游戏用户流失预警分析模型

数据预处理规则：采用IQR四分位法剔除登录时长、互动频次等指标中的极端异常值，对缺失的玩法参与数据采用“同熟练度+同注册时长”群体均值填充；流失预测算法：构建“基础属性-行为时序-外部因素”三维特征体系，改良BiLSTM模型引入注意力机制，强化近期行为对流失预测的权重，7日流失预测准确率达92%以上；流失聚类规则：基于“登录间隔增幅、互动量降幅、付费停滞天数”3类核心指标，通过K-Means模型将流失用户划分为5类，聚类纯度达89%；模型迭代规则：每日增量同步用户行为数据，每周进行模型重训，通过AUC值（需≥0.88）验证迭代效果，适配用户行为动态变化。Data Preprocessing Rules: The IQR quartile method is adopted to remove extreme outliers from indicators such as login duration and interaction frequency, and missing game participation data is filled with the group mean of users with the same proficiency level and registration duration. Churn Prediction Algorithm: A three-dimensional feature system covering "basic attributes - behavioral timelines - external factors" is constructed. The improved BiLSTM model introduces an attention mechanism to strengthen the weight of recent behaviors in churn prediction, achieving an accuracy of over 92% for 7-day churn prediction. Churn Clustering Rules: Based on three core indicators: login interval increase, interaction volume decrease, and number of days without payment, the K-Means model is used to cluster churned users into 5 categories, with a clustering purity of 89%. Model Iteration Rules: Daily incremental synchronization of user behavior data is conducted, and weekly model retraining is performed. The iteration effect is verified using the AUC score (required to be ≥0.88) to adapt to dynamic changes in user behavior.
