Well, in the Psychology class I have been taking this semester (Introduction To Cognitive Learning), I was taught about Neural Networks and a certain Hebb’s Rule which allows a network to remember a previous configuration and use this configuration to interpret new information.

Boyer – Moore String Search (Good Suffix Shift)
December 7th, 2008 · 1 Comment · Computer Science, python
The next string search algorithm I am going to cover seems pretty cool since the match is made in a reverse fashion. We check if the last character in the keyword equals some character in the text and decrease from that point on.As a result, a mismatch is detected extremely fast and this is also [...]

Since I was quite bored this week (thanks to an October break I spent entirely in my room) and a homework assignment that quite seriously sucked balls, I decided to read something about strings and read about Suffix trees and decided to whip up an algorithm that would create a neat suffix tree by walking [...]

Essay Time!
September 26th, 2008 · 2 Comments · Computer Science, python
So, after a ghastly essay season in fall 2007 where I managed to get myself rejected from a bunch of colleges, I find myself in a similar situation again. This time, its Google/MS to whom I should be bragging without seeming like I’m bragging. Although these two have assumed that freshmen are losers, I plan [...]

I had the opportunity to work on an interesting problem:
Find a decent approximation for the Zeta function (large values), given by:
So, to make any sort of headway, I decided that I would have to look at the graph. Hence, I whipped up a script in Python:
