Most existing methods assume that the sensor types of inputs are consistent in the training and testing datasets. However, in practice, sensor failure or the lack of corresponding sensors installed on the equipment can cause the model to fail due to incomplete input information, which ultimately leads to monitoring interruption. Therefore, developing an effective diagnostic knowledge transfer mechanism is essential. To address fault monitoring interruptions caused by the absence of the single sensor, this study proposes a monitoring substitution framework via dual-stream reconstruction and joint representation for fault diagnosis. Dual-stream joint alignment framework (DSJA) designs unique feature extraction models according to the characteristics of each signal, and introduces locality-sensitive latent diffusion space (LSLDS) for feature reconstruction. Building on this foundation, joint representation of feature consistency and domain invariance is developed to effectively map and align feature spaces across different modalities. The monitoring-substitution of the two signals is validated using gradient-based class activation map (Grad-CAM) visualization, and the diagnostic and monitoring-substitution performance of the proposed method is assessed across four scenarios. Compared with existing methods, the proposed approach demonstrates superior fault diagnosis and monitoring-substitution capabilities.</div></div>","PeriodicalId":19268,"journal":{"name":"Neurocomputing","volume":"659 ","pages":"Article 131785"},"PeriodicalIF":6.5,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145326701","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}

Although plenty of defect repositories exist, they often fail to capture the context of inter-procedural defects, which include all methods in the propagation path from the defect-source method to the defect-triggering method. This limitation is particularly critical for the Null Pointer Exception (NPE), a common defect that often propagates across multiple methods in Java systems. To address this problem, we propose a novel and automatic approach, called <i>JDExtractor</i>, to extract defect-related methods from real applications. The main challenge is how to identify all defect-related methods efficiently and accurately. <i>JDExtractor</i> tackles this challenge by constructing a method-level data graph using the principle of Java type compatibility and simplifying the data graph using filtering criteria. Data flow analysis helps construct a coarse-grained method-level data graph, which reflects the potential patterns of inter-procedural data interaction, thereby ensuring analysis efficiency. Afterward, filtering analysis simplifies the data graph based on the propagation properties of inter-procedural defects, thus ensuring analysis accuracy. Evaluation results suggest that both the static slicing tool WALA and the dynamic slicing tool Slicer4J yield several false positives, whereas <i>JDExtractor</i> successfully extracts defect-related methods and defect propagation paths with fewer false positives in a short time. Moreover, <i>JDExtractor</i> has been applied to open source projects on GitHub, ultimately extracting defect-related methods for 67 defects from 319 compiled open source applications.</p></div>","PeriodicalId":55414,"journal":{"name":"Automated Software Engineering","volume":"33 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316538","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, interference poses a significant challenge in such systems, occurring when multiple transmitters and receivers operate in the same frequency band. This interference hampers communication efficiency and necessitates sophisticated signal-processing techniques for mitigation. Interference cancelation techniques, particularly in Massive MIMO wireless communication systems, play a crucial role in reducing the impact of interference caused by multiple transmissions from different users. This paper proposes the utilization of the Kronecker product-constrained least-mean-square (KCLMS) algorithm to nullify interference and employs the adaptive Kalman filtering approach to further minimize interference effects. Simulation results demonstrate that the proposed KCLMS + adaptive Kalman method achieves superior performance, with an RMSE of 0.045, PCC of 0.980, and SIR of 32.0 dB, outperforming transformer, DNN, CNN-LSTM, and traditional filtering methods. Additionally, it exhibits high performance-to-cost efficiency with moderate computational time (0.84 ms per iteration) and memory usage (13.5 MB), making it a practical solution for efficient, interference-resilient wireless communications. Performance validation is conducted using subjective tests, with evaluation metrics like Pearson correlation coefficient (PCC) and root mean square error (RMSE) to demonstrate the improved outcome.

This paper proposes a hybrid <i>M3IF</i> where input medical images are decomposed using stationary wavelet transform (SWT) into low-frequency components (LFCs) and high-frequency components (HFCs). The LFCs and HFCs are fused using energy- and contrast-based metrics. And later reconstruction is performed using inverse SWT (ISWT). The total variation minimization (TVM) using Chambolle's algorithm is applied as a post-refinement operation to reduce noise and preserves the fine details. In this paper, the proposed methodology is termed as M3IF-(SWT-TVC), Here, the acronym TVC is the combination of TVM using Chambolle's algorithm. TVM refinement process is an iterative approach, with the fusion outcomes of M3IF-(SWT-TVC) assessed over a predefined 100 iterations. The TVM, and SWT are blended to balance smoothness and structural details. The final fusion results obtained through M3IF-(SWT-TVC) are evaluated against several prominent non-traditional methods.

Viewpoints are then generated based on this mesh. Additionally, the triangles within the depth camera's field of view for each viewpoint are determined. The set covering problem (SCP) accepts the set of triangles covered by each viewpoint and reduces the number of viewpoints to decrease the flight distance and time. Finally, the coverage route that includes all the selected viewpoints is defined as the solution to the traveling salesman problem (TSP).
