3:30 PM | EMaC : Robust Spectral Compressed Sensing via Structured Matrix Completion - implementation -
I love it when there is an implementation, it gets even more interesting when the paper shows phase transitions. Quite simply, the authors send the signal that while theoretical developments are OK, the only way to really compare all these solvers is to show how each of those perform as regards to the acid test of the sharp phase transitions. Here is a new example of that: Robust Spectral Compressed Sensing via Structured Matrix Completion by Yuxin Chen, Yuejie ChiThe paper […]

2:31 PM | Letters of Support.
So for the R03 I’m writing, I’ll get letters of support from all the key personnel and my department head, etc.. But I wonder about other letters. When I wrote my first R03eq grant at my former employer, I got a local famous person in a closely-related field to write me a letter that basically […]

11:47 AM | Springtime arm mockup
In addition to a pair of new hands for the robot, I am also experimenting with a new design for the arm. At the moment I have created a mock-up in cardboard so that I can make changes easily. The new arm adds shoulder and wrist joints that were not previously included in the design.Many thanks to +Western New England University for donating the pens which will be used to make two new hands for the robot. For anyone interested in how the pens will be used checkout my original post […]

5:00 AM | Low-Rank Modeling of Local k-Space Neighborhoods (LORAKS): Implementation and Examples for Reproducible Research
Justin Haldar just sent me the following:Hi Igor,Wanted to let you know that we've finally put out the public release of the LORAKS code (that you featured on Nuit Blanche back in December). There is a technical report that describes the implementation and walks through all of the examples included with the code available here:http://sipi.usc.edu/reports/abstracts.php?rid=sipi-414The tech report (and the corresponding demo code) build on the original published LORAKS paper, showing several […]

7:49 PM | Grant Decisions.
It’s an R03. I’m not writing the R18. I’d love to, but frankly, there’re a couple of good reasons not to. First and foremost, I don’t have sufficient preliminary data/work to justify the government dumping $750,000 over three years in my lap. The R03 is only $100,000 over two. Second, my department’s entire grant history […]

5:00 AM | Random forests with random projections of the output space for high dimensional multi-label classification
It started in 2009 when John Langford and colleagues noted that label vectors were sparse and that using techniques of compressive sensing one could reduce learning in large dimensional space.

10:57 AM | Sunday Morning Insight: Why You Should Care About Phase Transitions in Clustering
Figure from [1]In the Advanced Matrix Factorization page, I have no listing for the phase transition section of the spectral clustering or its nonlinear cousin subspace clustering. Little did I know that Suresh Venkatasubramanian (from the GeomBlog fame) has written about it in his essay on clustering. In particular, he wrote this interesting entry entitled: Choosing the number of clusters III: Phase Transitions where he draws a connection with statistical […]

1:36 AM | Best of mcguire: ruthless simplicity
A few days ago, the article Boring Systems Build Badass Businesses appeared on Hacker News. In one comment, idlewan wrote, "It's not about the end result, it's about using better tools to get to it," arguing the case for specialized tools, in this case some CSS compiler. In response, mcguire wrote: How old is your CSS compiler? After gaining a fair amount of experience with various technologies over the years (by which I mean, getting burned (especially by things that seem wonderful and then […]

5:01 AM | It's Algorithmic Indulgence for the Masses (or the niche market)
Introducing the latest addition to the Synthetic Daisies blog: Popular Algorithmics. Popular Algorithmics (a takeoff on Popular Mechanics) is a collection of posts originally presented as a series on Tumbld Thoughts. Each entry is a take-off on an established algorithmic approach from the scientific literature. Of particular interest are lesser known algorithmic approaches from the standpoint of both theory and application.
