In this paper, an improved Pinball Loss Fuzzy Support Vector Machine (Pin-FSVM) prediction model is proposed with the aim of improving the accuracy and efficiency of banks in the financial services industry in identifying potential customers to subscribe to time deposits. The Pin-FSVM model optimises the performance of the traditional fuzzy support vector machine by incorporating the concepts of the Pinball Loss Function and the Fuzzy Affiliation Degree. The model maintains prediction accuracy in noisy data environments and effectively handles the uncertainty in the data. In the application to the practice of predicting bank customers’ subscription deposits, Pin-FSVM successfully identifies customers who are more likely to choose time deposits, which significantly improves the prediction effect and provides a powerful tool for banks to accurately identify and serve their customer groups.展开更多
