Large Margin Filtering

Description

This code is an implementation of the large margin filtering method for both 1D sequence labeling and 2D pixel classification in images. It is the code that has been used in the paper Large Margin Filtering.

In addition the package contains an updated version of the Toolbox SVM-KM (with classifiers defined as a structure and not a bunch of matrices), and general function for validation/cross validation.

This package contains:

  • SVM-KM : SVM and kernel methods toolbox (see here)
  • Wrappers function svmclass2 that permits to learn different SVM
  • Solvers (libsvm, monqp, svqp2, ...)
  • Other methods: GMM (using netlabs)

Download

Current version : 0.9

Download : FilterSVM.zip

Installation

Quick version:

  • Add all the paths and subpath to matlab.
  • Execute make.m to compile the mex file (to use libsvm/svqp2)
  • Entry file : Dataset_Toy/Test_FilterSVM.m
