| C4.5 features | Accuracy | Relative size | Advantages | Weak points |
| (i) No pruning (ii) No limit in number of nodes | 0.9945 | 100% | (i) Good accuracy | (i) Low interpretability because of the tree size (ii) Overfitting (iii) Difficult extrapolation out of the dataset |
| (i) Postpruning (confidence factor = 0.25) (ii) Online pruning (number of instances/node ≥ 2) | 0.8216 | 39% | (i) Encouraging accuracy (ii) Increased interpretability due to the reduction in the tree size | (i) Difficult extrapolation out of the dataset (ii) Dependence on measuring instruments (iii) Not good accuracy |
| (i) Fuzzy linguistic representation (ii) Postpruning (confidence factor = 0.25) (iii) Online pruning (number of instances/node ≥ 2) | 0.7503 | 32% | (i) Increased interpretability due to the linguistic approach (ii) Flexibility on measuring instruments (iii) Human observation of attributes | (i) Loss of precision |
