Reading: mostly, math, bio, stats, probabilities, etc.
2004 -- 2005 (Physics, speech recogniftion, biological sequences, etc.)
For a while I worked on a range of research topics until the DNA microarray analysis project came along.

Learning Framework for Detecting Remote Non-Coding RNA Homologies.
In Proc. 13th Int. Conf. Intelligent Systems for Computational Biol., Detroit. Poster
(I still
have some semi-finished and unpublished stuff from this work.
Because at that time we didn't have a high performance computing
center at MSU some of these ideas were tedious to verify since the key
statistical model used with noncoding RNA -- stochastic context free
grammar first introduced by Chomsky -- has O(N^3) complexity. On a
positive note though, this project gave me a decent exposure to
biological sequence modeling.)
JR Deller, KH Desai, YP Yang
(2005) A
decision-theoretic framework for the evaluation of language models used
in speech recognizers. In Journal of Natural
Language Engineering.
(The idea in this paper, concieved by my mentor Prof. Deller, was quite theoretical and gave me a great exposure to Detection and Estimation.)
K Hoang, KH Desai, SD Mahanti
(2005) Charge
ordering and self-assembled nanostructures in a fcc Coulomb lattice gas. In Physical Review B.
(
I did this work while I was working as an RA in the condensed matter group of Prof. Mahanti.
I did the statistical and computational work underlying this
publication and later on Hoang joined me with his statistical physics
expertise to help me get it published. Strucutres discovered in this
work became instrumental for a multi-million dollar MURI project on
thermoelectric materials and devices. I believe the MURI
project is still in progress at MSU.)
2001 -- 2004 (Signal processing for communications systems)
I started my MS in EE in the fall of 2001. For the first couple of
years I was working on Communication circuitry and related signal
processing. These are some relics from that old (and really unexciting)
world. Surprisingly though, some matrix inversion related stuff that I
did in my MS thesis came really handy while formulating Tellipsoid.
