Evaluating the Performance of Two Hybrid Feature Selection Model of Machine Learning for Credit Card Fraud Detection on Classification and Prediction Methods | Chapter 06 | Advances in Applied Science and Technology Vol. 2
The hybrid and non-hybrid feature
selection model aimed at predicting and classifying whether a transaction is
fraudulent or non-fraudulent using machine learning approaches. The objective
of this study was to use supervised learning framework to differentiate
fraudulent and genuine transactions. The proposed hybrid model utilizes feature
selection methods namely; the Principal Component Analysis (PCA) and
PCA-Backward elimination with multiple linear regression and Reduced Error
Pruning Tree classifier (RepT) using Python and WEKA. Through five experiments
carried out in this study, the proposed approach has proven to be effective for
eliminating redundant features in the dataset that does not have significant
impact using PCA and Backward elimination method to optimize the predictive
behaviour of the credit card transactions. Our first findings from the
experimental results revealed that the RepT with PCA-Backward-Elimination
prediction accuracy 87.37% is higher than that of multiple linear regressions
with PCA 73.35% and PCA-Backward-Elimination 73.34%. Our second findings also
revealed that the RepT with PCA-Backward-Elimination classification accuracy of
99.9368% is higher than that of multiple linear regressions with PCA 99.9122%
and PCA-Backward-Elimination 99.9105%. The performance metrics measures on the
classification model of the logistic regression with PCA-Backward-Elimination
indicates that the hybrid model negates it with the expectation of maximization
to minimization (99.9122% to 99.9105%) but returns the same results on the RepT
decision tree classification in both cases of
99.9368%. The proposed hybrid feature selection method with machine
learning algorithms outperforms the non-hybrid feature selection method with
machine learning algorithms for classification and prediction accuracy.
