While Large Language Models (LLMs) have shown proficiency in various domains, their application in product design remains limited, often resulting in generic outputs. To address this, we propose an innovative paradigm for intelligent product design generation, termed ProdGen. The core of ProdGen is the ProdGen-Agent system, which integrates LLMs with customized expert design tools, leveraging the proposed Multi-Design Task Adapter (MDT-A) method and a Dual Knowledge Enhancement Mechanism. The MDT-A method injects multimodal design task knowledge into LLMs through a unified knowledge fusion framework, enabling enhanced task decomposition and efficient interaction with custom design tools. The Dual Knowledge Enhancement Mechanism enriches LLM performance by incorporating domain-specific knowledge bases and structured graph-based data retrieval, ensuring more accurate and relevant design outputs. Demonstrated through kitchen design cases, ProdGen-Agent autonomously handles the entire design process, excelling in user need analysis, task breakdown, decision-making support, tool integration, and multidimensional design generation. Expert evaluations validate ProdGen-Agent’s effectiveness in automating complex design tasks, confirming its potential to revolutionize product design processes across various industries by leveraging LLMs in combination with domain expertise.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"176 ","pages":"Article 113147"},"PeriodicalIF":7.2,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143854813","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}

Secondly, a decision variable, \"improvement rate\" is introduced to determine service defects among service quality characteristics and quantify their improvement degrees. Based on this decision variable, a multi-objective optimization model is constructed to derive optimal improvement strategies aligned with customer expectations. Finally, the proposed methodology is illustrated with a case study regarding a FPID company of China, and its efficiency and advantages are verified via comparative analysis.

Semi-supervised incremental learning enables continuous learning of new fault classes in an open environment, relying on a small number of labeled samples and a certain number of unlabeled samples. To address the semi-supervised incremental learning problem of fault classes, semi-supervised feature contrast (SSFC) is proposed, a new approach for bearing fault diagnosis with limited labeled samples.

However, privacy concerns become critical when model inference involves separate ownership of data and model parameters. Existing MPC-based methods for private inference suffer from significant overhead and high latency, where replacing traditional Softmax attention mechanisms with faster alternatives serves as a promising research direction. To achieve a better balance between Transformer model performance and inference speed, we explore the impact of attention mechanisms and attention heads on model performance. First, we found that the performance of the attention mechanism is closely related to the downstream task dataset, and the attention mechanism that is faster on specific datasets can actually achieve better model performance. Additionally, we discovered that for attention mechanisms that experience a performance decline, appropriately restoring the attention heads of the Softmax mechanism can significantly enhance performance. We further observed that the selection of key attention heads under different mechanisms is consistent, providing a basis for designing search strategies adapted to different scenarios. Based on these findings, we propose an MPC-friendly attention mechanism replacement method that enables Transformer private inference to be more efficient and performant. This method incorporates two strategies for selecting and replacing attention mechanisms to address diverse scenario requirements, and the resulting heterogeneous attention mechanism significantly improves the speed of private inference while maximizing model performance. With experiments on different downstream tasks, we demonstrated that our method improves average model performance by 1.94 % compared to standard pre-training models, with an inference speed increase of approximately 3 × .

However, existing TKGs are far from complete, and their incompleteness significantly affects the performance of downstream applications. Therefore, Temporal Knowledge Graph Completion (TKGC) has become a current research hotspot, which aims to reason potential missing facts based on existing ones. In the widely studied TKGC methods with the implicit representation of temporal information, existing methods that embed temporal information into entity representations can capture the temporal evolution of entities. However, they fail to take the behavioral characteristics of entities across different time units into account, making them challenging to precisely model the fine-grained dynamics of entities. Furthermore, given the powerful expressiveness of Convolutional Neural Networks (CNNs), some TKGC methods have employed the 1D convolution operation to capture global relationships within the embedded quadruple, enabling the learning of explicit knowledge in TKGs and attaining competitive performance for TKGC. Nevertheless, the non-linear and deep features embedded in the entity-relation interaction have not been insufficiently explored. To address these challenges, this paper proposes JointDE, a TKGC model that applies both 1D and 2D convolution operations to the generated diachronic entity embedding, which simultaneously learns the explicit and implicit knowledge in TKGs. The new diachronic entity embedding method explicitly models the inherent attributes of entities and integrates temporal features across different time units, thereby possessing the ability to capture fine-grained entity evolution. More importantly, we construct feature matrices and filters using diachronic entity embeddings and relation embeddings, leveraging an internal 2D convolution mechanism to expand their interactions. This is the first work to learn implicit knowledge embedded in TKGs from a local relationship perspective for TKGC. Experimental results demonstrate that JointDE surpasses several TKGC baseline methods and achieves state-of-the-art performance on three event-based benchmark datasets: ICEWS14, ICEWS05–15, and GDELT.
