Introduction
INTRODUCTION
In today’s dynamic and fiercely competitive telecom industry, retaining customers is paramount for sustaining business growth and ensuring profitability. With a plethora of options available to consumers, telecom companies face the significant challenge of minimizing customer churn, the phenomenon where existing customers switch to competitors’ services. Customer churn not only leads to revenue loss but also incurs substantial acquisition costs as companies must invest in attracting new customers to offset the losses. To address this challenge, predictive analytics, and machine learning algorithms have emerged as powerful tools that enable telecom companies to foresee customer churn and take proactive measures to retain valuable subscribers. By leveraging historical customer data and employing advanced analytical techniques, telecom companies can gain valuable insights into customer behavior, preferences, and patterns, allowing them to predict churn and implement targeted retention strategies. . The study also investigates the crucial factors contributing to customer churn, ranging from customer demographics to usage patterns, customer service interactions, and pricing plans. By discerning the key drivers of churn, telecom companies can tailor their retention efforts to address these specific issues. Moreover, the interpretability of machine learning models will be explored to provide actionable insights into why customers churn, empowering telecom companies to make informed business decisions. The study’s findings hold immense practical significance for the telecom industry, offering actionable strategies to reduce churn rates, enhance customer satisfaction, and optimize business operations. By harnessing the power of machine learning, telecom companies can proactively engage with their customers, foster loyalty, and ensure long-term sustainability in the ever-evolving telecommunications landscape. Advances in cancer research have led to significant improvements in diagnosis, treatment, and survival rates for many types of cancer.
II. METHODOLOGY
A. Data Collection
This is an important step in achieving our model's goal. Unnecessary data is discovered in datasets while training the model, resulting in a reduction in model accuracy. As a result, Data collection on a dataset is used to solve these issues. Customer data comprises the data-based contact information and services of customers. Moreover, various packages, services and offers taken by customer. Also, it contains CRM system including information generated from all customer GSMs such as gender, birth date, the location and type of subscription etc.
B. Information Gathering
Mobile IMEI information comprises the model, type, model of the mobile phone and whether mono or dual SIM device. Data may have large size which may require information in detailed. It requires a lot of time for understanding. It also needs to know the original sources along with format for storage. Moreover, related to these records, data must be linked to each other logically using relational databases that actually represent customers detailed information.Call Details Records (CDRs) includes modifiable data related to MMS, calls, SMS etc. Also, transaction made by customers using internet which is ultimately generated in the form of text files.
C. Plan Itenary
One of the most important features of customer churn analysis is the itenary planning feature. n the telecom industry, customers are able to choose from multiple service providers and actively switch from one operator to another. In this highly competitive market, the telecommunications industry experiences an average of 15-25% annual churn rate. Given the fact that it costs 5-10 times more to acquire a new customer than to retain an existing one, customer retention has now become even more. In this project, we will analyse customer-level data of a leading telecom firm, build predictive models to identify customers at high risk of churn and identify the main indicators of churn.
III. ALGORITHM
A. SVM
SVMs can model non-linear decision boundaries effectively using techniques like the kernel trick, which transforms data into a higher dimensional space where non-linear relationships become linear. SVMs are less prone to overfitting, especially when compared to some other machine learning algorithms.
Step 1: Load the important libraries.
Step 2: Import dataset and extract the X variables and Y separately.
Step 3: Divide the dataset into train and test.
Step 4: Initializing the SVM classifier model.
Step 5: Fitting the SVM classifier model.
Step 6: Coming up with predictions.
Step 7:Evaluating model’s performance.
C. Decision Tree
Decision Trees provide a transparent and interpretable model. Decision Trees can be visually represented, allowing healthcare practitioners to visualize the decision-making process Decision Trees are less sensitive to data preprocessing steps like scaling and normalization compared to some other machine learning algorithms.
Step 1: Start with your idea. Begin your diagram with one main idea or decision.
Step 2: Add chance and decision nodes.
Step 3: Expand until you reach endpoints.
Step 4: Calculate tree values.
Step 5: Evaluate outcomes.
