在数字化时代,精准把握用户需求是网站实现精准营销与个性化服务的关键。针对该场景,提出了一种改进的奇异谱分析
K
均值(singular spectrum analysis
K
-means,SSA-
K
means)算法,有效地解决了传统SSA中窗口长度及特征分量须手动选取的低效问题。该算法先利用SSA提取用户访问数据的核心特征分量,再结合
K
-means进行聚类分析。实验结果表明,该算法显著地提升了聚类效果,戴维斯堡丁指数较直接聚类和小波变化去噪后聚类分别降低了0.407 1和0.067 2,簇划分更精准。基于优化后的聚类结果,进一步制定了差异化运营策略,针对不同用户群体提供定制化服务。这一方法为网站精准营销和用户留存提供了高效的解决方案,具有重要的实践应用价值。
In the digital age
accurately grasping user needs is the key to acheive accurate marketing and personalized services. Aiming at this scenario
an improved singular spectrum analysis
K
-means (SSA-
K
means) algorithm was proposed
which effectively solved the inefficient problem of manual selection of window length and feature components in the traditional SSA. Firstly
the SSA was used to extract the core feature components of user access data in this algorithm. Then
K
-means was combined for cluster analysis. The experimental results show that the clustering effect is significantly improved. The Davis-Burdin index is 0.407 1 and 0.067 2 lower than that of direct clustering and wavelet transform denoising clustering
respectively. Moreover
the cluster division is more accurate. Based on the optimized clustering results
a differentiated operation strategy was further developed to provide customized services for different user groups. This method provides an efficient solution for website precision marketing and user retention
and has important practical application value.
