Support vector regression (SVR) is able to consider the nonlinear relationship between explanatory variablesXand a target variableyto build a regression model with high predictive accuracy. Additionally,yvalues predicted with SVR models for new samples can exceed the actualyvalues in training data. However, because the Gaussian kernel, which is a kernel function generally used in SVR, is based on the Euclidean distance between samples, it is unable to consider the importance ofXwhen building the regression model. Therefore, in this study, the focus was on the importance ofXthat can be calculated by random forests (RF), and a novel SVR method, called variable importance‐considering support vector regression (VI‐SVR), was proposed based on this importance. BecauseXis weighted based on importance, the greater the importance ofX, the greater its contribution to the predicted value. Analysis using the spectral, quantitative structure–property relationship (QSPR), and quantitative structure–activity relationship (QSAR) datasets confirmed that the predictive accuracy of VI‐SVR was better than that of SVR. VI‐SVR Python code is available at https://github.com/hkaneko1985/dcekit.
