Support Vector Machines: $(4$ marks$)$ Consider the half$-$margin of maximum$-$margin

SVM defined by $,$ i$.$e$.=\frac{1}{||w||}.$ Show that $$ is given by:

$\frac{1}{{}^2}={\displaystyle \underset{i=1}{\overset{N}{}}}{}_i$

where ${}_i$ are the Lagrange multipliers given by the SVM dual $($as on Slide $30$ of the uploaded

SVM lecture slides$).($Hint: The answer involves just $3-4$ steps, if you are thinking of

something longer, re$-$think!$)$
