How to do customer churn prediction using machine learning

Customer churn prediction using machine learning is there to help you understand the customers with risk and know why they want to leave.

 

Customer churn is a term that describes the number of customers who do not come back after the trial period. That can happen at different levels — micro-churn refers to the customer that only did business once. In contrast, macro-churn describes customers that have left after months or years of business with the company. Customer churn prediction using machine learning allows one to understand which customers will most likely churn. Understanding their behavior and why they want to leave will help you implement strategies to reduce the amount of business that goes with them.

 

How to get started with customer churn prediction

Customer Churn Prediction is a fascinating topic in the field of business intelligence. Businesses with products or services use predictive analytics to predict customer churn and keep them happy.

 

It does not matter the size of your business and the model you are using; if there are products and services, you sell. The focus is on customer retention using machine learning. It is vital to keep the customers with you for a reasonable duration of time, and it can be very challenging at the same time.

 

Predictive Analytics helps businesses to make better decisions on how they will retain their existing customers and avoid losing them to competitors. Predictive Analytics uses data from past events to predict future results, like predicting customer churn rates based on historical data about your customers’ behavior. It has been proven over time that predictive analytics can help businesses significantly improve operational efficiency and increase profits by making better decisions based on data instead of intuition alone.

 

How to work on predicting customer churn using machine learning

 

There are several steps to follow for predicting customer churn using machine learning. They are as follows:

 

Knowing the problem and defining the goal

At the start, it is essential to know the problem thoroughly and determine the goal for the analysis. That will help in determining the type of machine learning to apply. It can be either classification or regression.

 

Collection of data

To give the required feedback as asked by the company.

 

The first thing that you need to do is determine what kind of data you have. The most common types of data are transactional, behavioral, and attitudinal. For example, if you are working on customer churn prediction for a telecom company, the transactional data would include the number of calls made and SMSs sent; behavioral data would consist of location history and social interactions, and attitudinal data would include reviews on social media channels.

 

Get the reviews done on social media.

 

It would help if you also got reviews on social media channels like Facebook, Twitter or Instagram. You can use these reviews to see how many people are dissatisfied or happy with their services. If they are unhappy with it, they might leave soon, so you should try to understand why you are unhappy with it and try fixing those problems before they go to your service provider.

 

Doing the services related to the analytics.

 

After determining which type of machine learning will be used for churn prediction analysis, we need to identify what kind of model will be used for this purpose. Here we will have two categories: supervised models (binary classification) and unsupervised models (clustering). In this section

 

Preparation and processing of data

The first step of data preparation is to get the correct data. The data can get collected from different sources (like public websites, social media, etc.). After that, we must ensure that the information units are consistent and in the correct format. Usually, we have to clean up the data before we apply any machine learning algorithms to it. This stage is called preprocessing and is essential for the next step, feature engineering.

 

In this stage, we focus on converting our raw data into features or columns that our model can use as inputs. We also want to ensure that every part has a unique label (an identifier). In most cases, we need to add some labeler (this could be a human or an automatic system). For our model to learn from this data, we need to transform it into something that makes sense for computers and humans. This process is called feature engineering, and it’s a crucial part of any machine learning project since it defines how your model will behave in future use cases – if you don’t take care of this stage properly, then it will be difficult or impossible to use your model later on.

 

Testing and modeling

In this stage, the model for predictive machine learning will get created. Also, the stage will include performance monitoring, validation of the model and using parameters tuning steps. That will help get the correct customer churn prediction using machine learning with the help of data points.

 

In this stage, we will create a model that can predict whether or not a customer will churn. We will use different algorithms like kNN, SVM and linear regressions to build our models. We will also evaluate them based on their performance and training and the test set’s accuracy.

 

After creating a model, we need to evaluate it using different methods like accuracy, sensitivity, specificity etc., to see how accurate it is in predicting customer churns correctly.

 

Application and monitoring

The application is the final stage of customer churn prediction for machine learning. The new system can be integrated into the software or used for the new application.

 

The machine learning model will be trained again and then used to predict customer churn rates. The predicted value is then compared to the actual value, and the difference between them is calculated as a loss function. This loss function should get minimized by using various algorithms such as stochastic gradient descent or reinforcement learning algorithms.

 

Conclusion

Customer churn prediction using machine learning is there to help you understand the customers with risk and know why they want to leave. Knowing their reasons and why they left will help you find new ways of retaining them.
