Water resource accounting constitutes a fundamental approach for implementing sophisticated management of basin water resources. The quality of water plays a pivotal role in determining the liabilities associated with these resources. Evaluating the quality of water facilitates the computation of water resource liabilities during the accounting process. Traditional accounting methods rely on manual sorting and data analysis, which necessitate significant human effort. In order to address this issue, we leverage the remarkable feature extraction capabilities of convolutional operations to construct neural networks. Moreover, we introduce the self-attention mechanism module to propose an unsupervised deep clustering method. This method offers assistance in accounting tasks by automatically classifying the debt levels of water resources in distinct regions, thereby facilitating comprehensive water resource accounting. The methodology presented in this article underwent verification using three datasets: the United States Postal Service (USPS), Heterogeneity Human Activity Recognition (HHAR), and Association for Computing Machinery (ACM). The evaluation of Accuracy rate (ACC), Normalized Mutual Information (NMI), and Adjusted Rand Index (ARI) metrics yielded favorable results, surpassing those of K-means clustering, hierarchical clustering, and Density-based constraint extension (DCE). Specifically, the mean values of the evaluation metrics across the three datasets were 0.8474, 0.7582, and 0.7295, respectively.
水资源核算构成了实施流域水资源精细化管理的基本方法。水质在确定与这些资源相关的负债方面起着关键作用。评估水质有助于在核算过程中计算水资源负债。传统的核算方法依赖人工分类和数据分析,这需要大量人力。为了解决这个问题,我们利用卷积运算卓越的特征提取能力来构建神经网络。此外,我们引入自注意力机制模块,提出一种无监督深度聚类方法。该方法通过自动对不同区域的水资源债务水平进行分类,为核算任务提供帮助,从而促进全面的水资源核算。本文提出的方法使用了三个数据集进行验证:美国邮政服务(USPS)、异构人类活动识别(HHAR)和美国计算机协会(ACM)。准确率(ACC)、归一化互信息(NMI)和调整兰德指数(ARI)指标的评估产生了良好结果,超过了K均值聚类、层次聚类和基于密度的约束扩展(DCE)。具体而言,三个数据集上评估指标的平均值分别为0.8474、0.7582和0.7295。
