Unicode Upload with FileUpload
Hello,
I'm new to this list and hopefully it is OK to ask my question here ... ;-)
I'm using FileUpload to get data from a HTML form via POST method
(Apache Tomcat). It works fine, but the encoding of the file is always
damaged. For example, I have text files (XML) in UTF-8 encoding with
german special characters, but when uploading the file and printing its
content to the browser, all special characters are gone or replaced by
something strange.
This is the code I use (avoiding to write the file to the harddisk, I
used the most simple way from the manual):
-
// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Parse the request
List /* FileItem */ items = upload.parseRequest(request);
String xml = ;
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem fi = (FileItem) iter.next();
if (fi.isFormField()
fi.getFieldName().equals(nameCorpus)) {
nameCorpus = fi.getString();
} else {
byte[] data = fi.get();
int c;
for (i = 0; i data.length; i++) {
c = data[i];
xml = xml + (char) c;
//out.print( (char)c );
}
}// if else
} //while
out.print(xml);
-
It would be nice, when somebody has an idea how I can preserve the
Unicode content of the file ...?
Thank you very much in advance,
Tom

Basic Maths Help
Hi, I'm hoping that someone with a bit more maths knowledge than I have can help me with my current problem. I've got a data set that contains the daily closing price for a number of different stocks. What I want to do is find an equation that fits those points and then use it to predict the future price. In the past I've written an application that did a simple least squares linear regression (what is handled by the SimpleRegression class I believe) e.g. finding a line of best fit with the formula y = mx + c. What I need now is something that can give me a formula of y = ax^n + bx^n-1 mx + c where I can choose n, the number of terms. I think this can be handled by general least squares but the simple case I implemented in the past was already pushing my understanding of maths. Is this what the GLSMultipleLinearRegression class does? If so what do I need to read up on to understand it? Many thanks, Graham

Re: Release codec 1.4?
Hi, I'm mostly happy with the state of the CODEC in the repository. Base64 can be properly streamed when using the repository version, and I believe it's at least 33% faster than any of these: 1. http://iharder.sourceforge.net/base64/ (2 times faster) 2. sun.misc.BASE64Decoder (2 times faster) 3. openssl enc -base64 -d (about 33% faster?)

Re: Basic Maths Help
Thanks guys that's really useful and tells me I'm at least looking in the right area. I understand some of what you are talking about but the rest leaves me scratching my head in bewilderment. Do you happen to know of any good sites where I could learn about this? Many years ago I did advanced mathematics but that was focused on engineering rather than statistics so the ideas aren't completely alien to me. The solution I have at the moment gives really poor results so throwing polynomials at it would probably be an improvement but I understand what you are saying about over fitting to noise. 2009/7/13 Ted Dunning ted.dunn...@gmail.com And if you are really working on time series for stocks, you will likely have explosively bad results applying a simple polynomial fit. You should, at least, remove the long-term exponential trend. This is probably best done using something like lowess smoothing. If you are looking at long-term data, you should also rescale as a percentage of long term trend. Then for modeling the data, you have to be very careful to avoid over-fitting to noise. Simply throwing polynomials at the problem is the road to ruin. Without significant math skills it will be difficult to get really good results. You might try penalizing your fit by also minimizing the summed squares of your coefficients. This is equivalent to weight decay in neural networks. Commons math is probably a very nice way to implement such algorithms in production. For exploratory development, I would recommend R instead.

Re: Basic Maths Help
Ahh... excellent. Chris Bishop's book Pattern Recognition and Machine Learning is a *really* excellent resource for relatively modern machine learning. Also good is Andrew Gelman's book Data Analysis Using Regression and Multilevel Hierarchical Models, but you will have to read between the lines quite a bit with that to do time-series stuff. On the web, I would recommend you look into Gaussian Processes. This web site seems to be a good introduction with good further links: http://www.gaussianprocess.org/ David Mackay is always worth listening to: http://videolectures.net/gpip06_mackay_gpb/ That should keep you pretty engaged for a bit. When you come up for air, drop on over to the Apache Mahout mailing list where I can provide more information.

Re: [Sanselan] Writing XMP leads to semi-corrupted IPTC
