Publications Update

After a long delay I managed to update my publication list! Here are the updates:

  1. The Universal Scalar Quantization paper has appeared in Trans. Info. Theory [1]. The entry is updated with bibliographic info and accurate bibtex.
  2. I presented three papers at ICASSP 2012 in Kyoto: on Depth Sensing [2], on a Compressive Phased-Locked Loop (PLL) [3] and on Pan-sharpening using Dictionary Learning [4]. The papers are now uploaded. I also realized that ICASSP 2012 has not appeared in IEEE Xplore yet!
  3. We have a new journal submission on our sparsity-constrained optimization work [5]. Sohail has put up a nice page with description and code on the algorithm.
  4. I updated entries of older papers to include the links to the corresponding proceedings page and the doi in the bibtex (where available).

I hope you find these useful! Please let me know if I missed something!

Binary Stable Embeddings for 1-Bit CS

Our paper on 1-Bit compressive sensing and binary stable embeddings has now been updated [1]. You can find it on arXiv or here. The new version strengthens some of the results and incorporates discussion on how our work relates to recent activity in the area since it first appeared. It turns out that 1-bit CS is a very rich and exciting topic, with many connections with diverse topics such as locality sensitive hashing and the logistic regression. You can find more details on 1-bit CS and the related topics on my research pages and on the Rice webpage dedicated to the topic.
