Comparison Of Machine Learning Techniques Credit card fraud is an act of criminal dishonesty. This paper. This paper has various machine learning algorithms. All these techniques are tested based on accuracy and precision. We have selected supervised learning technique Random Forest to classify the alert as fraudulent or authorized. This classifier will be trained using feedback and delayed supervised samples. Next it will aggregate each probability to detect alerts. Further we proposed a learning to rank approach where alerts will be ranked based on priority. The suggested method will be able to solve the class imbalance and concept drift problem. Future work will include applying semi-supervised learning methods for classification of alerts in fraud detection systems.

After the feature selection, the data will be sent to the algorithm which is the combination of the logistic regression, decision tree, random forest & MCC. The resultant data is stored in test sample data. The prediction of outcome is done Based on test sample data & the result of the combined algorithm. Later the performance & accuracy results are plotted. It has a feature which validates the results if the transaction is legitimate then the transaction is said to be true or else it is false. In case of false transactions the bank is made aware of it. A. System Architecture We have gathered data from the kaggle website. The dataset is trained and tested using the following techniques: logistic regression, random forests with decision trees, xgboost, isolation forest and confusion matrix . If our algorithm is applied into bank credit card fraud detection systems, the probability of fraud transactions can be predicted soon after credit card transaction occurs. Thereafter a series of anti-fraud strategies can be adopted to prevent banks from great losses and reduce risks.

Isolation forest is an anomaly detection algorithm. It detects anomalies using isolation, rather than modeling the normal points. Following is the result after implementing the isolation forest algorithm on our dataset
