you kept the one with largest margin gamma star so you would hope you can get gamma star and in fact if you do a very good job of minimizing this regularized functional for small lambda then you do get gamma star so in other words if week l2 regularization leads to assuming optimization works week our two regularization will get you very high margin or the best possible March okay this this proof is a simple unlike a lot of you into this proofs I think this is genuinely simple okay the proof is essentially you write down
