Churn analysis is an important tool for companies as it can reduce the costs that are related to customer churn. Churn prediction is the process of identifying users before they churn, this is done by implementing methods on collected data in order to ﬁnd patterns that can be helpful when predicting new churners in the future.The objective of this report is to identify churners with the use of surveys collected from diﬀerent golfclubs, their members and guests. This was accomplished by testing several diﬀerent supervised machine learning algorithms in order to ﬁnd the diﬀerent classes and to s

Population churn--the population turnover experienced by a community--can have differential effects on a community. Mass society theory suggests that because the churn rate experienced by communities can contribute to their uprooting, fragmentation, and isolation, churn is a potent threat to the stability of our modern day communities. Social capital theory, to the contrary, suggests otherwise. Social capital theory suggests that churn can have positive effects on communities by bringing new migrants with valuable human capital skills and experiences to communities. These migrants bring to the

Customer churn is problematic for any business trying to expand their customer base. The acquisition of new customers to replace churned ones are associated with additional costs, whereas taking measures to retain existing customers may prove more cost efficient. As such, it is of interest to estimate the time until the occurrence of a potential churn for every customer in order to take preventive measures. The application of deep learning and machine learning to this type of problem using time series data is relatively new and there is a lot of recent research on this topic. This thesis is ba

Predicting when a customer is about to turn to a competitor can be difficult, yet extremely valuable from a business perspective. The moment a customer stops being considered a customer is known as churn, a widely researched topic in several industries when dealing with subscription-services. However, in industries with non-subscription services and products, defining churn can be a daunting task and the existing literature does not fully cover this field. Therefore, this thesis can be seen as a contribution to current research, specially when not having a set definition for churn. A definitio

Subscription-based services are becoming more popular in today’s society. Therefore, any company that engages in the subscription-based business needs to understand the user behavior and minimize the number of users canceling their subscription, i.e. minimize churn. According to marketing metrics, the probability of selling to an existing user is markedly higher than selling to a brand new user. Nonetheless, it is of great importance that more focus is directed towards preventing users from leaving the service, in other words preventing user churn.

Churn prediction is used to identify customers that are becoming less loyal and is an important tool for companies that want to stay competitive in a rapidly growing market. In retail, a dynamic definition of churn is needed to identify churners correctly. Customer Lifetime Value (CLV) is the monetary value of a customer relationship. No change in CLV for a given customer indicates a decrease in loyalty. This thesis proposes a novel approach to churn prediction. The proposed model uses a Recurrent Neural Network to identify churners based on Customer Lifetime Value time series regression. The

As markets have become increasingly saturated, companies have acknowledged that their business strategies need to focus on identifying those customers who are most likely to churn. To address this, a method is required that can identify these customers, so that proactive retention campaigns can be deployed in a bid to retain them. To further complicate this, retention campaigns can be costly. To reduce cost and maximise effectiveness, churn prediction has to be as accurate as possible to ensure that only the customers who are planning to switch their service providers are being targeted for re

The main topics are consistency and distributed hash tables. One unsolved problem with distributed hash tables is consistent lookup. Various DHTs can show acceptable consistency ratings, but no DHT can show no lookup inconsistency during churn. We chose to use a structural prevention strategy to remove inconsistent lookup on the basis that inconsistent lookups are a result of inconsistency in routing tables. We define consistent lookup as

This master thesis investigates if customer churn can be predicted at the Swedish CRM-system provider Lundalogik.

If churn can be predicted, the company can target their resources to those customers and hopefully keep them. Finding the customers likely to churn is done through mining Lundalogik's customer database to find patterns that results in churn. Customer attributes considered relevant for the analysis are collected and prepared for mining. In ad

To predict churn relatively simple out of the box models, such as support vector machines and random forests, are used to achieve an acceptable outcome. To be on par with the models used for churn prediction in subscription based services, this report concludes that more research has to be done using more effective evaluation metrics. Finally

This past decade, the majority of services have been digitalized and data more and more available, easy to store and to process in order to understand customers behaviors. In order to be leaders in their proper industries, subscription-based businesses must focus on their Customer Relationship Management and in particular churn management, that is understanding customers cancelling their subscription. In this thesis, churn analysis is performed on real life data from a Software as a Service (SaaS) company selling an advanced cloud-based business phone system, Aircall. This use case has the par

Este trabalho foi realizado na cidade de Bragança com o intuito de estudar o efeito da melatonia, e de tratamentos progestagénicos associados à eCG na sincronização/indução do estro e, as melhorias reprodutivas desencadeados pelos mesmos. Quanto aos progestagénios foram utilizadas esponjas intravaginais impregnadas em acetato de fluorogestrona (FGA), compararam-se também os resultados obtidos quanto ao momento da administração da eCG, 24h antes ou no momento da retirada das esponjas. No ensaio, foram utilizadas 94 ovelhas da raça Churra Galega Bragançana. Em 25 delas foram colocados implantes

Churn analysis can be understood as a problem of predicting and understanding abandonment of use of a product or service. Different industries ranging from entertainment to financial investment, and cloud providers make use of digital platforms where their users access their product offerings. Usage often leads to behavioural trails being left behind. These trails can then be mined to understand them better, improve the product or service, and to predict churn. In this thesis, we perform churn analysis on a reallife data set from a music streaming service, Spotify AB, with different signals, r

Customer churn management is very important for companies, but many studies focus on improving the accuracy of predictive models. A churn prediction models lacks a matching strategy, making it difficult to select target customers according to corporate goals. Therefore, the study adopts the profit maximization retention strategy for customer churn management, taking the telecommunicatio

To survive or maintain an advantage in such a competitive marketplace, many telecommunications companies are turning to data mining techniques to resolve such challenging issues as fraud detection, customer retention, and prospect profiling.

With the large adoption of Internet customers became more aware of existing services and their prices. From the perspective of companies acquiring a new customer is more expensive than maintaining existing ones. In this sense, companies began to address the challenge of leaving customers to other companies. Customer churn is even more challenging in the telecommunications sector, because customers can change operator faster due to shorter loyalty period and easy migration service to other telecommunications operators without associated costs. Anticipating churn is therefore a major conce

Evaluation and comparisson of multiple algorithms to detect churn in telecom companies.<br>Telecommunication companies are acknowledging the existing connection between customer satisfaction and company revenues. Customer churn in telecom refers to a customer that ceases his relationship with a company. Besides losing the customer, it is also likely that the customer will join a competitor company.
