Saving the best BLEU model

[lvapeab]

When the best model according to bleu is saved (lines 1218-1223), the stored parameters are those that achieved the best error (best_p), not the best BLEU (i.e. the current ones). I think that best_p = unzip(tparams) is missing at line 1220

agree with you

I think 'current_params' should be saved, not the 'best_p'. Because 'best_p' is only about error.
