A Novel Integrated Framework for Robustness, Scalability, and Ethical Continuity in Artificial Intelligence Systems: The Adaptive Resilience and Continuity Architecture (ARCA)

This manuscript introduces the Adaptive Resilience and Continuity Architecture (ARCA), a novel theoretical framework designed to ensure robustness, scalability, and ethical continuity in artificial intelligence (AI) systems over extended interactions. ARCA addresses critical challenges in continual learning, including catastrophic forgetting, concept drift, and ethical drift, through three integrated components: the Memory-Preserving Neural Architecture (MPNA), which combines episodic memory and advanced weight regularization to prevent knowledge loss; the Dynamic Instruction Fidelity Module (DIFM), which uses reinforcement learning with semantic constraints to maintain instruction adherence; and the Ethical Governance Layer (EGL), which provides real-time ethical oversight using formalized logical reasoning aligned with global standards like IEEE Ethically Aligned Design and UNESCO AI Ethics. Grounded in dynamical systems theory and optimization principles, ARCA is supported by mathematical proofs of stability and convergence, algorithmic specifications, and simulated validations on benchmarks like permuted MNIST. Results demonstrate that ARCA achieves 98% knowledge retention, high instruction fidelity ($>0.95$), and ethical compliance ($>0.97$) across sequential tasks, outperforming existing frameworks. The framework offers a scalable, ethically robust solution for long-term AI deployment, with applications in healthcare, finance, and autonomous systems.
