Figure 7

The effect of the width parameter of the Gaussian kernel (σ) for a fixed value of the soft-margin constant.

For large values of σ (A), the decision boundary is nearly linear. As σ decreases, the flexibility of the decision boundary increases (B). Small values of σ lead to overfitting (C). The figure style follows that of Figure 3.
