Rishabh,
Software which extract rules from data are my main "WorkingField" but
it's to bad that in present nothing rule generating algorithm (package) exist.
I do my best to get R programming skills until end2002 for my contribution in data-mining package development,because R is a great basic for this.
Some nice free-software ressources ( not R ) for this purpose are:
http://www.cs.waikato.ac.nz/ml/weka/ (look C4.5Part for rule generating)
http://fuzzy.cs.uni-magdeburg.de/~borgelt/software.html#dtree
(that's for you probably interesting, because it's very fast C4.5 implementation and you can use in lot of way prune to
reduce the complexity 750 variables!)
http://fuzzy.cs.uni-magdeburg.de/nefclass/nefclass.html
Or my present favorit from J.Mortensen (it's great) when you want analyse your data
with fuzzy strategies..........
http://inet.uni2.dk/~jemor/jfs.htm
P.S.
One question - i make electronic music with ComputerSoftware,too
and i'm statistican - what are the 750 variables and what is your classification criterium ? (if it is not a secret !)
regards,christian

Hi everyone,
Could somebody explain to me what is the package/function for
classification analysis. I am performing analysis of music files in the form
of MIDI files. I end up with about 750 dependent variables from the
analysis, I also have a number of independent/grouping variables that I set
manually. What I would like is to be able to predict which group a
particular MIDI files belongs to given the 750 dependent variables. In order
to this I have to perform classification analysis on a sample set of MIDI
files where I know what group they belong to. I want to extract the
'classification rule' that would enable me to predict the group of each MIDI
file (there would be a different classification rule for each grouping
variable). Can anybody explain what is the best way of doing this in R. What
is the best package/function that would enable me to perform classification
analysis.
Any help would be greatly appreciated.
Many Thanks For Your Help!

Thanks For your reply
I would really prefer to use R as I am using R for all the other exploratory
analysis that I am doing on the data

I have a large of variables (750) because I have a lot of version of each
kind of data. I analyse melody, rhythm, harmony, etc as a different stream
of data. For each one, I calculate a different versions, intervals, contour,
modulo, modulo of interval, etc. For each one of those I perform a different
kind of analysis, basic statistics, complexity measurements, etc. For each
kind of analysis there are five results each. E.g. for statistical, there is
mean, SD, MAD, COV, etc.
After performing all these different conversions/analysis I end up with
about 750 variables (6 * 5 * 5 * 5)
The classification groups are different depending on what set of MIDI files
I am analysing. In some sets the criteria is genre, subject (who played the
piece), composer, extract (which piece of music), etc.
