Figure 4: Probability distribution of MNIST (digit 3 vs. 8) features during the training of MP-Boost-.

Figure 4:

The color of each pixel (feature) indicates the relative probability with respect to which the feature is selected. As MP-Boost progresses, the probability of ineffective features (pixels in the background) decreases while that of efficient features (pixels shaping the digits) increases. The final distribution resembles a blurred version of digits 3 and 8.
