1:57 PM | Deep Sadness.
I will not condemn rage. I will not condemn lashing out in the face of an implacable process that protects the powerful and degrades the vulnerable. I will not condemn generations of grief and injustice when it is given voice in flames and shattered glass. I simply cannot understand. Certainly, I can diagram and dissect […]

Richard Conniff writes, in the Strange Behaviors blog: Look, Look, Look! A Lesson in the Art of Seeing I’ve never been particularly fond of the nineteenth century naturalist Louis Agassiz, probably due to a time I was sitting in a library at Harvard and holding in my hands a letter he had written to his […]

6:00 AM | Spectral Clustering of Graphs with the Bethe Hessian - implementation -
To be filed in the Matrix Factorization Jungle page in the clustering section and its attendant phase transitions.Spectral Clustering of Graphs with the Bethe Hessian by Alaa Saade, Florent Krzakala, Lenka ZdeborováSpectral clustering is a standard approach to label nodes on a graph by studying the (largest or lowest) eigenvalues of a symmetric real matrix such as e.g. the adjacency or the Laplacian. Recently, it has been argued that using instead a more complicated, non-symmetric and […]

10:32 PM | Nuclear Norm Minimization via Active Subspace Selection
  Nuclear Norm Minimization via Active Subspace Selection by Cho-Jui Hsieh, Peder A. OlsenWe describe a novel approach to optimizing matrix problems involving nuclear norm regularization and apply it to the matrix completion problem. We combine methods from non-smooth and smooth optimization. At each step we use the proximal gradient to select an active subspace. We then find a smooth, convex relaxation of the smaller subspace problems and solve these using second order methods. We apply […]

3:55 PM | Hot dogs (canines) with hops
Dogs (Canis lupus familiaris) should if possible avoid hops (Humulus lupulus). For dogs ingesting hops can, and often do, overheat to an alarming, sometimes life-threatening degree. *see note. The physiological pathways involved are as yet  poorly understood  unknown. See: Toxicology Brief: Hops Make Dogs Hot, Veterinary Technician, August 2013 (Vol 34, No 8). * Note: […]

12:49 PM | Run Run Run Run.
I ran the Philadelphia half marathon yesterday with BB, and we set our new personal record.  A little less than two hours and fifteen minutes. Not shabby for 13.1 miles, on a course which had a couple of pretty decent hills. And for having a strain in my lower abs or groin (not sure which, […]

6:00 AM | Randomized Interpolative Decomposition of Separated Representations
Random projections with tensors.Randomized Interpolative Decomposition of Separated Representations by David J. Biagioni, Daniel Beylkin, Gregory BeylkinWe introduce tensor Interpolative Decomposition (tensor ID) for the reduction of the separation rank of Canonical Tensor Decompositions (CTDs). Tensor ID selects, for a user-defined accuracy \epsilon, a near optimal subset of terms of a CTD to represent the remaining terms via a linear combination of the selected terms. Tensor ID can be used as […]

Here are a few new (or new to me) papers that are evolution-related from my reading queue. There is a loose theme to these papers (indicated in the title of this post). I will give you my impressions and insights as the post proceeds.Varieties of uni- and multicellular relationships amongst different species of green algae. COURTESY: Figure 1 in [1].1.

1:52 AM | Lexile ludification
A while back, I wrote about our first experience with lexile ranges.  The short story is that lexile ranges are indicators of reading levels that are determined by sentence length and word frequency.  While they may be a useful tool to picking out books for children, they don’t at all address the complexity of themes […]

4:41 PM | Sunday Morning Insight: It's Complicated...On Games, NP-hardness, Grothendieck, Learning and Friends.
At the last Machine Learning meetup in Paris, someone (I believe it was Vincent Guigue ) made the comment that "not" was a relatively powerful feature for detecting sentiment analysis in a written paragraph. Some of us wondered if the same was really true in French (it does not look like it is). Clearly it opens another line of thought, if you have a model that works well in English, because it has been able to put the right importance on the "not" feature, will that model be as efficient […]

8:01 PM | A Happy Faux-Academic.
So, three great pieces of news this week, relating to my pretend academic pursuits. First, I got stellar reviews back for another paper, including one reviewer who recommended that the paper be published “as is” with no revision. I have never had so fine a review. Reviewer three, as usual, was jacked up on imitation […]

7:06 PM | Friday fun: The Rubik’s Cube
As a freshman in college, I remember going to a toy and puzzles shop in Old Town Pasadena.  I became engrossed in a 3D puzzle display.  You know the horseshoes connected with chains that have a metal ring?  That’s the kind of puzzles in the display.  I spent an hour and a half looking for […]

9:03 AM | Provable Bounds for Learning Some Deep Representations
Following up on this entry, here are some headways connecting the deep architectures of some neural networks with random matrix theory and some of the findings in compressive sensing. From the paper:In fact our result that a single layer of our generative model is a sparse denoising autoencoder can be seen as an analog of the fact that random matrices are good for compressed sensing/sparse reconstruction (see Donoho (Donoho,2006) for general matrices and Berinde et al. (Berinde et al., 2008) […]
