We present a novel access control middleware for distributed multi-user review. The system uses a fuzzy inference system trained on real world access control rules to evaluate and select reviewers as an extension to a more traditional access control system. The method is intended for high security need specific requests, as a supplement to regular access control methods. In this way, it models a multi-person access system common in mechanical controls like missile launches, bank vault opening, and other high criticality domains. The proposed method improves security by increasing the number of compromised users needed to perform an attack, taking advantage of situational awareness of peer users in a system. We evaluate the proposed system with an example implementation based on a real-world organization, and show that the system can be used to effectively implement a secure resource access control system. Our work contributes to the growing body of research into fuzzy-logic access control, ML in access control, and multi-user authentication systems.

Offline reinforcement learning provides a viable approach to obtain advanced control strategies for dynamical systems, in particular when direct interaction with the environment is not available. In this paper, we introduce a conceptual extension for model-based policy search methods, called variable objective policy (VOP). With this approach, policies are trained to generalize efficiently over a variety of objectives, which parameterize the reward function. We demonstrate that by altering the objectives passed as input to the policy, users gain the freedom to adjust its behavior or re-balance optimization targets at runtime, without need for collecting additional observation batches or re-training.

There are significant challenges in designing optimization algorithms for constrained large-scale multiobjective optimization problems due to numerous decision variables and constraints. For example, the decision space size exponentially grows with the number of decision variables, and constraints restrict the feasible range, increasing the complexity of the search space. To solve these problems, this paper presents a constrained large-scale multiobjective optimization algorithm based on adaptive paired offspring generation (aPOCEA). Specifically, an adaptive parameter adjustment strategy is proposed to determine the number of solutions in each subpopulation and balance the exploration and exploitation ability of the algorithm, enhancing the convergence speed of aPOCEA. Meanwhile, we propose a parent selection strategy to select high-quality parent solutions, increasing the probability of generating high-quality offspring solutions. Experimental results on ten benchmarks, each with two to three objectives, multiple constraints, and hundreds of decision variables, demonstrate that aPOCEA outperforms other representative optimization algorithms.
In general a controlled system suffers from imprecise dynamic model which makes accurate trajectory tracking very difficult. Although the dynamic model can be fine tuned e.g., by using soft computing methods, but in o...

RGB-Thermal based pedestrian detection has received more extensive attention due to the provided detailed information and thermal sensitivity of pedestrians. In this paper, a single-modal feature augmentation network (SMA-Net) is proposed. Firstly, two single-modal branches are trained separately to optimize the feature extraction of each branch in addition to the training of pedestrian detection based on fused features. Secondly, a lightweight ROI pooling multiscale fusion module (PMSF) is proposed to obtain more fine-grained and abundant features, in which pooling features of different scales are integrated by adaptively weighting. Finally, a generative constraint strategy is designed to constrain fusion by minimizing the loss function between the generated fusion image and RGB-Thermal pairs. Experimental result on the challenging dataset KAIST demonstrates that the proposed SMA-Net achieves great performance in terms of accuracy and computational efficiency.
