good boosting tutorial and package in R?
Hi all,
Could you please give me some pointers about what's the best boosting
package in R currently?
in terms of classification accuracy?
And any pointers about tutorials and study-materials to curb the
learning curve will be greatly appreciated!
Thank you!
p.s. Does anybody happen to know Boosting implemented in other
language such as Matlab?
Are they good in terms of accuracy?

Help! Please recommend good books/resources on visualizing data and understanding multivariate relations...
Hi all,
Could you please help me?
I am looking for books/pointers/resources/tutorials on visualizing
complex/big data and on understanding multivariate relations in complicated
data.
More specifically, we have categorical variables and are interested in how
to visualize the categorical data and visualize data conditioned upon
categorical values.
Could anybody please give me some pointers?

Statistical / data mining methods in R and not in SAS?
Hi, and sorry for asking such an unspecific question.
Does anybody know of statistical / data mining methods that are available in R
that are not in SAS ? With SAS I mean the SAS System Version 9.4 and SAS
Enterprise Miner. I don't expect a complete list, just two or three examples
or hints where and what to look for.
I found some older comparisons, and the R methods mentioned there

Hints for Data Mining
Dear All,
I am recycling a previous email of mine where I asked some questions
about clustering mixed numerical/categorical data. This time I am more
into data mining. I am given a set of known statistical indexes {s_i},
i=1,2...N for a N countries. These indexes in general are a both
numerical and categorical variables. For each country, I also have a
property x_i whose value is known, but

Help-Multi class classification for large datasets
Hai all,
We are working on Multi-class Classification. Currently up to 1.1 million
records Ranger package in R is able to handle. Training time on 128 GB RAM
is 12 days, which is not a practically feasible method to proceed further.
In future we will have dataset of dimension 10 million records, we are in
search for a package or framework which can handle 10 million records with
at least 12000

About classification methods.
Dear R users,
I'm new of the R, I really don't know much.
I want classification some data (two class, many features and huge size of data) by using R.
At this case, I want using Support Vector Machine, Bayes theory based classifier, Discriminant Analysis, Regression based at least.
Which package should I using, and can I compare each classifier result by predictions?
Thank you.

Classification Analysis
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

hands-on classification tutorial needed...
Hi all,
I am doing binary classification and want to improve the
classification results on imbalanced response data.
Currently the performance is poor. Are there ways I could improve the
performance?
I could either try different classification methodologies, or try
exploring the data more, and throwing away noisy data, and manipulate
the data more before sending into the classifiers.
I was

Scripts from The Elements of Statistical Learning book
Anyone know if it is possible to get the R scripts used in the "The Elements
of
Statistical Learning" book? It is a great book but sometimes some help would
be useful to replicate the results presented in the book and so, understood
things better.
Thanks

how to use the randomForest and rpart function?
Hi all,
I am trying to play around with the randomForest function for
classification. I know its performance is great.
I am currently using the default options.
It has many options.
How do I further tweak the options so that I can make its performance even
better?
What are the options that are mostly used?
Thanks a lot!

how to use the rpart function?
Hi all,
What parameter do I normally change in the rpart function? How do I set the
"cp" option?
Is there a way to read off error rate directly from the "rpart" function for
training data; I imagine for testing data I have to apply a "predict", but
for training data I guess the error count would be somewhere existing once
the "rpart" function is

R and Supervised learning
Luca:
1. We are not a consulting service. We *help* with R pogramming issues.
Users are typically expected to make an effort by providing R code and, if
appropriate, small data sets that illustrate their difficulties.
2. SEARCH! e.g. on "text processing R" or some such; or try Rseek.org with
such searches. R has extensive text processing capabilities, e.g. via
regex's.

Machine Learning and R
Hi all,
I am looking for a good book that covers Machine Learning as a whole
and provides examples in R while not over focusing on the math (such
as in 'Elements of Statistical Learning') but rather on descriptions
and examples. I am relatively new to R and ML and, while solving
problems with R, I want to learn the main concepts, techniques and
problem categories. Can anybody here
