Feature Selection: Choose features that are most informative and avoid the curse of dimensionality.
Model Interpretability: Ensure that the model's decisions are understandable and explainable.
Real-time Performance: Optimize the system for real-time processing of network traffic.
Evolving Threats: Stay updated with emerging attack techniques and adapt the system accordingly.
Future Enhancements
