This research examines the precision of an adaptive neuro-fuzzy computing technique in estimating the anti-obesity property of a potent medicinal plant in a clinical dietary intervention. Even though a number of mathematical functions such as SPSS analysis have been proposed for modeling the anti-obesity properties estimation in terms of reduction in body mass index (BMI), body fat percentage, and body weight loss, there are still disadvantages of the models like very demanding in terms of calculation time. Since it is a very crucial problem, in this paper a process was constructed which simulates the anti-obesity activities of caraway (Carum carvi) a traditional medicine on obese women with adaptive neuro-fuzzy inference (ANFIS) method. The ANFIS results are compared with the support vector regression (SVR) results using root-mean-square error (RMSE) and coefficient of determination (R(2)). The experimental results show that an improvement in predictive accuracy and capability of generalization can be achieved by the ANFIS approach. The following statistical characteristics are obtained for BMI loss estimation: RMSE=0.032118 and R(2)=0.9964 in ANFIS testing and RMSE=0.47287 and R(2)=0.361 in SVR testing. For fat loss estimation: RMSE=0.23787 and R(2)=0.8599 in ANFIS testing and RMSE=0.32822 and R(2)=0.7814 in SVR testing. For weight loss estimation: RMSE=0.00000035601 and R(2)=1 in ANFIS testing and RMSE=0.17192 and R(2)=0.6607 in SVR testing. Because of that, it can be applied for practical purposes.
本研究考察了自适应神经模糊计算技术在临床饮食干预中估计一种有效药用植物抗肥胖特性的精度。尽管已经提出了许多数学函数,如SPSS分析,用于根据体重指数(BMI)降低、体脂百分比和体重减轻来模拟抗肥胖特性估计,但这些模型仍存在缺点,比如在计算时间方面要求很高。由于这是一个非常关键的问题,本文构建了一个过程,采用自适应神经模糊推理(ANFIS)方法模拟传统药物葛缕子(Carum carvi)对肥胖女性的抗肥胖活性。将ANFIS结果与支持向量回归(SVR)结果使用均方根误差(RMSE)和决定系数(R²)进行比较。实验结果表明,ANFIS方法可以提高预测精度和泛化能力。在BMI损失估计方面获得了以下统计特征:ANFIS测试中RMSE = 0.032118,R² = 0.9964;SVR测试中RMSE = 0.47287,R² = 0.361。对于脂肪损失估计:ANFIS测试中RMSE = 0.23787,R² = 0.8599;SVR测试中RMSE = 0.32822,R² = 0.7814。对于体重损失估计:ANFIS测试中RMSE = 微小值(原文此处可能有误,推测为极小值,暂按0.00000035601),R² = 1;SVR测试中RMSE = 0.17192,R² = 0.6607。因此,它可用于实际目的。
