5:00 AM | Sparse recovery by means of nonnegative least squares - implementation -
Sparse recovery by means of nonnegative least squares by Simon Foucart, David KoslickiThis short note demonstrates that sparse recovery can be achieved by an `1-minimization ersatz easily implemented using a conventional nonnegative least squares algorithm. A connection with orthogonal matching pursuit is also highlighted. The preliminary results call for more investigations on the potential of the method and on its relations to classical sparse recovery algorithms.The implementation is […]

5:00 AM | disPCA: Improved Distributed Principal Component Analysis
Improved Distributed Principal Component Analysis by Maria-Florina Balcan, Vandana Kanchanapally, Yingyu Liang, David WoodruffWe study the distributed computing setting in which there are multiple servers, each holding a set of points, who wish to compute functions on the union of their point sets. A key task in this setting is Principal Component Analysis (PCA), in which the servers would like to compute a low dimensional subspace capturing as much of the variance of the union of […]

5:13 PM | Science Blogging Something Completely Different
For many science writers, the science blog post has come to epitomize the Monty Python phrase, "and now for something completely different." And if not something completely different, than at least something different in one way or another from your typical science news story, your typical opinion column or or your typical print feature story, among other science story formats. As you might know if you've been following me on Twitter, I've been conducting interviews with science bloggers […]

2:00 PM | Update: Greenwashing 7 - Simple Green
Way back when I followed a CBC Marketplace show and assessed their assessment of the products, I mentioned that I should buy and try one of them: Simple Green. Well, I did, and I forgot to post an update. So, here it is. I tried it out on a stubborn dirty spot that both "Scrub Free" and "Fantastik" barely touched, even with a lot of scrubbing. I followed the directions on the bottle: for tough
