Credit Card Fraud Detection with Kaggle Dataset

Credit_Card_Fraud

Data science project:

• EDA on the dataset with visually appealing graphs
• Model built:
• 1. SVM with grid search for hyperparameters tuning
• 2. SVM with feature selection
• 3. SVM with SMOTE upsampling on the frauds
• 4. Random Forest with grid search for hyperparameter tuning
• 5. 3-layer ANN with Keras
• Metrics used: AUC, Precision, Recall
• Sample model results (for 3-layer ANN): AUC 98%, Precision 93%, Recall 74%
