ML Models
ML algorithms like RF, SVM, DT, GNB, LR, and LC are pivotal in CCFD. They enable computers to learn from data, classify transactions, and identify anomalous patterns. While effective, they face challenges with data imbalance, scalability, and interpretability in real-time applications.
Benefits:
- High accuracy in classification tasks
- Adaptable to evolving fraud patterns
- Effective for structured data
Challenges:
- Difficulty with highly imbalanced datasets
- Scalability issues with massive real-time data
- Computational demands for training and deployment
DL Models
DL, utilizing neural networks like CNNs, RNNs, LSTMs, and VAEs, excels at processing large, complex datasets for CCFD. These models learn intricate, non-linear relationships and temporal dependencies, offering advanced threat detection capabilities.
Benefits:
- Exceptional for complex, high-dimensional data
- Captures intricate non-linear relationships
- Strong performance in sequence prediction
Challenges:
- High computational complexity and resource demands
- Prone to overfitting with limited or imbalanced data
- Requires large labeled datasets for optimal training
MHO Algorithms
Meta-heuristic optimization algorithms (e.g., Genetic Algorithm, Particle Swarm Optimization) are inspired by natural processes. They are used to optimize ML/DL models by exploring search spaces efficiently, improving feature selection, and enhancing detection rates in complex, dynamic environments.
Benefits:
- Optimizes model parameters for better accuracy
- Automates detection parameter adjustments
- Effective in avoiding local optima and exploring search space
Challenges:
- Computationally intensive for large datasets
- Parameter sensitivity requires expertise
- Scalability issues for real-time scenarios
