摘要

。本文提出了一种可视化分析系统，用于分析相邻海域渔业捕捞数据之间的因果关系。利用该系统可以可视化海面温度的分布，从而对海域进行相应的划分。其次，计算各海域的日捕捞效率，并利用收敛交叉映射分析相邻海域数据之间的因果关系。实验结果表明，在两个划分的海底区域中，数据之间可能存在因果关系。此外，还可以参考预测技巧进一步确定因果变量。

Visual Analytics of Causal Relationship Between Fish Catches Data in Adjacent Sea Areas Using Convergent Cross Mapping

. In this paper, a visual analytics system that are used to analyze the causal relationship between ﬁshing catches data in adjacent sea areas is proposed. By using the proposed system, the distribution of sea surface temperature is visualized so that the sea areas can be divided accordingly. Next, the daily ﬁshing e ﬃ ciency in each sea area are calculated and the convergent cross mapping is used to analyze the causality between the data in adjacent sea areas. The experimental results show that the possible causation between the data in two of the divided sub sea areas are detected. In addition, the causal variable can be further identiﬁed by referring to the prediction skills.
