However, existing approaches for automated synthesis of mechanisms are either inefficient or prone to a loss of optimal solutions. To fill this gap, a systematic online decision-making method using Thompson Sampling (TS) based Monte Carlo Tree Search (MCTS) for automated conceptual design of mechanisms is proposed. The functional transformation relationships between inputs and outputs of the intended mechanism system are used to determine combinatorial patterns. Then, a functional representation model is constructed based on the combination rules of motion features and the inference relationships of function elements to represent a range of primitive mechanisms as fundamental building blocks. Finally, the optimal action selection strategy based on TS is applied into MCTS to develop Dirichlet based Monte Carlo Tree Search (D-MCTS) algorithm for searching mechanism building blocks. In addition, the conceptual design of the beat-up mechanism as well as the stitching and feeding mechanism are conducted to validate the feasibility of the proposed approach. Compared with specialized heuristics, D-MCTS achieves higher efficiency in finding the best combination of mechanism building blocks. Compared with other common algorithms, D-MCTS can always avoid the local optima trap to find the global optimal solution without any necessary hyper-parameter tuning. The proposed method exhibits a more balanced performance in exploration and exploitation, which provides better solutions for mechanism synthesis of given requirements.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"170 ","pages":"Article 112659"},"PeriodicalIF":7.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143213402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The limited availability of strong ground motion records (peak ground acceleration (PGA) > 100 gal) limits the application of machine learning techniques in this domain. In this study, we utilized the KiK-net database to identify three site parameters—<em>V</em><sub>S30</sub>, <em>V</em><sub>S-Zhole</sub>, and borehole depth—corresponding to the peak underground acceleration (PUA) on the downhole and spectral acceleration (Sa) across 15 different periods as input features for the machine learning model. The output parameters were PGA and Sa across 15 different periods. Pairs of strong ground motion records (PGA > 100 gal) are extracted from the original KiK-net database and processed using a conditional generative adversarial network (cGAN) model to synthesize ground motion parameters, then the original KiK-net database is supplemented. Regression prediction tests were performed on both the original and augmented databases and evaluated using three regression metrics: root mean square error (RMSE), mean absolute error (MAE), and R<sup>2</sup>. The findings indicate that the model trained with synthetic data generated by the cGAN enhances the prediction accuracy of ground motion parameters. A comparative analysis of the ground motion amplification coefficients between station records and cGAN-generated data across various spectral periods was performed. The amplification coefficients across different spectral periods aligned with the ground-motion records, thereby validating the reliability of the cGAN-generated synthetic ground-motion data from a seismological perspective.

Nature-inspired algorithms (NIAs), which can somehow reduce the reliance on initial points, function differentiability, and convexity, with gradient-free nature and ease of implementation, have been actively applied in RLV reentry trajectory optimization problems. As NIAs are primarily designed for unconstrained optimization, constraint-handling techniques (CHTs), which play a crucial role in addressing RLV trajectory optimization issues and significantly impact the overall quality of the solutions, are necessary to guide the search towards feasible regions. However, the existing literature has not yet, or at least not systematically, investigated how well the current CHTs perform.

Therefore, this paper proposes a dynamic Q&A multi-label classification approach based on adaptive multi-scale feature extraction. First, global and local semantic features of Q&As are extracted based on bidirectional long short-term memory network and convolutional neural network models, respectively. Second, the label features extraction and fusion method is proposed. The semantic features of the labels are extracted, the label structure graph based on horizontal and vertical dependencies is constructed, and the label structure and semantic features are fused using the graph attention network integrating multi-head self-attention mechanism. Afterward, the label-aware local features of Q&As are constructed using the attention mechanism and fused with global features of Q&A using the multi-head self-attention, thereby multi-scale fusion classification features of Q&A are established. Then, to adaptively extract the core multi-scale fusion features, a multi-objective feature selection model is established and an improved binary multi-objective Sinh Cosh optimizer algorithm is proposed to solve the model.

To address this issue, this work explores the fundamental problems in current U-Net architecture-based SOD models from the perspective of image spatial frequency decomposition and synthesis. A concise and efficient Frequency-Guided Network (TFGNet) is proposed that simultaneously learns the boundary details (high-spatial frequency) and inner regions (low-spatial frequency) of salient regions in two separate branches. Each branch utilizes a Multiscale Frequency Feature Enhancement (FFE) module to learn pixel-wise frequency features and a Transformer-based decoder to learn mask-wise frequency features, improving a comprehensive understanding of salient regions. TFGNet eliminates the need to exchange global and local features at intermediate layers of the two branches, thereby reducing interference from erroneous information. A hybrid loss function is also proposed to combine BCE, IoU, and Histogram dissimilarity to ensure pixel accuracy, structural integrity, and frequency distribution consistency between ground truth and predicted saliency maps.
