| Abstract: | The application of decision tree algorithm for learning design strategies in parametric design was studied. Firstly, an example of a gear reducer layout design was discussed. Then the ID3 algorithm that could be used to learn design strategies was described, the design attributes and tests, which the program used to construct the decision trees was emphatically analyzed. Meanwhile, the automatic design procedures for creating new designs with the learned rules was described. Finally, the method with a reducer layout design sample and a number of experiments was tested. |
