document: Improvements and critique on Sugeno 's and Yasukawa 's qualitative modeling Investigates Sugeno 's and Yasukawa 's -LRB- 1993 -RRB- qualitative fuzzy modeling approach . We propose some easily implementable solutions for the unclear details of the original paper , such as trapezoid approximation of membership functions , rule creation from sample data points , and selection of important variables . We further suggest an improved parameter identification algorithm to be applied instead of the original one . These details are crucial concerning the method 's performance as it is shown in a comparative analysis and helps to improve the accuracy of the built-up model . Finally , we propose a possible further rule base reduction which can be applied successfully in certain cases . This improvement reduces the time requirement of the method by up to 16 % in our experiments
