Customer churn is a major problem and one of the most important concerns for large companies. Due to the direct effect on the revenues of the companies, especially in the telecom field, companies are seeking to develop means to predict potential customer to churn.
Therefore, finding factors that increase customer churn is important to take necessary actions to reduce this churn. The main contribution of our work is to develop a churn prediction model which assists telecom operators to predict customers who are most likely subject to churn.
Another main contribution is to use customer social network in the prediction model by extracting Social Network Analysis SNA features. The use of SNA enhanced the performance of the model from 84 to The model was prepared and tested through Spark environment by working on a large dataset created by transforming big raw data provided by SyriaTel telecom company.
This algorithm was used for classification in this churn predictive model. The telecommunications sector has become one of the main industries in developed countries. The technical progress and the increasing number of operators raised the level of competition [ 1 ]. Companies are working hard to survive in this competitive market depending on multiple strategies.
Three main strategies have been proposed to generate more revenues [ 2 ]: 1 acquire new customers, 2 upsell the existing customers, and 3 increase the retention period of customers. However, comparing these strategies taking the value of return on investment RoI of each into account has shown that the third strategy is the most profitable strategy [ 2 ], proves that retaining an existing customer costs much lower than acquiring a new one [ 3 ], in addition to being considered much easier than the upselling strategy [ 4 ].
On the other hand, predicting the customers who are likely to leave the company will represent potentially large additional revenue source if it is done in the early phase [ 3 ]. Many research confirmed that machine learning technology is highly efficient to predict this situation.
This technique is applied through learning from previous data [ 67 ]. The data also comes very fast and needs a suitable big data platform to handle it.
The dataset is aggregated to extract features for each customer. SNA features made good enhancement in AUC results and that is due to the contribution of these features in giving more different information about the customers. We focused on evaluating and analyzing the performance of a set of tree-based machine learning methods and algorithms for predicting churn in telecommunications companies.
We have experimented a number of algorithms such as Decision Tree, Random Forest, Gradient Boost Machine Tree and XGBoost tree to build the predictive model of customer Churn after developing our data preparation, feature engineering, and feature selection methods. SyriaTel company was interested in this field of study because acquiring a new customer costs six times higher than the cost of retaining the customer likely to churn. We experimented three scenarios to deal with the unbalance problem which are oversampling, undersampling and without re-balancing.
Data Mining techniques were applied on top of the Data Warehouse system, but the model failed to give high results using this data. The Data Warehouse was not able to acquire, store, and process that huge amount of data at the same time.
The computational complexity of SNA measures is very high due to the nature of the iterative calculations done on a big scale graph, as mentioned in Eqs.
Big data system allowed SyriaTel Company to collect, store, process, aggregate the data easily regardless of its volume, variety, and complexity. We believe that big data facilitated the process of feature engineering which is one of the most difficult and complex processes in building predictive models.
By using the big data platform, we give the power to SyriaTel company to go farther with big data sources. The model also was evaluated using a new dataset and the impact of this system to the decision to churn was tested.
The model gave good results and was deployed to production.Currently they have been Focusing on retaining their customers on a reactive basis when the subscriber calls in to close the account by targeted proactive retention programs, which include usage enhancing marketing programs to increase minutes of usage,migration of plans, and a bundling strategy.
Retention drivers vary by market maturity, delivering excellent quality keeps customer happy and loyal. Among the problems they report are slow download speeds. Another key finding of Acquisition and Retention Survey Report is that recommendations from family and friends have gained in importance in the decision to switch operators. Subscribers who have switched operators in recent months reported two key information success in their decision. Skip to content. The Problem is to discuss a survey report where the Mobicom management team was concerned that the market environment of rising churn rates will hit them even harder as churn rate at Mobicom is relatively high.
The Acquistion and Retention Survey Report Retention drivers vary by market maturity, delivering excellent quality keeps customer happy and loyal. The Challenge To be able to effectively drive these retention strategies, a few key questions requires urgent attention What the top five factors driving likelihood of churn at Mobicom.
Recommend rate plan migration as a proactive strategy and how to prioritization customer for a proactive retention campaigns in the future.Final Presentation Customer Churn in Telecom Industry
The Decision We use R-programming the most widely used language and tool for machine learning and statistical computing to derive a model that can answer the solution.
The Data Source Consists of 80, rows of data with 27 indicators. Our Deployment Strategy Data Aggregation: We use various sources of data to complied into one meaningful data set. Data Cleaning: We go through regorious sanity check to impute the missing values, outliers to compile it one meaningful dataset. Transformation: using complex machine learning techniques we create a model that results in answering all the solutions The Machine Learning Model A Comprehensive Machine Learning Model The Solution using the Machine Learning Model, we are able to figure out the top factors driving likelihood of churn.
About the Program
And recommended a rate plan migration as a proactive strategy. Further recommend the following points to prioritize from the churn model for a proactive retention campaigns in the future : Not to have Drop voice calls which leads to churn and also need to improve data connectivity problems which also plays an important part in retention of customers.
