Abstract

The present research evaluates the efficacy of several machine learning models in credit card fraud detection, employing data sets of 284,407 transactions produced from online platforms. Careful data processing includes cleansing, scaling, mechanical properties, data imbalance management, and transient characteristics After preprocessing, five models— Artificial Neural Network (ANN), Support Vector Machine (SVM), Random were trained Forest (RF), Decision Tree (DT), and Naive Bayes (NB)—were assessed. Notably, ANN demonstrated an amazing performance of 97.6% accuracy, followed closely by SVM 95.5%, RF 94.5%, DT 92.3%, and NB 88.9% with the confusion matrices indicating high accuracy, true negatives, false positives, and false positives of each sample. It also gave little insight into the capacity to effectively identify false negatives. While ANN exhibited a very accurate, balanced detection of fraudulent and valid transactions, DT-NB showed a number of misclassifications rising disclosure. These arise from careful selection of machine learning models for credit card fraud detection, micro -And underline the significance of integration, with factors such as accuracy, translation, computational economy, and the etc. included. The study offers the standards and principles required to construct powerful and comprehensive credit card fraud detection systems, leading to gains in financial security and continually improving fraud prevention tactics.
