Figure 2

Illustration of the convergence process: (a) the first linear classifier trained ( 𝑖 = 5 0 , 𝑇 = 1 ), (b) several additional weak classifiers added ( 𝑖 = 2 5 0 , 𝑇 = 5 ), (c) the data separation corresponding to the set of classifiers in (b). Background color shows class generated by classifier, form and color of data points show actual label 𝑦 , (d) data separation achieved after convergence ( 𝑖 = 5 0 0 0 , 𝑇 = 1 0 0 ).
