,Linear Separators
▶ Binary classification can be viewed as the task of separating
classes in feature space

,Linear Separators
▶ Which of the linear separators is optimal?
3/36
, Classification Margin
T
▶ Distance from example xi to the separator is r = w ∥wxi ∥+b
▶ Examples closest to the hyperplane are support vectors
▶ Margin ρ of the separator is the distance between support
vectors
