11:07 PM | A Science Journalist’s Chances
Frank Nuijens, @FrankNu on Twitter, recently pinged me in a tweet featuring an infographic that one of his Masters of Science Communication students created after reading my EMBO Reports article on the future of science journalism, An Explosion of Alternatives. Intrigued, I got in touch with the student, Benjamin Mul, to ask if he could talk to me about his graphics, shown below. Frank is a science journalist and founder of ScienceOnline Leiden, the Dutch community of people communicating […]

11:01 PM | The Map of the Cat, the Hair of the Dog, and Other Metaphors and Descriptors
What's in a set of descriptions, or a set of metaphors for that matter? Quite a bit or very little, depending on whether or not you are working in your area of specialty. Richard Feynman once (and to the great consternation of neurophysiologists within earshot) referred to a feline brain atlas as the “map of the cat” (not to be confused with Arnold’s Cat Map).Recurrent cats! But what about its brain?This parable, of course, speaks to the role of jargon in science. I am […]

5:00 AM | Generalized Low Rank Models - implementations in Julia and Spark -
Here is a large installment of Advanced Matrix Factorization instances. The codes are also available in Julia and Spark (a sign of things to come ?)Generalized Low Rank Models by Madeleine Udell, Corinne Horn, Reza Zadeh, Stephen Boyd Principal components analysis (PCA) is a well-known technique for approximating a data set represented by a matrix by a low rank matrix. Here, we extend the idea of PCA to handle arbitrary data sets consisting of numerical, Boolean, categorical, ordinal, and other […]

5:00 AM | Coreset and PCA: Distributed k-Means and k-Median Clustering on General Topologies - implementation -
Distributed k-Means and k-Median Clustering on General Topologies by Maria Florina Balcan, Steven Ehrlich, Yingyu LiangThis paper provides new algorithms for distributed clustering for two popular center-based objectives, k-median and k-means. These algorithms have provable guarantees and improve communication complexity over existing approaches. Following a classic approach in clustering by [13], we reduce the problem of finding a clustering with low cost to the problem of finding a coreset of […]
