The great thing about this model is that it trains an autoencoder for feature extraction, so the entire test set can be used in training as well. I am still having some trouble trying to figure out how to adapt the single-band model in the papar to the multi-band case we have in our dataset, as both imputation and sample pooling either lose too much information or leave too many NAs. Maybe I should try to directly apply to a single band first and see how it goes.</p>",
