AB  - Widely used deep neural networks currently face limitations in achieving optimal performance for purchase intention prediction due to constraints on data volume and hyperparameter selection. To address this issue, based on the deep forest algorithm and further integrating evolutionary ensemble learning methods, this paper proposes a novel Deep Adaptive Evolutionary Ensemble (DAEE) model. This model introduces model diversity into the cascade layer, allowing it to adaptively adjust its structure to accommodate complex and evolving purchasing behavior patterns. Moreover, this paper optimizes the methods of obtaining feature vectors, enhancement vectors, and prediction results within the deep forest algorithm to enhance the model's predictive accuracy. Results demonstrate that the improved deep forest model not only possesses higher robustness but also shows an increase of 5.02% in AUC value compared to the baseline model. Furthermore, its training runtime speed is 6 times faster than that of deep models, and compared to other improved models, its accuracy has been enhanced by 0.9%.
