problem of the time factor closing in around me...I had relatively
few problems. I struggled for a while about how to make all of
the data files work, and I think that I came up with the right
I've been writing
readMe files...nothing too extensive, just little files of what
everything is and how it all works. But it's a little bit of a
problem to decide what all goes in there! That's all though. Few
problems for the last week.
So I guess
I was a little embarrassed to admit this last week. I was very
frantically trying to solve the problem of clustering in different
numbers and types of dimensions at the same time. I was absolutely
positive that I was missing something completely obvious, and
I was just blind to whatever that something was. Got really frustrated,
yelled at the computer and the project a couple times. I talked
with Marie on Monday, and apparently that's a problem that hasn't
been solved yet! Good to know that I'm in good company.
week I was dealing with the apparent problem that my spring forces
were defective. I'll admit straight up, I have never taken physics
of any kind. High School, College, none. I had no idea what the
algorithms included in Prefuse were doing. While talking with
James, who is going to continue the project when we're done, he
gave me a few ideas to trace the error. Well, I did, and it turns
out it wasn't an error! The problem had to do with the masses
of the nodes themselves. It's mostly fixed, but it's still kind
And let me
reiterate the fact that I will die happy if I never see another
abstract action again.
enormous problems with, you know, stuff like balance, coordination
and general not injuring myself, I've had a few problems.
I know I had
problems, but I honestly cannot remember what they were.
Oh Weka. What
on earth are your class labels for? I must have them to cluster,
but all they do is tell you how many clusters to have, even if
I use the set cluster number method. It doesn't matter which Instance(s)
have what class label, as long as they're there. That was the
basis of my problems this week.
First I wasn't
getting a run through of the clustering method. Then I was only
getting one cluster. Then I figured it out. Oh, Weka.
All of my big
problems for this week seem to be unrelated to the project, and
mostly with residential life. But, I still had my moments in front
of the computer! Creating all of the vectors for the reading in
of the xml files was a chore...and so many loops. If I didn't
have any experience with Iterators before, I sure do now. I realize
that this is a great experience, but a small part of me wishes
that I could have had a little bit more experience before this!
But the best way to gain experience is to jump in, right? And
I guess now I know that I can figure my way through a problem,
and a little confidence is good.
So it appears
that this "problem" section for this week is mostly
musings, rather than distinct problems. I'm sure I'll have more
to report next week. You'll notice that I've started my archive,
and my Bryn Mawr site now mirrors this one, although it might
get updated a little less often.
