Multi-Class Classification for Predicting Customer Satisfaction : Application of machine learning methods to predict customer satisfaction at IKEA

Sammanfattning: Gaining a comprehensive understanding of the features that contribute to customer satisfaction after contact with IKEA’s Remote Customer Meeting Points (RCMPs) is essential for implementing effective remedial measures in the future. The aim of this project is to investigate if it is possible to find key features that influence customer satisfaction and to use these to predict customer satisfaction. The task has been approached as a multi-class classification problem, with the objective of classifying the observations into five distinct levels of customer satisfaction. The study utilized three models, Multinomial Logistic Regression, Random Forest, and Extreme Gradient Boosting, to investigate these possibilities. Based on the methods used and the available data, the results indicate that it is currently not feasible to accurately identify key features or predict customer satisfaction.
