“…Compared to working on the raw time series data, symbolizing time series with ABBA provides numerous benefits including but not limited to (1) dimensionality reduction, (2) smoothing and noise reduction, and (3) explainable feature discretization. The time series features extracted by ABBA enable fast time series forecasting (Elsworth & Güttel, 2020b), anomaly detection (Chen & Güttel, 2023;Elsworth & Güttel, 2020a), event prediction (Gogineni et al, 2022), classification (Nguyen & Ifrim, 2023;Taktak et al, 2024), and other data-driven tasks in time series analysis (Harris et al, 2021;Wang et al, 2023). An example illustration of an ABBA symbolization is shown in Figure 1.…”
