A support vector machine picks the separating line with the widest margin to the nearest points of each class — the support vectors. A fatter margin generalizes better to new data. Try to hand-tune the line to maximize the dashed gap. Educational tool.

Governing equation

w, b min \frac{1}{2} ∥ w ∥^{2} s.t. y_{i} (w \cdot x_{i} + b) \geq 1, margin = \frac{2}{∥ w ∥} = 0.000

Reading this result: This orientation misclassifies at least one point, so the margin is meaningless until the two classes are cleanly separated first.
