4.Support Vector Machine
SVM propertoes:
- Belongs to the class of binary classifiers
- Well-suited for solving classification problems in high-dimensional spaces
- Handling complex decision boundaries
- The model can analyze various features and patterns associated with financial transactions
- Detect and classify patterns

- Dataset Selection
- Label Conversion
- Feature Selection
- Data Splitting
- Model Training
- Performance Evaluation
- Visualization
- SVM Model Training
- Pattern Learning
- Prediction Application
- Comparison with Actual Labels
- Decision Boundary
