This study addresses the limitations of conventional traffic sign assessment, which relies heavily on manual inspections and typically evaluates either daytime visibility or nighttime retroreflectivity in isolation, lacking an integrated approach. To bridge this gap, the authors propose the first unified evaluation framework that jointly quantifies daytime visual performance and nighttime retroreflective properties. Specifically, they fine-tune vision-language models—LLaVA, Qwen, and InternVL—to assess four key daytime visual factors and integrate these with LiDAR-derived retroreflectivity measurements to formulate a Sign Condition Index (SCI) for maintenance decision support. Experiments on 462 traffic signs demonstrate the framework’s effectiveness in identifying 68 signs requiring immediate replacement, with LLaVA and Qwen achieving the highest performance (bidirectional cosine similarity of 0.67–0.76), thereby validating the method’s accuracy and cost-efficiency.
This work addresses the challenges of similarity measurement and open-set recognition in polarimetric material classification by formulating the task as a point-matching problem. The authors propose a classical-quantum hybrid framework that maps Mueller matrices to 32-dimensional voxel embeddings via an encoder, representing them as probability amplitudes of quantum states. For the first time, a quantum SWAP-test circuit is employed to compute the fidelity between query samples and anchor points, which serves as the similarity score for open-set classification. Evaluated on a dataset comprising 23 material classes, the method achieves competitive classification accuracy and demonstrates strong open-set discrimination capability.
This work addresses the lack of interpretability in existing network intrusion detection systems and the inability of classical subgroup discovery methods to effectively uncover critical multi-feature interactions in high-dimensional spaces. The study pioneers a quantum optimization formulation of subgroup discovery by encoding feature selection into a QUBO (Quadratic Unconstrained Binary Optimization) model, integrating least-squares regression to approximate the WRAcc (Weighted Relative Accuracy) objective function. The resulting problem is solved using the Quantum Approximate Optimization Algorithm (QAOA) on IBM Quantum hardware (ibm_pittsburgh). In experiments with 10–25 qubits, the approach achieves WRAcc scores ranging from 0.624 to 0.983 and yields unique subgroups with test accuracy up to 99.6%, substantially outperforming classical beam search. Notably, it uncovers high-order interaction patterns previously pruned by greedy strategies, establishing a novel paradigm for quantum combinatorial optimization in cybersecurity tailored to NISQ-era devices.
