Machine Learning & Support Vector Machines (SVM) Lecture 9 CSCSI 494

March 7th, 2012 admin No comments

Last lecture we discussed the major topics in machine learning and an important classification algorithm entitled Support Vector Machines (SVM). Modern search engines use a combination of these fundamental techniques to find the relevance of documents w.r.t a given search query.
Papers to read: Standard SVM [Cortes and Vapnik, 1995]

We also discussed a two dimensional problem and showed how to expand a machine learning problem to infinite dimensions.
