In this paper, we study the correlation modeling method between subjective assessments and objective metrics of handling and steering feel. The correlation model used is a multiple linear regression model. To resolve multicollinearity that can cause overfitting, we use ridge regression, which is a normalization method. Interaction terms between independent variables are also added to the multiple linear regression model so that correlations between objective metrics can be considered. As an application of the proposed method, correlation modeling between subjective assessments and objective metrics of handling and steering feel is performed. To evaluate the accuracy of the proposed model, we compare it with a multiple linear regression model based on the least square method and a ridge regression model without interaction term. Results show the ridge regression with interaction terms has the highest accuracy in terms of coefficient of determination and mean square error. |
