Special Issue Information

DearColleagues,

The last few decades have seen the emergence of a new era of intelligent sensors, enabling the creation of systems and devices that improve the convenience and quality of our lives and radically change the way people perceive and understand the world. Remarkable advances in machine learning and signal processing technologies now enable us to collect, analyse, and interpret information from a wide range of intelligent sensors in a variety of applications. This has a significant impact on a wide range of areas, including computer vision systems, target tracking, object recognition, medical imaging, health monitoring, control and robotics, security systems, production quality control, autonomous vehicles, intelligent transportation systems, intelligent homes, and many others.

This Special Issue calls for innovative efforts to explore new frontiers and challenges in the application of machine learning techniques and algorithms to many areas of intelligent sensing applications.

Topics of interest include, but are not limited to, the following:

  • Intelligent sensors and systems in machine vision and control;
  • Machine learning methods for health monitoring and biomedical signal processing;
  • Pattern recognition in medical diagnosis;
  • AI-based transportation systems;
  • Deep learning architectures;
  • Data-driven models;
  • Machine learning in various sensing applications;

Unmanned platforms such as unmanned aerial vehicles, unmanned ground vehicles, and autonomous underwater vehicles often face challenges of data, device, and model heterogeneity when performing collaborative data processing tasks. Existing research does not simultaneously address issues from these three aspects. To address this issue, this study designs an unmanned platform cluster architecture inspired by the cloud-edge-end model. This architecture integrates federated learning for privacy protection, leverages the advantages of distributed model training, and utilizes edge computing’s near-source data processing capabilities. Additionally, this paper proposes a federated edge intelligence method (DSIA-FEI), which comprises two key components. Based on traditional federated learning, a data sharing mechanism is introduced, in which data is extracted from edge-side platforms and placed into a data sharing platform to form a public dataset. At the beginning of model training, random sampling is conducted from the public dataset and distributed to each unmanned platform, so as to mitigate the impact of data distribution heterogeneity and class imbalance during collaborative data processing in unmanned platforms. Moreover, an intelligent model aggregation strategy based on similarity measurement and loss gradient is developed. This strategy maps heterogeneous model parameters to a unified space via hierarchical parameter alignment, and evaluates the similarity between local and global models of edge devices in real-time, along with the loss gradient, to select the optimal model for global aggregation, reducing the influence of device and model heterogeneity on cooperative learning of unmanned platform swarms. This study carried out extensive validation on multiple datasets, and the experimental results showed that the accuracy of the DSIA-FEI proposed in this paper reaches 0.91, 0.91, 0.88, and 0.87 on the FEMNIST, FEAIR, EuroSAT, and RSSCN7 datasets, respectively, which is more than 10% higher than the baseline method. In addition, the number of communication rounds is reduced by more than 40%, which is better than the existing mainstream methods, and the effectiveness of the proposed method is verified.
