How to develop churn prediction model for telecom company?
In the competitive telecom sector, customers can easily switch from one provider to another, which lets the telecom providers worried about their customers and how to retain them but they can predict the customers who will move to another provider previously by analyzing their behavior.
They can retain them by providing offers and their preferred services according to their historical records so the aim of this study is to predict churn previously and detect the main factors that may let the user move to another provider in telecoms. Many studies are available for churn problem from different viewpoints with different datasets, algorithm and for different industries where churn analysis is one of the world wide used to analyze the customer behaviors and predict the customers who are about to leave the service agreement from a company.
Most of the literature focused more on data mining algorithms, but only a few of them focused on distinguishing the important input variables for churn prediction and on enhancing the data samples through efficient pre-processing to be used for data mining algorithms implementation  . Amin, A. Accuracy in the last tenth iteration was Andrews, R. They applied profound learning models and they used overlap cross approval methods to check the prediction exactness and the area under curve score is 0.

I would say that starting with the current CRM database is a solid base. Most likely, the number of customer care calls, the number of complaint e-mails etc.
Just counting will most likely not be sufficient though, you will need to analyze the content of the e-mail, audio from the conversations with customer care, web behavior and perhaps even social network analysis. You are right, the most important place to dig is in Customer Care system or better say CRM database. What I want is that what are the steps in an order way to design the prediction model and of course which model best suits for analyzing telecom data.
After researching a lot in whitepapers and articles in scholar. Here is my findings:. Step1: find as much attributes in telecom data as you can, and make a dataset of those data.
JanFebMar and extract those customers in this period of time JanFeb and March which leave the company Am i right? I want to know whether I am doing right or not? Am I right? After finding some assumptions or hypothesis or rules Am i right with this word?
Since you have a whole gamut of data available its just information which you need to extract from the same. You can take out the basic first and then derive more models later. In the above identified grey areas you need to define the mode for more drill down. Decision trees do the great job.
They are accurate enough and more important reveal why people churn. Just read the tree and you'll find out. Gini or ID3 or ChiSq? Try them all and compare. It's easy to train 20 trees in a 60 minutes and compare. The set of fields for the analysis seems reasonable.
However, in our experience with churn analysis in telecom industry and customer retention in general you have to capture not only the total or average values, but use a temporal abstraction approach, where you look at service usage and billing over the last N months before churn or current date if no churn. The steps are well described, e. With respect to the method selection, I would recommend trying Stochastic Gradient Boosting approach that usually gives robust and accurate results in such applications.
If you look for better interpretability, then classification trees and logistic regression might be of help. Although in the latter case you will have to check on initial assumptions e. Can some one send the Data set for working on Churn Predictive Model. I am a student from University of Illinois and this Data set would be of great help to work on our project.

Telecom-Churn-Prediction Telecom Churn Prediction using Machine Learning models Telecom companies need to predict which customers are at high risk of churn.
Analyse customer-level data of a leading telecom firm.Abstract:- Telecommunication has become an important for business, enabling companies to communicate effectively with its customers and allowing high standards of customer service. Due to the expansion of telecommunication market day by day and increased competition has resulted in huge loss of revenue as well loss of customers. The process of one customer leaving one telecom company and joining another telecom company is called as Churn.
In this paper we developed a prediction model for telecom customer churn. It represents large dataset in the form of graphs which helps to depict the outcome in the form of various data visualization. Churn is a very important area in which the telecom domain can make or lose their customers hence investing greater time to make predictions which in turn helps to make necessary business conclusions.
Churn reduction can be achieved effectively by analysing the past history of the potential customer systematically. The mobile communication has become the dominant medium for effective communication all over the world. In numerous countries, especially in developed, the telecom market is saturated to the extent that each new customer must be won over from the competitors.
Many public policies and standardised procedures of mobile communication allow the customer to easily switch over from one carrier to another. So, instead of winning a new customer it is far better to retain the old customers in the same network.
Hence, the telecom carriers have now shifted their focus from customer acquisition to customer retention. Churn in terms of telecom industries refers to the customer leaving the current company and moving towards the telecom company.
Managing of customer to remain in the particular telecom company is intact a difficult task. Customer churn is a notorious problem for most of the industries, affecting the revenues and standards of a company, subsequently resulting in difficulty for acquiring of new customers.
In the customer oriented telecommunication cycle, churn refers to the decision made by the customer about ending up the business relationship with a particular. Churn may also be referred as loss of clients or customers, who are intending to move their custom to a competing service provider. In order to manage customer churn more effectively, a company must build an accurate and more effective churn prediction technique.
To keep up in the competition and to acquire as many customers, most of the telecom service providers invest huge amount of revenue to expand their business in the beginning. Therefore, it has become important for the telecom operators to earn back the amount they invested along with at least the minimum profit within a very short period of time.
The Decision Trees, Nearest Neighbour, and Artificial Neural Networks are sum of the churn analysis techniques which perform two key tasks such as predicting whether a particular customer will churn and reasons for that particular customer to churn. These techniques address only percentage of churn, but they fail to identify the exact number of churners.
The problem confronting wireless telecommunications management is that it is very difficult to determine which subscribers leave the company and why. It is therefore more difficult to predict which customers are likely to leave the company, and devise cost effective incentives that will convince likely churners to easy.
In the past, churn has been identified as an issue of concern across most industry sectors.
In its most general sense it refers to the rate of loss of customers from a companys customer base. The churning out of the customers from the emerging business space like telecom and broadcast providers leads to the loss of revenue.
These companies aim at identifying the risk of churn in its early stages, as it is usually much cheaper to retain a customer than to try to win that customer back. If this risk can be accurately predicted, marketing departments can target customers efficiently with targeted incentives to.
Generally the churn refers to the defection of a customer.The customer experience wave has disrupted several industries and Telecom is one of them. If anything, it will lead to a complete burn out of resources. Customer retention is a more pragmatic solution to tackle customer churn.Cudamalloc vs cudamallocmanaged
Telecom companies cannot stray away from investing time, money and effort to keep customers delighted. Well, there are reasons for it. It gets even better. But you might ask why is there a sudden shift of focus on customer retention? Many telecom companies find themselves in a muddle because of the fact that the market has grown at a blistering pace.
For instance, leading cable MSOs Multiple Service Operators have entered the wireless field to further saturate an overgrown market and make competition even more stiff. The result? Customers leave and no amount of acquisition strategies is bringing them back!
Also, by looking at the market penetration values in saturated markets, it can be inferred that there is no space for new customers! If you take the United States alone, there are connections for citizens. Telecom companies, therefore, need to strategize wisely. Instead of looking outside for new revenue, they need to identify ways to retain existing customers — easier said than done though!Contain yourself near me
Source: Wikipedia. Telecom brands in Canada are already at it. Bell Canada and Telus reported increased wireless retention spending for both the full year and fourth quarter ofaccording to their annual report.
While telecom companies need to keep hold of their customers, doing it effectively and witnessing the results require an effective end-to-end strategy. Staying in sync with what your customers expect from you is the foundation to an effective customer retention strategy. And to stay in sync, you need to listen to customers across multiple touchpoints.
You need to be available for them, at their convenience so that you can record their feedback, specific queries and complaints at any particular time.
Which is why you need to attend to it at the very beginning and not let the dissatisfaction grow. This translates to acting on customer feedback on time, appeasing disgruntled customers and closing the loop effectively.
Recent advancements in technology might have made the playing field level but it has also paved way for telecom brands to be a lot more proactive. Invest in powerful analytics and insight tools to anticipate customer churn, predict customer behavior and devise strategies that boost retention as well as profitability. Map customer retention strategies costs with the expected ROI to effectively prioritize investments.
Telecom companies have to realign their priorities around customer retention. Given the wide range of services they offer — some of which are exclusive of one another — it is important that they deliver consistently delightful experiences and ensure that they build a journey for the customer that is seamless and cohesive.Machine Learning is the word of the mouth for everyone involved in the analytics world. Gone are those days of the traditional manual approach of taking key business decisions.
Machine Learning is the future and is here to stay. However, the term Machine Learning is not a new one. Machine Learning is the art of Predictive Analytics where a system is trained on a set of data to learn patterns from it and then tested to make predictions on a new set of data.
The more accurate the predictions are, the better the model performs. However, the metric for the accuracy of the model varies based on the domain one is working in. Predictive Analytics has several usages in the modern world. It has been implemented in almost all sectors to make better business decisions and to stay ahead in the market.
In this blog post, we would look into one of the key areas where Machine Learning has made its mark is the Customer Churn Prediction.
For any e-commerce business or businesses in which everything depends on the behavior of customers, retaining them is the number one priority for the organization.
Customer churn is the process in which the customers stop using the products or services of a business. Customer Churn or Customer Attrition is a better business strategy than acquiring the services of a new customer. Retaining the present customers is cost-effective, and a bit of effort could regain the trust that the customers might have lost on the services.
On the other hand, to get the service of the new customer, a business needs to spend a lot of time, and money on to the sales, and marketing department, more lucrative offers, and most importantly earning their trust. It would take more recourses to earn the trust of a new customer than to retain the existing one. There is a multitude of reasons why a customer could decide to stop using the services of a company. However, a couple of such reasons overwhelms others in the market.
Customer Service — This is one of the most important aspects on which business the growth of a business depends. A study showed that nearly ninety percent of the customer leave due to poor experience as modern era deems exceptional services, and experiences. Another study showed that almost fifty-nine percent of the people aged between twenty-five, and thirty share negative client experiences online.
Thus, poor customer experience not only results in the loss of a single customer but multiple customers as well which hinders the growth of the business in the process. Onboarding Process — Whenever the business is looking to attract a new customer to use their service, it is necessary that the on-boarding process which includes timely follow-ups, regular communications, updates about new products, and so on are being followed, and maintained consistently over a period of time.
Even a good marketing strategy would not save a business if it continues to lose customers at regular intervals due to other reasons and spend more money on acquiring new customers who are not guaranteed to be loyal. There is a lot of debate surrounding customer churn and acquiring new customers because the former is much more cost-effective and ensures business growth. Thus companies spend almost seven times more effort, and time to retain old customers than acquire a new one.
