Abstract

Forecasting refers to scientifically determining future value(s). Forecasting can be process-driven or data-driven. Process-driven forecasting tries to explicitly model the physical formation process, while data-driven forecasting develops an input-output mapping just based on a long collection of historical data. Data-driven forecasting has been widely adopted recently because of the availability of gauging data, the ever-increasing computational power, the development of advanced modelling theory and software, and the eschewal of explaining the complex physical formation process that hasn’t been well understood. This talk reports our work on data-driven machine learning forecasting models for hydro, solar and wind, including streamflow, evapotranspiration, solar radiation, and wind speed. Machine learning models can address strong nonlinearity inherent in the input-output mapping for forecasting hydro, solar and wind.
