Handling Imbalanced Dataset Using Cost Sensitive Neural Networks Credit Card Fraud Detection

Credit Card Fraud Detection Using Artificial Neural Network Pdf To test the performance of the hnn cuhit in credit card fraud detection, we use a real dataset from a city bank during sars cov2 in 2020 to conduct the experiments. In this project, several methods are explored for handling imbalanced data and performances are compared. for metric methods, the metrics to be trained by the neural network model are modified.

Pdf Credit Card Fraud Detection From Imbalanced Dataset Using Machine To detect a fraud detection, we can use machine learning, in which there are a lot of machine learning algorithm out there. in this project we will also see which machine learning models fits. Imbalanced data is crucial for contemporary machine learning models. evaluating the effectiveness of machine learning classifiers under an unfair dataset is problematic. several resampling techniques were applied to the unwarranted dataset and pre processing stages. This article proposes an efficient cost sensitive weak learner approach with a bagging and random forest classifier (cswlb) to minimize misclassification problems and overcome the class imbalance issue. Fraud detection is a critical task in finance and e commerce industries. however, the datasets involved are typically highly imbalanced, with fraudulent transactions being significantly outnumbered by legitimate ones. this project explores various techniques to handle this imbalance and improve model performance.

This study presents a comparative experimental approach to address the imbalance classification problem by employing several optimization and resampling methods to deal with imbalanced datasets. The study demonstrates how to model utilizing multiple classifiers and data balance using machine learning approaches to learning about credit card fraud detection. the data has been observed as an imbalanced dataset that could have inferred not much optimal performance of models. Achieving this task is very challenging, primarily due to the dynamic nature of fraud and also due to lack of dataset for researchers. this paper presents a review of improved credit card. To accomplish this task, we use self organizing maps, which are a special type of artificial neural network. fid som is designed to address the challenge of dimensionality reduction in scenarios characterized by highly imbalanced data.
