Multi-Task Data Imputation for Time-Series Forecasting in Turbomachinery Health Prognostics

Time-series forecasting is the core of the prognostics and health management (PHM) of turbomachinery. However, missing data often occurs due to several reasons, such as the failure of sensors. These partially missing and irregular data greatly affect the quality of time-series modeling and predictio...
