However, some people say that they are happy with their online banking experience. This work tries to address this critique and give the right advice to the customer. Customer satisfaction and frustration with online banking have been predicted using Machine Learning techniques in this study. Seven traditional machine learning classification algorithms Logistic Regression, Random Forest, Naïve Bayes, support vector machine, Neural network, Decision tree, K nearest neighbor algorithms to complete this research work and find the concluded delimiter.
