Data Analytics for Proactive Customer Retention

Customer churn, or loss of a client, is an issue in telecommunication, overseeing an account, and e-commerce. Acquiring new clients is a part more costly than holding existing ones. Thus, churn prediction becomes a commercial technique. Classic strategies such as logistic regression, decision trees, and random forests are a extraordinary beginning but fall short in addressing to course imbalance, moving behaviors, and requiring actionable outcomes. Recent studies have advanced churn prediction in three ways. First, ensemble approaches such as XGBoost, LightGBM, and CatBoost provide palatable execution, particularly when utilized in conjunction with oversampling strategies such as SMOTE and ADASYN. Second, hybrid deep learning models that combine CNNs, BiLSTMs, and attention mechanisms can superior learn adjacent, progressive, and global features with advanced recall and F1 scores. Third, online learning approaches allow models to diligently learn in real-time of progressing client behavior. This article describes these progressions and proposes a system for proactive upkeep utilizing data analytics. It is found that ensemble models have over 85-90% balanced accuracy, and hybrid profound models provide excellent execution. Versatility, feature importance, and interpretability are found to be of crucial importance for being of practical use.
