The J48 algorithm grows an initial tree using the divide
and conquers technique. Fig 1 shows the visualization of the
tree from modeling the dataset using the J48 algorithm. The
tree is pruned to evade over fitting. The tree-construction in
J48 differs with the tree-construction in several respects
from REPTREE in Fig 2. These two trees show a graphical
representation of the relations that exist in the dataset.
Knowledge is represented mainly from the classification and
prediction model in a tree structure.
