Yann LeCun provided additional insight to the Signal Recovery from $\ell_p$ Pooling Representations entry. Go read it here.

Afonso Bandeira just sent me the following:

Hi Igor,First of all, congrats on the great blog!I noticed that you mentioned the Grothendieck problem a few days ago in your blog. I just wrote a blog post (about my work on a natural generalization of that problem) where I discuss that problem quite a bit. I thought you might want to take a look:Keep up the good work with your blog!Best,Afonso

Thanks Afonso. Afonso restarted his blog in full force since September, here is a longer list of entries from his blog:

- The little Grothendieck problem over O(d)
- A conjecture on the singular values of a Gaussian matrix
- How to build a dual certificate for Synchronization over Z_2
- The Angular Synchronization problem and a Cheeger Inequality
- The Johnson-Lindenstrauss Lemma
- Computing sparse quadratic models in DFO
- Proof of Landau’s conditions for the Hankel transform
- Landau’s necessary density conditions for the Hankel transform
- Approximation Algorithm for Max-Cut (SDP relaxation)
- Cheeger Inequality and Spectral Clustering
- Diffusion Maps and Clustering on Graphs

I did a small survey on the last 100 posts that received either more than a 1000 page views (a certain amount were just below that threshold) or received more than 8 Google+1, here there are below. I like the fact that the Sunday Morning Insight series does generate some readership and/or appreciation:
