  • 引入注意力机制动态加权多维重力特征,自适应融合
  • 在超1万点数据集上测试,显著提升各类模型校准准确率
  • 适合海洋工程、地质勘探等复杂环境下的高精度校准需求

重力适应区的精确校准在水下导航、地球物理勘探和海洋工程中具有重要意义。随着重力场数据应用日益广泛,基于单一特征的传统校准方法难以捕捉重力场的复杂特性及多维数据间的复杂关系。本文提出一种基于注意力机制的重力适应区校准算法,通过引入注意力机制,自适应融合多维重力场特征并动态分配权重,有效解决了传统特征选择方法中存在的共线性与冗余问题,显著提升了校准精度与鲁棒性。此外,构建了包含超过10,000个采样点的大规模重力场数据集,并采用Kriging插值提升数据空间分辨率,为模型训练与评估提供可靠数据基础。在多种经典机器学习模型(如SVM、GBDT、RF)上进行定性与定量实验,结果表明所提算法在各模型上均显著优于传统特征选择方法。该方法为重力适应区校准提供了新思路,展现出强泛化能力,在复杂环境中具有广泛应用潜力。代码已公开于https://github.com/hulnifox/RF-ATTN。

原文摘要 · Abstract (English)

Accurate calibration of gravity adaptation zones is of great significance in fields such as underwater navigation, geophysical exploration, and marine engineering. With the increasing application of gravity field data in these areas, traditional calibration methods based on single features are becoming inadequate for capturing the complex characteristics of gravity fields and addressing the intricate interrelationships among multidimensional data. This paper proposes an attention-enhanced algorithm for gravity adaptation zone calibration. By introducing an attention mechanism, the algorithm adaptively fuses multidimensional gravity field features and dynamically assigns feature weights, effectively solving the problems of multicollinearity and redundancy inherent in traditional feature selection methods, significantly improving calibration accuracy and robustness.In addition, a large-scale gravity field dataset with over 10,000 sampling points was constructed, and Kriging interpolation was used to enhance the spatial resolution of the data, providing a reliable data foundation for model training and evaluation. We conducted both qualitative and quantitative experiments on several classical machine learning models (such as SVM, GBDT, and RF), and the results demonstrate that the proposed algorithm significantly improves performance across these models, outperforming other traditional feature selection methods. The method proposed in this paper provides a new solution for gravity adaptation zone calibration, showing strong generalization ability and potential for application in complex environments.
