Fig. 4.

Illustration of data generation with different values of $\mathit{\beta }$ and two features. The straight black line shows the coordinates of points where ${\rho }_i=1/2$. The percentage of observations labeled as 1 at the end of the generation procedure is displayed in the bottom-right corner. The top panels depict the class of each observation for varying values of ${\beta }_0$, while ${\beta }_1$ and ${\beta }_2$ are held constant. The bottom panels show the class of each observation with ${\beta }_0$ fixed at zero and, varying values of ${\beta }_1$ and ${\beta }_2$
