Abstract :

It is vital that credit card companies are able to identify fraudulent credit card transactions so that customers are not charged for items that they did not purchase. Such problems can be tackled with Data Science and its importance, along with Machine Learning, cannot be overstated. The Credit Card Fraud Detection Problem includes modeling past credit card transactions with the data of the ones that turned out to be fraud. Our objective here is to detect 100% of the fraudulent transactions while minimizing the incorrect fraud classifications. This model is then used to recognize whether a new transaction is fraudulent or not. Credit Card Fraud Detection is a typical sample of classification. In this process, we have focused on analyzing and pre-processing data sets as well as the deployment of multiple anomaly detection algorithms such as Local Outlier Factor and Isolation Forest algorithm on the PCA transformed Credit Card Transaction data. This project intends to illustrate the modeling of a data set using machine learning with Credit Card Fraud Detection.
