3:24 PM | Drinking My Education.
Yesterday I wrote about not being good enough to be a professor of systems engineering. But if you’ve read this blog long at all, you know that I’ve wondered if, in different circumstances, I might have been. I don’t know. I’ll never know. I find myself, often, tempted to blame woes in life on my […]

11:00 AM | Rethinking environmental folklore
You’ve likely faced the question: “paper or plastic?” Clearly the paper bag is the better option, right? Or is it? In a TED Talk, Leyla Acaroglu has a challenge for us. She wants us to rethink our... -- Read more on ScientificAmerican.com

10:38 AM | Recent Developments in the Sparse Fourier Transform: A Fast DSP Chip and a faster GPS
A 0.75-million-point fourier-transform chip for frequency-sparse signals by Omid Abari, Ezz Hamed, Haitham Hassanieh, Abhinav Agarwal, Dina Katabi, Anantha P. Chandrakasan, Vladimir StojanovicApplications like spectrum sensing, radar signal processing, and pattern matching by convolving a signal with a long code, as in GPS, require large FFT sizes. ASIC implementations of such FFTs are challenging due to their large silicon area and high power consumption. However, the signals in […]

5:30 PM | Firing a shotgun to calculate the approximate value of π
This mathematics paper broadens the old definition of “a shotgun approach” to solving a problem: “A Ballistic Monte Carlo Approximation of π,” Vincent Dumoulin [pictured here], Félix Thouin, arXiv 1404.1499v2, April 8, 2014. (Thanks to investigator Marcus Sprenkel for bringing this to our attention.) The authors, at the University of Montreal, report: “We compute a […]

4:10 PM | Redesigned rotary movement for shoulder
I've moved the motor that rotates the robot's arm inside of the chest cavity to save space. The previous arm configuration was based off of one of my first tests for mounting the robot's arms which used a motor mounted in the arm. Mounting the motor inside of the robot's chest cavity will allow me to reduce the weight of the robot's arms for future versions.I'm currently modeling a new left arm for the robot which will incorporate more joints for an improved range of motion.

3:26 PM | Compressive classification and the rare eclipse problem
This is interesting !Compressive classification and the rare eclipse problem by Afonso S. Bandeira, Dustin G. Mixon, Benjamin RechtThis paper addresses the fundamental question of when convex sets remain disjoint after random projection. We provide an analysis using ideas from high-dimensional convex geometry. For ellipsoids, we provide a bound in terms of the distance between these ellipsoids and simple functions of their polynomial coefficients. As an application, this theorem […]

“Generally speaking, modeling the developmental trajectory for almost any intelligent task that a 2-year-old child can perform on a robot is a potential research topic for us.” - explains the website of the Developmental Robotics Lab at Iowa State University, US. As an example to help clarify the (somewhat ambiguous) statement above, see the lab’s […]

Ed Yong is one of the English language’s better science writers. He often weighs in on issues facing academia, in addition to reporting science. One of the biggest issues facing academia right now is the pipeline problem: too many PhDs are graduating compared with the number of professorships that will ever be available for them. […]

5:00 AM | Confidence Intervals and Hypothesis Testing for High-Dimensional Regression - implementation -
As we were discussing the release of an implementation of the Sparse PCA algorithm, Andrea mentioned to me the release of an R program for hypothesis testing with the Lasso:Confidence Intervals and Hypothesis Testing for High-Dimensional Regression by Adel Javanmard, Andrea MontanariFitting high-dimensional statistical models often requires the use of non-linear parameter estimation procedures. As a consequence, it is generally impossible to obtain an exact characterization of […]

In the past two weeks, I have been introduced as Mike’s spouse twice in professional settings. I usually view this as something akin to the Kiss of Death: the person receiving this news is likely to consider me an appendage to my spouse and therefore rather useless.  It’s not that I mind people know I […]

1:46 PM | A kind of thing that humans can learn during sleep
The industry devoted to “sleep learning” aside, it’s been unclear that people can learn much of anything while they are asleep. An experiment (by much the same team that later noted the phenomenon of contagious sniffing), says it has identified one kind of thing that people can indeed learn while they are asleep: “Humans can […]

1:58 AM | This title isn’t nearly innovative enough
I’ve been pondering a question…and asking a few people, as well. What do you consider innovative? In particular, I’m wondering if people say it is only innovative to have a new idea that no one has thought of before.  What about a different scenario: would you consider it innovative if you came up with a viable […]
