[0039] In order to clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation modes and in conjunction with the accompanying drawings.
[0040] The cigarette ventilation rate prediction model based on the gradient lifting tree proposed by the present invention first uses the maximum information coefficient for feature selection, then uses the Bayesian optimization method for parameter optimization, and finally determines the cigarette ventilation rate according to the obtained optimal parameters. best predictive model.
[0041] The present invention considers that the maximum information coefficient is a method for analyzing the correlation between variables. Compared with the commonly used correlation coefficient, the maximum information coefficient is not only suitable for analyzing the linear relationship between variables, but also can be used for analyzing the nonlinear relationship be...
