I am a Research Fellow on
the ISI-INSEAD fellowship
at the Machine Intelligence Unit
of Indian Statistical Institute,
Kolkata (known as Calcutta in the previous century).
I am working under the supervision of Prof. Sankar K. Pal .

Research Interests

Specific (I mostly work on these)
- Web Mining (Text and Link Analysis, Structure Mining, Surfer Models)
- Graph Theory (mostly where applicable to the Web)
- Fuzzy Logic (again, mostly where applicable to the Web)
- Data mining (Condensation, etc.)
- Text mining (Classification, Retrieval, Stemming)
- Information Theory (Entropy, in particular)
Broad (generally interested in them, or picked up from colleagues and have a working knowledge in them)
- Statistical Learning Theory
- Digital Signal Processing (Transforms like Fourier and Wavelets, Edge Detection)
- Pattern Recognition
- Soft Computing (Neural Networks, Fuzzy Logic, ...)
- Various other topics :)

Try these (Mostly for people within ISI... but anybody may make use of them)

ISIans (as well as just anybody else) can benefit from this Launcher which is designed to save time by loading only the non-trivial portions of some commonly accessed pages. Of course, one can easily modify it according to what he/she thinks is commonly accessed. This Launcher is distributed under the GPL. Feel free to copy, modify and redistribute it.

After debugging several C programs (both mine and those of my friends), I have listed some of the commonly encountered mistakes in C Check List.

Why surrender yourself to spam? Let ThunderBird take care of it. A set of instructions for installing and other information about Thunderbird 1.0 are available for ISIans. (The same ISI specific settings may be used while setting up Outlook Express or Netscape Mail)
