3:00 PM | Optimization of Convex Functions with Random Pursuit - implementation -
Optimization of Convex Functions with Random Pursuit by Sebastian U. Stich, Christian L. Müller, Bernd GärtnerWe consider unconstrained randomized optimization of convex objective functions. We analyze the Random Pursuit algorithm, which iteratively computes an approximate solution to the optimization problem by repeated optimization over a randomly chosen one-dimensional subspace. This randomized method only uses zeroth-order information about the objective function and […]

5:00 AM | Maximum Entropy Hadamard Sensing of Sparse and Localized Signals - implementation -
Maximum Entropy Hadamard Sensing of Sparse and Localized Signals by Valerio Cambareri, Riccardo Rovatti, Gianluca SettiThe quest for optimal sensing matrices is crucial in the design of efficient Compressed Sensing architectures. In this paper we propose a maximum entropy criterion for the design of optimal Hadamard sensing matrices (and similar deterministic ensembles) when the signal being acquired is sparse and non-white. Since the resulting design strategy entails a […]

3:01 PM | Improving Pacific Biosciences' Single Molecule Real Time Sequencing Technology through Advanced Matrix Factorization ?
If you watched Elaine Mardis' Videos and Slides: Next-Generation Sequencing Technologies you noted that in order to produce complete genomic data, sequencing technology needs long read technology (also called 3rd generation sequencing technology) like the Pacific BioSciences SMRT or the nanopore technology. In fact, any advances in medical techology will come from dropping the price of these instruments to even lower prices than what we currently seem to reach. One of the issue with long […]

2:04 PM | “… yet the world it describes is a mess”
“Physics may aim for simplicity, yet the world it  describes is a mess.” That’s the start of John Cartwright’s article, “Roll Over, Bolzmann,” in the magazine Physics World. It tells the story of Tsallis entropy: Our definition of entropy is expressed by one of the most famous formulae in physics, and dates back over a century […]

2:03 PM | The smell of macaroni [part 2]
Q. How do Macaroni penguins smell? A. Pretty bad. For example, Lindeboom [1984] estimated that 220 kg NH3-N was volatilized daily from a rookery on Subantarctic Marion Island occupied by 350000 macaroni penguins, and reported that the odor was apparent up to 10 km from the source. More details can be found here. Previous article: […]

Two instance of CS Hardware today:Compressive Imaging and Characterization of Sparse Light Deflection Maps by Prasad Sudhakar, Laurent Jacques, Xavier Dubois, Philippe Antoine, Luc JoannesLight rays incident on a transparent object of uniform refractive index undergo deflections, which uniquely characterize the surface geometry of the object. Associated with each point on the surface is a deflection map which describes the pattern of deflections in various directions and it tends to […]

5:52 PM | A Review of Progress.
Sometimes I go look at old copies of my CV to see the professional progress I’ve made. It’s stupid and vain, yes. But it’s meaningful to me to see how over the course of two or three years, I’ve increased my publication and grant output, I’ve changed positions and added invited lectures, etc.. I feel […]

3:30 PM | Videos and Slides: Next-Generation Sequencing Technologies - Elaine Mardis (2014)
Last time I mentioned Elaine Mardis videos giving a summary of next generation sequencing the video shot up and garnered more than 127,893 viewers. Coincidence ? I think not :-)Here is the new survey on Next Generation Sequencing where she talks about the current PacBio and Nanopore technology add-ons to the lab. I note the biology people liking the term "massively parallel" sequencing. Anyway, those third generation technologies are very interesting because instead of cutting DNA strands in […]

1:55 PM | Does chewing gum improve our mind and our productivity?
For advocates of chewing gum in school, if there are any, the past decade of research has brought data, and perhaps hope. A project called The Effects of Gum Chewing on Math Scores in Adolescents studied the mathematics grades and test scores of 53 teenage students who chewed gum and 58 who did not. Craig Johnston of the Baylor College of […]

1:48 PM | A three-minute 24-second struggle with the laws of physics
This video, 3:24 in duration*, shows a struggle to insert one object into another. It’s a struggle against some known, but perhaps not fully understood, laws of Newtonian physics. It is also perhaps an illustration of the Dunning-Kruger effect. * give or take a second BONUS: The 2000 Ig Nobel Prize for psychology was awarded to David Dunning of […]

5:00 AM | A compressed sensing perspective of hippocampal function
This is a theory but the main question really is: how do we go using fMRI and similar technology to figure out if this is really what is going on ? Food for thought.A compressed sensing perspective of hippocampal function by Panagiotis C. Petrantonakis and Panayiota PoiraziHippocampus is one of the most important information processing units in the brain. Input from the cortex passes through convergent axon pathways to the downstream hippocampal subregions and, after being appropriately […]
