在當前技術進步的背景下,我們能夠以無前例的方式來收集和分析時序數據,這對各種領域都極具價值。儘管如此,傳統的時序數據分析方法通常依賴於專家的深入知識。這項研究提出了一種基於Shapelet演變圖的新型時序數據分析方法,該方法旨在直觀地捕捉數據的核心模式和特征,而無需專家介入。進一步的比較分析顯示,我們的方法在存在明確的pattern transform情境中表現出色。此外,我們的研究不僅為時序數據提供了全新的分析角度和方法,而且透過與其他基線方法的比較,為我們提供了預測數據集是否存在pattern transform現象的基礎知識。
Against the backdrop of technological advancements, we are now equipped to collect and analyze time series data in unparalleled ways, offering significant value across various fields. However, traditional time series data analysis often leans heavily on expert insight. This study introduces a novel approach to time series data analysis based on the shapelet evolution graph, designed to intuitively capture core patterns and characteristics within data without the need for expert intervention. Further comparative analysis reveals that our approach excels in scenarios with explicit pattern transitions. Moreover, our research not only offers a fresh perspective and methodology for time series data analysis, but, through comparison with other baseline methods, provides foundational knowledge to predict whether a dataset exhibits pattern transition phenomena.
