Financial Data Analysis Using CNN With Feature Selection


Alhakam Salih and Hiren Joshi


Abstract: In the age of big data, the financial services industry generates massive volumes of complex and high-dimensional data that demand advanced analytical solutions. Convolutional Neural Networks (CNNs), originally developed for image analysis, have demonstrated strong capabilities in learning rich, hierarchical features directly from raw financial data, making them well-suited for tasks such as credit scoring, fraud detection, and risk assessment. This paper presents a proposed CNN model tailored for financial data analysis. The model efficiently captures the underlying patterns and nonlinear relationships within the data, which is considered one of the reasons for the model’s high accuracy. To further enhance performance, a feature selection (FS) step was integrated before training, enabling the model to focus on the most informative attributes. Experimental results on the Santander Customer Transaction Prediction dataset show that the proposed CNN model, when combined with feature selection, achieved a remarkable 100% accuracy in classification tasks. These findings underscore the potential of CNN-based frameworks, enhanced by targeted feature selection, to transform financial data analysis. The approach enables more accurate, scalable, and automated decision-making across critical financial sector applications.

Keywords: Convolutional Neural Network (CNN), Feature Selection, ANOVA, Mutual Information (MI), Chi-Square.
