Abstract：The traditional pretzel preparation method is based on experience and traditional techniques such as manual operation, formula ratio, baking time and temperature. Aiming at the characteristics of too many process parameters and low precision in the process of pretzel production under the traditional method, a random forest model based on logistic regression is proposed in this paper. The traditional random forest model has a long processing time and needs to be improved in accuracy. Therefore, this paper introduced logistic regression and threshold setting in the process of establishing subtrees to improve accuracy and speed, and mapped the path of the generated classification decision tree to the influence of various factors on the success rate of precrisp, thus providing a certain theoretical basis for manufacturers. The experimental results show that the stochastic forest prediction method based on logistic regression has higher prediction accuracy than the traditional stochastic forest.?????
