Description
-----------

Pre-built LibSVM packages for Python.

What is LibSVM?
---------------

Crated by Chih-Chung Chang and Chih-Jen Lin, LIBSVM is an integrated
software for support vector classification, (C-SVC, nu-SVC), regression
(epsilon-SVR, nu-SVR) and distribution estimation (one-class SVM). It
supports multi-class classification.

Purpose of this package
-----------------------

The idea behind this package is to use the same code as in
https://github.com/cjlin1/libsvm using the very convenient pip command

How to install
--------------

::

   pip install libsvm

Example
-------

1. Download https://github.com/cjlin1/libsvm/blob/master/heart_scale
   file.
2. Run the following commands

::

   >>> from libsvm.svmutil import *
   >>> y, x = svm_read_problem('path/to/heart_scale')
   >>> m = svm_train(y[:200], x[:200], '-c 4')
   *.*
   optimization finished, #iter = 257
   nu = 0.351161
   obj = -225.628984, rho = 0.636110
   nSV = 91, nBSV = 49
   Total nSV = 91
   >>> p_label, p_acc, p_val = svm_predict(y[200:], x[200:], m)
   Accuracy = 84.2857% (59/70) (classification)

Windows
-------

The package contains a pre-built Windows binary that is only compatible with 64 bits architecture; therefore,
32 bits architecture is not compatible.

Cygwin
______

In case that you want to install this package using Cygwin, you have to make sure that the
following packages are installed:

1. gcc-g++ >= 7.0.0
2. python38
3. python38-devel
4. python38-pip
