I want to write this down, not to gloat, but to realize how many actual days
of my life I must have taken out to get these results.

Just done with the Bayesian Classifier
I am finally done with the Bayesian Classifier. I have been working on it on and
off for 3 weeks now. Glad to get it over with. So far, I have only been able to
plug a decent accuracy of 82% with too many false positives. Its disheartening,
but at this point of time, I feel it is the best that I can do. I thought I should
blog my feelings at this turn. In another 2 hours I have to go home. I’ll go home
and have a bath, been at the lab all night. I hope my efforts payoff.
First steps towards solid research
Alright friends, I am blogging my first steps towards some meaningful research
today. :))))))
I walked into the lab today and Vineet tells me that our classifier is doing a
100% accurate classification feeding off itself. Yes, I know that does not mean
much, but this opens a whole new set of possibilities. (For those not into data
mining, take my word for it, for the experts, just bear !!)
Some of the things we plan to look at
1. Can we boost the accuracy with Intelligent Keyword selection
2. Can we actually use incremental learning algorithms to induce decision trees
3. Do we need to bias the filters in filtering out junk email towards more
conservative filtering?
Now that we have the infrastructure in place we can answer all these questions.
Thanks Vineet for getting us this far!!!
Discriminative Classifiers
In an attempt to model the brain, Computer Scientists came up with the Neural
Network. On of the interesting things I learn about an NN is that it takes 15
days to ‘learn’ one task or problem (blunt but a laymans point of view).
So that would make it probably comparable to the learning rate of a child …
are we there yet?
Project work
Currently working really hard on two fronts,
1. Writing out a paper for the Knowledge Discovery in Databases conference
2. My text classification project
and of course there is my course work. Of course this is not in order of priority.
Or atleast I hope !!!
Before you join Computer Science
All you folks planning an MS in Computer Science this year, this link is for you.
Its a presentation given to Undergraduates by one of the smarter PhD’s around
here ;). I especially liked the bit about the knowledge spectrum. The overview
of technologies also includes game programming. What is really interesting
is the attrition rate of students hopping off from Computer Science to
Information Technology.
Algorithms in Computer Science
The algorithms exam really had me thinking for some time. Although I lost most
marks to carelessness, I really did not have an idea to solve this problem "
Give an O (V+E) algorithm to find shortest paths from a single source for
a directed weighted graph with edge weights only 1 and 2." As it ironically
turns out, this brainteaser has a sarcastically easy solution. If you pester me
enough I shall reveal it to you 🙂
This weekend is a busy one, with work required on the project and on a proposal
for research studies.
Stress Week
The stress week begins, my friend put me off to sleep yesterday, very grateful
for that. If I had not slept I would probably screw up later on this week. I hear
you can develop Dementia from lack of sleep. hehe !!
Distributed Artificial Intelligence
I have begun work on my Distributed Artificial Intelligence project with several
email exchanges with my professor Michael Van Wie.
Mike is an excellent person and I know that it is going to be a good experience
to work for him. Soon enough the project website will be up for this one too.
This project also looks like it is going to be a lot more long-term like the Data
Mining project to mine weblogs.
I am also looking at the Prisoner’s Dilemma. Or should I call it ‘Santosh’s
perpetual dilemma.
The week ahead is going to be tough unfortunately, with mid-terms and project
and homework deadlines interleaved. But thats the way it is here at RIT. Plans
don’t work, execution does.
CS New Building
Computer Science Department has moved to the New Building. !!!
Large and spacious, the CS department now has an entire floor dedicated
to themselves. My perspective, this does not really compare to Bhageraath
but atleast now I know my dollars are’nt going down the drain. The building
maybe modern, but for now the facilities and Computers will remain the same.
This only reinforces my decision to stay with RIT.
Pictures will be put up here very soon !
