This week I
started working with Weka! Turns out it's a great package for
machine learning. I ran across it in my initial research, but
kind of just moved past it, but now we're using it. I'll have
to add it to my packages page, because it really is amazing. In
addition to Weka, we're also using WekaUT, which includes a number
of algorithms that we want to use.
So I created
my Instance(s) and my Instances and stuck them in the PCKMeans
function, and while it didn't work right away (see Problems),
it's working now, and as far as I can tell, working well. I have
to test it with a smaller data set in two or three dimensional
space, since I still have problems analyzing in n-dimensional
space.
I also started
to take into consideration more than one type of node in my data
structure setup. I'm not exactly sure how it'll work with clustering,
but am confident that we'll figure something out. But that's the
part of this that is the hard part, isn't it? Clustering more
than one types of data? We'll just have to make it work with Weka.
I spent a lot
of time stuck on the problems with Weka, and a good day clearing
out the data structures and variables that I didn't need that
I was using for COP-KMeans. It cleared up about half of my code,
if you can believe that! That data class was just eating away
vectors. This is much cleaner. I still have a lot of commented
code, but that's just in case I screw up again :)
In Other News:
Room situation is better now. During the walk-through, I pointed
out the fact (which I had already told them) that the bugs weren't
living in the apartment, they were living outside!
Putting traps wasn't going to do a thing for the bugs outside.
So they caulked the windows and I think that they sprayed outside
as well. They also replaced all of the smoke detectors, and they
haven't gone off since, I think. Even though they're taking care
of the bug problem, I moved into the room farthest from the light.
I just wanted to be out of a place that I associated with bugs!
I spent last
weekend in a Raid-induced stupor watching A.L.I.A.S. courtesy
of Leigh Ann Kopans, for which I thank her soooo much! I also
read Harry Potter on Monday, and all I can say is ***************
(content edited for those who have not read The Half-Blood
Prince. Then I read it again. I read books twice, once for
plot, once for content. I've resigned myself to the fact that
I just can't read a novel once and thoroughly appreciate it. Two
is the number. This weekend should be fairly standard though.
