Abstract
Predictive analytics increasingly relies on real-time, non-stationary data from healthcare, finance, cybersecurity, industrial automation, intelligent transportation, and IoT, where traditional machine learning models struggle to adapt to evolving data distributions. Continual Learning (CL), also known as lifelong or incremental learning, addresses these challenges by continuously learning new knowledge while preserving previously acquired knowledge, thereby mitigating catastrophic forgetting. This paper presents a unified continual learning framework for adaptive predictive analytics that integrates concept drift detection, adaptive feature representation, memory management, experience replay, regularization-based learning, and online model updating. The framework enables continuous adaptation to changing data while maintaining long-term predictive performance. Performance is evaluated using metrics such as prediction accuracy, precision, recall, F1-score, concept adaptation rate, forgetting rate, computational efficiency, and learning stability. Experimental results demonstrate that the proposed approach outperforms conventional static learning models by improving predictive accuracy, adaptability, and computational efficiency under dynamic conditions. The framework provides a scalable foundation for intelligent predictive systems with applications in fraud detection, predictive maintenance, medical diagnosis, cybersecurity, smart manufacturing, intelligent transportation, climate forecasting, and smart healthcare.
