Bleu scores

[iliasprc]

When i run the inference with the trained model with the evaluation ,the train and the test set i get the following BLEU-4 scores
Train set: 2.0
Dev set: 8.4
Test set: 9.3
How is that possible to get lower scores using the training set?

Hi,

This is quite interesting and have never encountered myself. Would you mind sharing the commands you have used?

[iliasprc]

I have used the following command for the inference model python -m nmt --out_dir=trained_model --inference_input_file=Data/phoenix2014T.test.sign --inference_output_file=Data/predictions_test.de --vocab_prefix= Data/phoenix2014T.vocab --inference_ref_file=Data/phoenix2014T.test.de --base_gpu=0

where every time i change the inference input and ref files to train, test , dev

Thanks a lot, I will investigate to see what went wrong with it.
