Abstract:

To address inefficiency and subjectivity of manual eaves tile dating methods, a Hypergraph-based Eaves Tile Dating method under Data Imbalance Conditions (HETD-DIC) was proposed to provide a more objective assistive tool for archaeological dating. Firstly, a dual-weight computation mechanism was designed, which means that a hyperedge weight computation module was used to aggregate associated node features, so as to generate hyperedge weights, and these hyperedge weights were then used to calculate node weights, which reduced the impact of imbalanced sample distribution. Secondly, a Hyperedge Node Relation Matrix (HNRM) was constructed to establish a feature encoding-decoding channel, so as to enhance the representation capability of nodes. Finally, extensive experiments were conducted to evaluate different models, and UniGIN (Unified Graph Isomorphism Network) was selected as baseline classification model due to its superior performance. Experimental results demonstrate that on the self-built eaves tile dataset, with only 20% of training data used, HETD-DIC achieves improvements of 4.67, 4.55, 4.67, and 5.09 percentage points, respectively, compared to UniGIN in accuracy, weighted precision, weighted recall, and weighted F1-score. It can be seen that HETD-DIC solves data imbalance problem effectively and provides reliable automatic assisted decision basis for archaeological dating.

摘要:

针对人工瓦当年代判别方法效率低且主观性强的问题,提出一种基于超图的数据不平衡条件下的瓦当年代判别方法(HETD-DIC),以提供更客观的考古辅助判别工具。首先,设计双权重计算机制,利用超边权重计算模块聚合关联节点特征生成超边权重,再利用超边权重生成节点权重,降低样本分布不均产生的影响;其次,构建超边节点关系矩阵(HNRM),建立节点特征编码-解码通道,增强节点的表征能力;最后,通过大量实验评估不同模型,并选取表现较好的UniGIN (Unified Graph Isomorphism Network)作为基础分类模型。实验结果表明,在自建的瓦当数据集上,当仅使用20%的训练数据时, HETD-DIC的准确率、加权精确率、加权召回率和加权F1-score相较于UniGIN分别提升了4.67、4.55、4.67和5.09个百分点。HETD-DIC能有效解决数据不平衡问题,为考古断代提供可靠的自动化辅助决策依据。
