A Novel Framework for Mitigating Intra-Operator Customer Churn in Telecommunications
Global Communications Conference (GLOBECOM)(2018)CCF C
Abstract
Customer churn is one of the fundamental problems in telecommunications industry. Identifying potential churners in the early stage is an effective approach to preventing customer churn. Previous studies largely focused on churners from one operator to another. In this paper, we consider an interesting scenario where customer churn occurs within a specific operator (intra-operator), i.e., customers of China Mobile switch their telecommunication services from fourth generation (4G) to third generation/second generation (3G/2G). Since mechanism for intra-operator customer churn is quite different, previous studies fall short for this new problem. We propose a novel framework to address the emerging intra-operator customer churn problem by investigating the relations between \pmb4G service plans and switching behaviors of customers, unveiling the underpinned cause of the relations. Specifically, we first establish a classification criterion to estimate current service usage status of each customer. Then, we assign switching score to each customer which can be used to reflect switching likelihood of the customer. Finally, we establish the relations between 4G service plans and switching behaviors of customers by introducing two new concepts: changing trend and design evaluation score. We find that some features of 4G service plans indeed affect switching behaviors of customers significantly. Our framework can provide insight into the reasonable design of 4G service plans. Experimental results based on real data demonstrate the effectiveness of our framework.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
