torch-svm

SVM packages for Torch7.

torch-svm/sgd

Reimplementation of Leon Bottou's svmsgd and svmasgd (http://leon.bottou.org/projects/sgd). This implementation is 2-10 times slower depending on the sparsity of the input.

torch-svm/liblinear

This is wrapper around the well known LIBLINEAR library (http://www.csie.ntu.edu.tw/~cjlin/liblinear/).

Requirements

Only Torch7 (http://github.com/torch/torch7)

Building

git clone git://github.com/koraykv/torch-svm.git
luarocks make

Using

require 'svm'

d = svm.ascread('liblinear/liblinear/heart_scale')
model = liblinear.train(d)
labels,accuracy,dec = liblinear.predict(d,model)

Status

svmsgd and svmasgd implementations are supposed to be complete.
LIBLINEAR interface is supposed to be complete, I did not check all the possible flags. If you find that something is not working, let me know.
LIBSVM interface is mostly complete, but as of now passing in a precomputed kernel option is missing.
