Deep learning - is a data driven learning method successful at learning non-linear spatial and temporal dependencies from data (LeCun, et al. 2015). [1]
Automatically learn covariate relationships (feature selection) and exhibits ability to generalise to multiple sites (as opposed to Statistical and Dynamical Models).
CNN-LSTM applied to forecasting setting but not to the solar downscaling task.
If successful such a model, driven by a GCM ensemble, will be able to characterise the variability of solar radiation at the regional scale.
Estimate model uncertainty - important to assess future projections and prediction intervals.
