Abstract: This article presents an advanced real-time churn prediction system for telecommunications utilizing Long Short-Term Memory (LSTM) networks with attention mechanisms. The system processes multimodal data, including call patterns, messaging frequency, application usage metrics, and sentiment analysis from support interactions, to identify subtle indicators of customer disengagement. Unlike traditional approaches that rely on static snapshots, this sequential learning model captures the temporal evolution of customer relationships, enabling earlier and more accurate identification of at-risk subscribers, particularly "silent churners" who gradually disengage before formal cancellation. Additionally, the integration of real-time call analytics enhances the churn prediction system by incorporating sentiment analysis and topic modeling during customer interactions, offering deeper insights into the factors driving dissatisfaction. This combination allows for real-time intervention during customer calls, preventing churn by addressing issues promptly.

The dynamic retention framework incorporates adaptive threshold determination, personalized intervention selection, and multi-level adaptation mechanisms that continuously evolve based on intervention outcomes. Experimental evaluation demonstrates significant improvements in prediction accuracy, lead time, and business value compared to traditional methods, with customer support interactions and temporal features providing the highest predictive value. The architecture's real-time capabilities and multimodal integration address critical gaps in existing approaches, enabling telecommunications providers to implement timely, targeted retention strategies that substantially improve customer retention rates and overall service quality.
