chocolate in the space program. Chocolate has been a choice treat for cosmonauts and astronauts since the very first manned space flights, but has travelled in many different forms: tubed sauce, pudding, brownies, and of course, M&Ms. We were privileged to be able to see some of these freeze-dried and vacuum-sealed snacks during our visit to JSC in 2013. I can neither confirm nor deny that I have a sealed package of space […]

4:24 PM | On an optimal use of tags: CS, MF, ML, implementation, AMP and BlindDeconvolution and more....
It has come to my attention that I may not be doing an optimal job at providing the right tag for the right blog entry. In particular, I am sometimes not putting the most appropriate label and while putting another less used one. For this reason, I'll try to be consistent with regards to certain labels and subjects areas (you are welcome to let me know about tag failures and if specific tags ought to be added, this specific blog entry has been tagged with all these tags in order to let […]

12:20 PM | Perl regex twitter account
I’ve started a new Twitter account @PerlRegex for Perl regular expressions. My original account, @RegexTip, is for regular expressions in general and doesn’t go into much detail regarding any particular implementation. @PerlRegex goes into the specifics of regular expressions in Perl. Why specifically Perl regular expressions? Because Perl has the most powerful support for regular […]

8:02 AM | Why I Built Robotic Racing Spiders
When Evernote approached Adam and me and offered to support us in building anything we wanted, I suggested we make something that would never otherwise get made. Something that was unusual, that nobody in their right mind would take the trouble to do. Something I would build, just because I can!And the first thing that came to mind was to build big spiders that would be super fast and use a tendon-like system to pull the legs around. I would use synthetic fibers that were ultra light but […]
