  • 摘要: 将聚类分析的损失函数引入到深度变换学习框架中,提出深度变换聚类分析模型,并使用交替向乘子算法对构建的模型进行并行交替求解。深度变换聚类分析模型在高光谱数据中基于空间分块进行波段筛选,并采用查表策略以确保聚类中心的鲁棒性。基于Indian Pines数据集和Pavia university数据集进行实验。结果表明,相比其他端到端深度学习方法,该方法在不同波段数量的情况下运行效率最优,并具有更好的总体准确度、平均准确度和Kappa系数。

     

    Abstract: This paper introduced the loss function of cluster analysis into the deep transform learning framework, proposed a deep transform cluster analysis model, and used the alternating multiplier algorithm to solve the constructed model in parallel. The deep transform clustering model selected bands based on spatial segmentation in hyperspectral data, and used the table lookup strategy to ensure the robustness of cluster center. Experiments were conducted based on Indian Pines dataset and Pavia university dataset. Compared with other end-to-end deep learning methods, the proposed method has the best operating efficiency under different band numbers, and has better overall accuracy, average accuracy and Kappa coefficient.
