4:04 PM | Sketching and Embedding are Equivalent for Norms
It was on my list of "to feature" preprint but it looks like Ilya Razenshteyn has written a detailed blog post about it. Here is the paper: Sketching and Embedding are Equivalent for Norms by Alexandr Andoni, Robert Krauthgamer, Ilya RazenshteynAn outstanding open question [sublinear.info, Question #5] asks to characterize metric spaces in which distances can be estimated using efficient sketches. Specifically, we say that a sketching algorithm is efficient if it achieves constant approximation […]

2:50 PM | The wondrous Walter Pitts and his friends and collaborators
Amanda Gefter, writing in Nautilus, profiles Walter Pitts: Thus formed the beginnings of the group who would become known as the cyberneticians, with Wiener, Pitts, McCulloch, Lettvin, and von Neumann its core. And among this rarified group, the formerly homeless runaway stood out. “None of us would think of publishing a paper without his corrections […]

12:54 PM | Analyzing cricket’s batting legends – Through the mirage with R
In this post I do a deep dive into the records of the all-time batting legends of cricket to identify interesting information about their achievements. In my opinion, the usual currency for batsman’s performance like most number of centuries or highest batting average are too gross in their significance. I wanted something finer where we […]

6:00 AM | Signal Recovery from Pooling Representations - implementation -
Continuing on Nonlinear Compressive Sensing and related matter, we mentioned it recently in Some thoughts on invertibility: Signal recovery from Pooling Representations, Determination of Nonlinear Genetic Architecture using Compressed Sensing   but today we have an implementation of the algorithm featured in that important. Arthur actually made good on his promise :-). Thanks Arthur! Here is the paper: Signal Recovery from Pooling Representations by Joan Bruna, Arthur Szlam, Yann […]

3:15 AM | Mapping a Social Network
Today, I am going to show you how to map a social network using NodeXL and Gephi. These are open source and free software packages that you can install on your PC (NodeXL runs only on PC) or Mac (Gephi runs on PC and Mac). There are many reasons you might want to map a social network. You may want to see if a particular group of Twitter users all talk to each other, or whether they form groups that talk among...

4:30 PM | S-AMP for Non-linear Observation Models
AMP for nonlinear acquisition measurement systems. S-AMP for Non-linear Observation Models by Burak Çakmak, Ole Winther, Bernard H. Fleury Recently we extended Approximate message passing (AMP) algorithm to be able to handle general invariant matrix ensembles. In this contribution we extend our S-AMP approach to non-linear observation models. We obtain generalized AMP (GAMP) algorithm as the special case when the measurement matrix has zero-mean iid Gaussian entries. Our derivation […]

6:00 AM | Self-Calibration and Biconvex Compressive Sensing
Three concepts met and phase transitions were had:: Self-Calibration and Biconvex Compressive Sensing by Shuyang Ling, Thomas Strohmer The design of high-precision sensing devises becomes ever more difficult and expensive. At the same time, the need for precise calibration of these devices (ranging from tiny sensors to space telescopes) manifests itself as a major roadblock in many scientific and technological endeavors. To achieve optimal performance of advanced high-performance sensors one […]
