Special Issue Information

Dear Colleagues,

The pervasive integration of deep learning (DL) and machine learning (ML) in engineering sensing technologies marks a significant paradigm shift, providing unparalleled advancements in sensor fabrication, deployment, and calibration. Machine learning algorithms now play a crucial role in optimizing sensor configurations for various applications, ensuring precision and efficiency from the onset of data collection. Deep learning contributes extensively to the development of intelligent calibration techniques, adapting to diverse environmental conditions and counteracting sensor degradation to maintain long-term reliability and accuracy. These advanced computational methods extend their influence to data refinement, offering solutions for enhancing data accuracy, interpolating missing values, and facilitating intelligent data classification and recognition. The predictive modelling capabilities of these techniques introduce possibilities for proactive maintenance and anomaly detection within engineering infrastructures, guaranteeing safety and enhancing the lifespan of vital equipment. Furthermore, these technologies are central to innovating new sensing modalities and methodologies, addressing the growing complexity and evolving demands of contemporary engineering challenges.

The aim of this Special Issue is to highlight and promote recent advancements in algorithm-assisted sensing and its applications within the engineering field, covering aspects from sensor pre-processing, data collection, and analysis to practical engineering applications utilizing machine learning and deep learning. We are interested in a variety of topics, including but not limited to:

  • Enhancing sensing accuracy with ML/DL;
  • ML/DL-supported sensor fabrication, deployment, and calibration;
  • Advanced data classification and prediction through ML/DL;
  • Applying ML/DL-assisted sensing in diverse engineering scenarios;
  • ML/DL algorithm optimization in engineering sensing;
  • Targeted optimization strategies for applying ML/DL in engineering scenarios.

In dynamic industrial environments, strategic sensor placement is key to accurately monitoring equipment and detecting critical events. Despite progress in Industry 4.0 and the Internet of Things, research on optimal sensor placement remains limited. This study addresses this gap by analyzing how sensor placement impacts event detection, using chemical detection as a case study with an open dataset. Detecting gases is challenging due to their dispersion. Effective algorithms and well-planned sensor locations are required for reliable results. Using deep convolutional neural networks (DCNNs) and decision tree (DT) methods, we implemented and tested detection models on a public dataset of chemical substances collected at five locations. In addition, we also implemented a multi-objective optimization approach based on the non-dominated sorting genetic algorithm II (NSGA-II) to identify optimal sensor configurations that balance high detection accuracy with cost efficiency in sensor deployment. Using the refined sensor placement, the DCNN model achieved 100% accuracy using only 30% of the available sensors. Full article

In recent years, there has been significant growth in the ubiquity and popularity of three-dimensional (3D) point clouds, with an increasing focus on the classification of 3D point clouds. To extract richer features from point clouds, many researchers have turned their attention to various point set regions and channels within irregular point clouds. However, this approach has limited capability in attending to crucial regions of interest in 3D point clouds and may overlook valuable information from neighboring features during feature aggregation. Therefore, this paper proposes a novel 3D point cloud classification method based on global attention and adaptive graph convolution (Att-AdaptNet). The method consists of two main branches: the first branch computes attention masks for each point, while the second branch employs adaptive graph convolution to extract global features from the point set. It dynamically learns features based on point interactions, generating adaptive kernels to effectively and precisely capture diverse relationships among points from different semantic parts. Experimental results demonstrate that the proposed model achieves 93.8% in overall accuracy and 90.8% in average accuracy on the ModeNet40 dataset. Full article
