Credit Card Fraud Detection PSO in Python Projects
Abstract
Credit card fraud poses a significant threat to the financial industry, leading to major monetary losses and affecting customer trust. Detecting fraudulent transactions efficiently and accurately is crucial to safeguard financial operations. This project implements a Python-based credit card fraud detection system using Particle Swarm Optimization (PSO) to optimize feature selection and enhance classification accuracy. By analyzing transactional data, identifying anomalous patterns, and selecting the most relevant features, the system improves fraud detection while reducing computational complexity. The approach combines PSO with machine learning classifiers to detect fraudulent transactions with high precision and recall, enabling real-time monitoring and minimizing false positives. This methodology ensures robust and intelligent fraud detection suitable for modern banking systems.
Existing System
Traditional credit card fraud detection methods rely on manual monitoring, rule-based systems, or basic statistical techniques. While effective for simple fraud patterns, these approaches often fail to detect complex or evolving fraudulent activities. Conventional machine learning models, such as Support Vector Machines (SVM), Decision Trees, and Random Forests, have been applied to fraud detection, but they struggle with high-dimensional data and class imbalance, where fraudulent transactions are rare. Additionally, existing systems rarely implement optimization techniques for feature selection, leading to reduced model efficiency, longer training times, and higher chances of misclassification. As a result, current methods often provide suboptimal accuracy and are unable to perform effective real-time fraud detection.
Proposed System
The proposed system integrates Particle Swarm Optimization (PSO) with machine learning to improve credit card fraud detection in Python. PSO is used to identify the most significant features from the transactional dataset, reducing dimensionality and improving classifier performance. Selected features are fed into supervised learning algorithms such as Random Forest, XGBoost, or Gradient Boosting to classify transactions as legitimate or fraudulent. The system also addresses class imbalance using techniques like SMOTE (Synthetic Minority Over-sampling Technique) to enhance detection of rare fraudulent events. Python libraries including Pandas, NumPy, Scikit-learn, and PySwarms are used for data preprocessing, PSO implementation, model training, and evaluation. By optimizing feature selection and combining it with robust classifiers, the system achieves higher accuracy, reduced false positives, and real-time fraud detection. This ensures secure financial transactions and effective risk management in banking systems.
