Sensitivity to learning set reduction

We reduced the training set to 80% and then to 60% and we observed what will happen to the classification rate. We observed that the classification rate was decreasing. But even when the training set was reduced to 60% of its original size the classification rate decreasing only to 84%.


Table 5.1: Sensitivity to Training Set Redution (see figure 5.2 on page [*])
Number of elements in training set [%] Classes Rate [%]
100 92.39
80 89.13
60 84.78
