My project this year is about
Multidimensional Indexing, by looking into a indexing method called
"Pyramid Technique" which claim itself more efficient with higher
dimensionality thus towards breaking the CURSE OF DIMENSIONALITY. The
complete paper can be found
HERE!
My main objective has changed since mid-year, I was trying to generate datasets that would "break" the Pyramid Technique, but after take an insight look, the objective changed to compare the performance of the Pyramid Technique to the Sequential Scan, because generally all the indexing methods are bad when the dimension gets too high, and the Pyramid Technique is better than the other methods because it is not recursive, and it only partitions the space once and the indexing is handled by a B+ tree. So when the dimensionality gets high enough, it becomes several linear scans.
The implemented source codes are in my Articles.

Dumping my blog @ MSN, just to run away from my thoughts for a while. I always think too much, about love/relationships/moral/religion/... but can't help to feel worse and worse.
I still don't feel good about many things happening, but who cares, here is a place to study, life is a struggle, you have to struggle to live.
The reason I chose to study Computer Science in the first place is someone said to me it's not a good career for girls, like girls are all idiots or something, now I know he was right, mainly because computers are skin-killers, but I kinda enjoyed this subject and I don't know what else I am interested in, logical thinking is always my strength, but sometimes I still feel that I need a higher IQ in this Genius-Surrounded department... lol...
In Computer Science, women are rare, I am doing post-graduate now, there is only one female in my class,,, of course that's me. -_-;;;
It's a good and bad thing, you get more attention, but you also kinda left out... I guess I will just live the way I was, and try to focus on study, at least for the rest of 2007.
At last, a little introduction about myself
Name: Fay P
Place: University of Otago, Dunedin, New Zealand
Study: Computer Science, minor in Math
Interests: Music, reading, travel...
Programming: Java, C, html, Prolog... etc. Learning python by myself at the moment, and trying to understand ORACLE stuff.
