LibSVM is an efficient solver for SVM classification and regression problems.
The svm extension wraps this in a PHP interface for easy use in PHP scripts.

The basic process is to define parameters, supply training data to generate a
model on, then make predictions based on the model. There are a default set

In a document classification problem, say a spam checker, each line would

the total scaled to unit length). Features that were 0 (e.g. the word did

Libsvm itself is required, and is available through some package
management - libsvm-devel for RPM based system or libsvm-dev for
Debian based ones. Alternatively it is available direct from the website.
If installing from the <link xlink:href="&url.svm;">official website</link>
then some steps will need to be taken as the package does not install
automatically. For example, assuming the latest version is 3.1:
