Who would use vector machines? e tools we mention below have a
formidable list of arguments. e user would do well to explore known
practice sets before using the tool.
How do we implement vector machines?
• SVMlight (http://svmlight.joachims.org/), and its brethren SVMperf,
SVMstruct, and SVMrank, are implemented in C. Note that this
program is free only for scientic use; commercial providers must
contact Joachims at Cornell University.
• SVMstruct is a Support Vector Machine (SVM) algorithm for
predicting multivariate or structured outputs.
• SVMperf is an implementation of the SVM formulation for opti-
mizing multiva ...
