Here is what I found relevant this past week on the blogs and elsewhere:
* Two questions on the Compressive sensing LinkedIn group asking if anyone knew of a formulation for total variation minimization using the AMP (approximate message passing) algorithm?, or Identifying a good Metric for Comparison between various CS Reconstruction algorithms. That group has 1481 members, while the Advanced Matrix Factorization group has 292 members.
* Dustin goes deeper in explaining his recent paper on why Certifying the Restricted Isometry Property is Hard.
* Danny tells us about a synthetic large benchmark, Ensemble methods - a notable book by Elder and Seni, a KDD CUP Update and a KDD CUP 2012 Track 1 using GraphLab..* Bob writes about:
- Experiments with MOD
- A Concatenative Synthesis Patent Challenge?
- A missing step from the Method of Directions?
- Dictionary learning with the Method of Optimal Directions
- Theorem 10 of On polar polytopes and the recovery of sparse representations
- Computer Music Judges
* Greg talks about his Paper on the MIT Build a Radar Course that will be presented at the IEEE Radar Con 2012
* Finally, John talks about ICML: Behind the Scenes
