However, existing robots in the market, with their fixed morphologies, face limitations when it comes to accessing confined spaces. Reconfigurable tiling robots provide a feasible solution to this challenge. By shapeshifting among the available morphologies to adapt to the different conditions of complex environments, these robots can enhance the efficiency of complete coverage. However, the ability to change shape is constrained by energy usage considerations. Hence, it is important to have an optimal strategy to generate a trajectory that covers confined areas with minimal reconfiguration actions while taking into account the finite set of possible shapes. This paper proposes a complete coverage planning (CCP) framework for a reconfigurable tiling robot called hTetrakis, which consists of three polyiamonds blocks. The CCP framework leverages Deep Reinforcement Learning (DRL) to derive an optimal action policy within a polyiamonds shape-based workspace. By maximizing cumulative rewards to optimize the overall kinetic energy-based costweight, the proposed DRL model plans the hTetrakis shapes and its trajectories simultaneously. To this end, the DRL model utilizes Convolutional Neural Networks (CNNs) with Long Short-Term Memory (LSTM) network and adopts the Actor–Critic deep reinforcement learning agent with Experience Replay (ACER) approach for off-policy decision-making. By producing trajectories with reduced costs and time, the proposed CCP framework surpasses conventional heuristic optimization methods like Particle Swarm Optimization (PSO), Differential Evolution (DE), Genetic Algorithm (GA) and Ant Colony Optimization (ACO) rely on tiling strategies.</div></div>","PeriodicalId":50523,"journal":{"name":"Engineering Applications of Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":7.5,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142535246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing research has overlooked the impact of cold load pickup on system restoration efforts. A sudden load spike can lead to the overloading of generators and transformers, which can result in the failure of the system restoration process. This study leverages the topological flexibility through dynamic microgrid formation of the system to mitigate the impact of cold load pickup, thereby enhancing the efficiency of sequential load restoration. To alleviate the computational complexity arising from intricate operational constraints and the uncertainties inherent in cold load pickup conditions, this paper proposes a novel model-free framework. Unlike existing deep reinforcement learning models, we incorporate physical constraint information into the model by means of physics-informed neural networks, where the solution of an optimization problem is regarded as knowledge, enabling the agent to learn operational constraints more efficiently and stably. The proposed approach is compatible with and can be integrated into any deep reinforcement learning algorithm that utilizes the advantage actor–critic framework with neural networks.

In this paper, we present the reconstruction error based implicit regularization method (REbIRM) that regularizes CNNs at the loss layer. During each training iteration, the reconstruction errors introduced by the two-stage discriminative auto-encoder are used to sharpen the generalization ability of deep CNNs by improving the decision boundary. In the application process, the trained deep CNN is used for completing computed tomography (CT) diagnostics. The main clinical benefit of our approach is that it is domain independent, requiring no specialized knowledge, and can therefore be applied to different types of datasets. To the best of our knowledge, this is the first attempt to implicitly regularize CNNs based on the reconstruction errors. Finally, experimental results on three CT image classification datasets show that REbIRM can achieve impressive results and that, in conjunction with Dropout, it obtains the state-of-the-art performance. REbIRM is also robust to the selection of hyper-parameters and only has the sublinear influence on the convergence of deep CNNs. Besides, empirical and theoretical evidence are provided to indicate that REbIRM prefers to converges in a constrained parameter space with flatter minima, which explains why it can generalize to new data.

It integrates prior information through a defect refinement module and a fusion module, fusing prior decoder features with corresponding one.

Loose particle detection is crucial. For sealed electronic equipment with large scale and complex structure, loose particle detection should not only include the judgment of existence, but also obtain location and material information to facilitate the cleaning and control work. In this paper, the authors proposed a multi-source information fused loose particle localization and material identification method. Firstly, the equipment model was designed, the loose particle samples were made, and loose particle signals were collected. Secondly, the two-stage adaptive energy threshold pulse extraction algorithm was newly proposed to extract effective pulses, and the threshold-judgement-search pulse matching algorithm was improved to match the effective pulse groups. Next, spectrograms were transformed from effective pulses to create the localization and material image set. The time-domain, frequency-domain and gray-level co-occurrence matrix features were used to construct the joint feature library. Then, the channel-weighting feature selection method was used to create the localization and material data set. Finally, PReLU-VGG19-Plus was trained on the localization and material image set to obtain the optimal localization and material neural network, while parameter-optimized XGBoost was trained on the localization and material data set to obtain the optimal localization and material classifier. On this basis, combined with the triple majority voting process, the combined localization and material framework were constructed. Extensive test results show that, the location-identification achieved by combined localization framework and the material-identification accuracy achieved by combined material framework are all 100%.

The proposed framework learns the dynamic-based features that are sensitive to damage and also invariant to different railway tracks. It comprises three components: data pre-processing, UDA implementation, and damage diagnosis. The framework uses the data from the source domain, including corresponding labels, as well as the unlabelled data from the target domain as input. The outputs of the framework consist of the predicted labels for the target domain. The performance of the proposed framework is evaluated using a comprehensive dataset of field measurements of a high-speed train passing 4 different lines within the French high-speed rail network.

Presently, major companies such as Tesla, Waymo, Uber, and Volkswagen Group (VW) leverage neural networks for advanced perception and autonomous decision-making. However, concerns have been raised about the escalating computational requirements of training these neural models, primarily in terms of energy consumption and environmental impact. In the situation of optimisation and sustainability, Spiking Neural Networks (SNNs), inspired by the temporal processing of the human brain, have come forth as a third-generation of neural networks, famed for their energy efficiency, potential for handling real-time driving scenarios and processing temporal information efficiently. However, SNNs have not yet achieved the performance levels of their predecessors in critical AD tasks, partly due to the intricate dynamics of neurons, their non-differentiable spike operations, and the lack of specialised benchmark workloads and datasets, among others. This paper examines the principles, models, learning rules, and recent advancements of SNNs in the AD domain. Neuromorphic hardware, hand in hand with SNNs, shows potential but has challenges in accessibility, cost, integration, and scalability.
