Support vector machines always show a margin whose width changes. How can I find what my margin is ? Eg, if my weights are $[-1,1]$ what is my margin ? Also, do larger weights mean larger margin ?

    Have you seen the general discussion of SVMs at https://stats.stackexchange.com/questions/23391/how-does-a-support-vector-machine-svm-work? Perhaps that will help. Otherwise, search our site: https://stats.stackexchange.com/search?q=%5Bsvm%5D+margin. – whuber Jan 04 '18 at 14:05

Larger weights mean smaller margin. Given the weights you can compute the margin by 1/||w||.

  • thank you whuber and saibot. It was a matter of plugging in some values and vizualization. – Kong Jan 04 '18 at 14:37
