1. Fill in the Blanks: Using Math to Turn Lo-Res Datasets Into Hi-Res Samples
An interesting article from Wired about Compressive Sensing. For more details see Igor’s page . I don’t claim to understand CS fully but i guess I know the major ideas. CS is a exciting field and what it does borders on the impossible – pure magic ! The topic has been in my to-do list for long and hopefully this article will be the trigger to learn it more thoroughly.
3. Math Vs Massive Data Overload
An interesting article about a new algorithm from IBM research to do data mining on large datasets. I also have to say that I really liked the article title. A Forbes article on the same topic is here . The basic idea is to avoid matrix factorizations which are costly and move towards stochastic estimation of the diagonal of inverse covariance matrix. Clever idea indeed !
4. The Game of Punctuality: Coincidence or Equilibrium? and Words as Networks in Spam Detection
Two interesting applications from Game Theory and Networks. I really like the idea of using word networks to combat spam. The idea is intriguing but I am not sure how this technique will handle posts like mine where each paragraph talks a different idea.

5. Fun Posts
Controversy is the new advertising from Krish Ashok.
Vinnai Thaandi Varuvaaya: Poetry – A review of VTV. I liked the movie even though I felt the second half was slightly long. The songs were a delight – especially Aaromale. The post has some good observations like Gautam Menon’s uncanny ability for perfect dialogues, his directorial approach which makes even movies with clichéd topics seem less clichéd. Like the author , I also observed that the movie was less crowded. It so obsessively focused on Simbhu and Trisha that other characters hardly had screen space or impact. It is in contrast to old Balachander movies where even minor characters had a well developed sketch. Not that I am complaining !
