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.

3:47 PM | High Performance Agent-Based Modeling in Repast HPC
High Performance Agent-Based Modeling in Repast HPCJohn T. Murphy, ArgonneMay 01, 2014Argonne TCS Building 240, Rm 5172Abstract:  Repast HPC is a platform for creating agent-based models (ABMs) in any high-performance computing environment that implements parallelism using MPI. Repast HPC provides a simple framework in which users can construct models without knowledge of MPI or other low-level details of parallel computing, and has extended the power of HPC to a wide range of users in the […]

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 […]

3:00 PM | In Brief: Designing the Ultimate Toy Gun
Ever wonder how the research and development divisions of massive toy companies operate? This FastCo Design profile of Mattel's new BOOMco line of toy guns details the three-year process Mattel researchers and prototypers journeyed to produce a product line to challenge Habro's Nerf (that design story told here by Wired). Mattel, known for its Hot Wheels cars and Barbie dolls, wants a share of the estimated $500 million toy blaster market (they already bought LEGO competitor Mega to fight in […]

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 […]

2:15 PM | Saturday Morning Video: Seth Lloyd, Quantum algorithms for supervised and unsupervised machine learning
Guillaume Palacios's presentation ( The D-Wave “Quantum Computer” Myths and Realities) at the recent Paris Machine Learning meetup got me thinking that this Quantum Computer might not all PR after all. It turns out that Google Tech Talks just released a video of Seth Lloyd on the subject of Quantum Machine Learning. At around 30 minutes, Seth describes the encoding of information from a CD into a Quantum state in a set up that parallels the single pixel camera. Here […]

7:09 PM | Tested: SaneBox Email Prioritization
Email has a unique problem. In the beginning, when the Internet was new, email’s general usefulness increased as each new person created an account. It was inexpensive, relatively easy to use, and faster than the alternative. But email had a fatal flaw baked in, it was designed for use on a network where every node was trusted. For a while, the general guidelines that evolved from users for acceptable behaviors on the service were good enough. But as more people connected to the service […]

4:14 PM | 24 Hours with the Acer Iconia A1 830
We’ve recently got our hands on the latest tablet from Acer.  It’s been released quietly and without the usual fanfare of PR promotion but don’t let that fool you into thinking that this is an insignificant device.  What is this device that we speak of… well it’s an 8″ tablet that looks VERY similar to […]

10:05 AM | Is There Anything Beyond Quantum Computing?
So I’ve written an article about the above question for PBS’s website—a sort of tl;dr version of my 2005 survey paper NP-Complete Problems and Physical Reality, but updated with new material about the simulation of quantum field theories and about AdS/CFT.  Go over there, read the article (it’s free), then come back here to talk about it if […]

9:55 AM | Sparse PCA: Covariance Thresholding and an AMP based approach
No implementation yet, but new ways of going about the Sparse PCA problem. I will be adding the following figure to the phase transition figure in the Advanced Matrix Factorization Jungle page for the Sparse PCA paragraph. As I mentioned in slide 13 of this recent ML Meetup presentation, to the untrained eye, sparse PCA is a solved problem, but the back story is a little bit more complex as related in the first paper: ....Over the last ten years, a significant effort […]

7:17 AM | Behind the Scenes at Kernerworks' Workshop
What do special effects veterans do when Hollywood relies increasingly less on practical effects and more on computer generated imagery? The effects experts at Kernerworks (who have worked with Jamie and Adam in the past) turned their fabrication experience into developing and building realistic trauma mannequins the military to train field medics. These robots not only behave realistically to simulate injuries, they look incredibly lifelike as well--some even have the capability to spurt […]

6:46 PM | Video game technology. Part 2 of 3: The HD Experience.
  claimtoken-534595084c47dOne of the most recent advances in entertainment technology has been the switch from standard resolution to High Definition. The change has affected not only displays but also the complexity of the media produced. Most TV shows, movies and video games are now made in this format. The capacity to offer higher resolution images even became a powerful weapon in the last version of the console wars. The technology has been so well received by the public that Ultra HD […]
