As illustrated by Table 24 and 25, the coverage of the default rule generally decreases and the accuracy of the default rule generally increases in BruteDL+ compared to the storing-all-rules BruteDL presented in the previous chapter. The only exception is the hepatitis domain. Note that the storing-all-homogeneous-rules strategy works especially well on that domain.
