“…Forecasting is sometimes complicated because the downstream supply chain stakeholders cannot share the information to support the forecast. Many industries such as food, retail, mining, rail, energy, tourism, and cloud computing need to generate more accurate forecasts to provide a better foundation for determining short-term, medium-term, and long-term corporate targets (Bandara, Hewamalage, Liu, Kang, & Bergmeir, 2021). One of the forecasting methods is the qualitative forecasting method which relies on personal judgment, intuition, and subjective evaluation (Chopra & Meindl, 2016).…”

“…Data augmentation for time-series. Prior research on time-series data augmentation includes: (1) large-scale surveys exploring the impact of augmentation on various downstream modalities (Iwana and Uchida, 2021a,b; Wen et al, 2020); and (2) specific methods for particular modalities, including speech signals (Park et al, 2019(Park et al, , 2020, wearable device signals (Um et al, 2017), and time series forecasting (Bandara et al, 2021;Smyl and Kuber, 2016). There is relatively little work exploring how augmentation can impact performance for ECG-based prediction tasks, with prior studies mostly restricted to considering single tasks (Hatamian et al, 2020;Banerjee and Ghose, 2021).…”

“…Discarding rows of data with missing values will not affect most ML and DL models' training processes. However, some models require continuous sequences of data, such as RNNs [57]. In this case, a more in-depth analysis must be performed since time windows with missing values will hinder the performance of the trained model.…”
