| 中文摘要: |
| 位置属性对于线下消费的用户具有重要影响。为了有效提高个性化推荐精度,在对O2O电子商务特点进行用户特征分析的基础上,在推荐算法中引入当前时间参数和位置参数,提出了一种改进的基于梯度提升回归算法的O2O电子商务推荐模型。实验结果表明,改进的基于梯度提升回归算法的O2O电子商务推荐模型在实时性和准确性方面明显优于传统的推荐算法。 |
| 英文摘要: |
| Location attribute has important influence for offline consumption of users. In order to improve the accuracy of personalized recommendation, on the analysis of the O2O e-commerce with user characteristics, it introduces the current time and location parameters to the basis of the recommendation algorithm , and it is proposed based on an improved gradient boost O2O e-commerce recommendation model of regression algorithm. The experimental results show that the improved improve regression algorithm based on gradient O2O e-commerce recommendation model in real-time and accuracy is superior to the traditional recommendation algorithm. |
