ANSR-DT: A Neuro-Symbolic Framework for Adaptive and Explainable Digital Twins
Researchers have introduced ANSR-DT, a novel neuro-symbolic framework designed to enhance digital twins for industrial applications. This framework integrates temporal anomaly detection, symbolic reasoning, and reinforcement learning to improve interpretability, adaptability, and the incorporation of domain knowledge. ANSR-DT combines a CNN-LSTM model for pattern recognition with Prolog-based reasoning to generate explicit rules and traceable decision paths, further refined by a PPO-based adaptation layer. Experimental results demonstrate that ANSR-DT achieves competitive predictive performance while offering stable rule extraction and scalable reasoning, outperforming eight baseline methods and validating on the Skoltech Anomaly Benchmark.
