摘要

TTCD框架作为一种开创性的方法被引入，专门针对非平稳时间序列数据的因果发现。传统方法常常难以处理此类数据的复杂性，而TTCD利用了时间和频域注意机制的结合。这种创新方法通过重构引导策略进一步增强，显著提高了因果信号的提取和因果关系识别的准确性。

The TTCD Framework has been introduced as a groundbreaking method for causal discovery specifically tailored for non-stationary time series data. Traditional methods often struggle with the complexities inherent in such data, but TTCD leverages a combination of temporal and frequency-domain attention mechanisms. This innovative approach is further enhanced by a reconstruction-guided strategy, which significantly improves the extraction of causal signals and the accuracy of identifying causal relationships within the data.
