Very short training period from short length of AE embeddings downloaded -> overfitting, but scores still improve. Note also that here the embeddings only overlap with approx. 60-80% of the surface stations we validate on -- the rest are just just 0s instead of the embeddings. This is just due to not downloading the AE embeddings for all stations, this can be done trivially. Thank you to Markus Zehner for making the dataset.
