In other words, the customer could wait for a period of time to make sure that most of his important people have known the new GSM number. Mobile IMEI information containing a brand, model, type of mobile phone, and whether it is a dual or single SIM unit. In addition, we entered the features related to complaints submitted from the customers from all systems. This data has a large size and there is a lot of detailed information about it. Gerpott TJ, Rams W, Schindler A. We experimented three scenarios to deal with the unbalance problem which are oversampling, undersampling and without re-balancing. As the market in telecom is fiercely competitive, in that case, companies proactively have to determine the customers churn by analyzing their behavior and try to put effort and money in retaining the customers. Google Scholar. Similarly, panel (e) visualizes the distribution of Percentage of Signaling Error/Dropped calls. To reduce this complexity, customers who dont have mutual friends are excluded from these calculations. 2004;38(2):1638. The authors declare that they have no competing interests. Part of 11 and depending on Tables 2 and 3, we confirm that XGBOOST algorithm outperformed the rest of the tested algorithms with an AUC value of 93.3% so that it has been chosen to be the classification algorithm in this proposed predictive model. The total count of the sample where 5 million customers containing 300,000 churned customers and 4,700,000 active customers. if monthly payment for telecom service is between 100 and 400, age of the customers is . Big data system allowed SyriaTel Company to collect, store, process, aggregate the data easily regardless of its volume, variety, and complexity. System evaluation We evaluated the system by using new up to date dataset. [17] compared six different sampling techniques for oversampling regarding telecom churn prediction problem. By using this website, you agree to our We chose to perform cross-validation with 10-folds for validation and hyperparameter optimization. CoRR. As with any data type, care should be taken that the telecom data that you are buying is accurate and reliable. Yu W, Jutla DN, Sivakumar SC. A customer churn analysis is a typical classification problem within the domain of supervised learning. In the third . They gather the data related to dropped calls, bandwidth issues, poor download times, and the like to optimize their services with proper capacity planning, equipment monitoring, and preventive maintenance. Throughout the series, we have covered the theoretical concepts of JAX, and in this post, we will apply those concepts to train a machine learning model. The Churn column ( response variable) indicates whether the customer departed within the last month or not. Find AWS Partners to help you get started. Label the dataset for tracking, with a bounding box on each object (for example, pedestrian, car, and so on). GBM algorithm was trained and tested on the same data, we optimized the number of trees hyper-parameter with values up to 500 trees. We started with oversampling by duplicating the churn class to be balanced with the other class. In addition, it enabled extracting richer and more diverse features like SNAfeatures that provide additional information to enhance the churn predictive model. https://doi.org/10.1016/j.dss.2008.06.007. The percentage of the retained customers from Offered dataset was about 47% from all customers predicted to churn. Hortonworks data platform HDPbig data framework.

This result was very good for the company, increased the revenue and decreased the churn rate by about 1.5%. 2017;9(6):85468. The weighted Page Rank equation is defined as follows, While the weighted Sender Rank equation is defined as follow. Telecom Churn Prediction using Machine Learning, Python, and GridDB The goal of the researchers was to prove that big data greatly enhance the process of predicting the churn depending on the volume, variety, and velocity of the data. Decis Support Syst. The explanation here relies on the effect of friends on the churn decision, since the affiliation of most of customers friends to the other operator may be evidence of the good reputation or the strong existenceof the competing company in that region or community. A sample of customers with very low LCC were contacted to check this case. After exploring the data, we found that about 50% of all numeric variables contain one or two discrete values, and nearly 80% of all the categorical variables have Less than 10 categories, 15% of the numerical variables and 33% of the categorical variables have only one value. R and Python are invaluable methods for the study of telecommunications data. The volume of this dataset is about 70 Terabyte on HDFS Hadoop Distributed File System, and has different data formats which are structured, semi-structured, and unstructured. Churn Analysis of a Telecom Company - Analytics Vidhya The first idea was to aggregate values of columns per month (average, count, sum, max, min ) for each numerical column per customer, and the count of distinct values for categorical columns. Distribution of some main SNA features, panel (a) visualizes the feature distribution of Cosine Similarity Between GSM Operators, panel (b) visualizes the distribution of Local Cluster Coefficient feature, and panel (c) visualizes the distribution of Social Power Factor feature. Second, nodes with zero-incoming and many outgoing interactions. Customer retention, loyalty, and satisfaction in the German mobile cellular telecommunications market. Yet, relatively few robust methods have been reported in the field of structure-based drug discovery. In order to build the churn predictive system at SyriaTl, a big data platform must be installed. The second concern taken into consideration was the problem of the unbalanced dataset since three experiments were applied for all classification algorithms. These two kinds of nodes are called Sink nodes. This channel is defined as Memory Channel because it performed better thanthe other channels in FLUME. Elisabetta [11] also proposed an approximation method to compute the Betweenness with less complexity.
