One way could be to split your data into two parts, then build models using different similarity measures on one part and see how accurate it is at predicting against the other part - evaluation criteria could be accuracy, precision/recall/F1, mean square error, etc, depending on your use case. Then choose the model that gives the best results.Sujit Palhttps://www.blogger.com/profile/06835223352394332155noreply@blogger.comtag:blogger.com,1999:blog-7583720.post-57432656407363827142015-05-31T23:09:54.629-07:002015-05-31T23:09:54.629-07:00Hi
