Interpreting tensorboard for back translation

Hello,
Training with OpenNMT-tf I’m using tensorboard to keep an eye on progress.
Using back-translation, it’s giving me unusual charts. The BLEU score climbed for 0.5-1 point after 189k training steps.
Could someone interpret these charts and maybe have an insight what is going on?!

Hi,

Is it the increasing evaluation loss that you find unusual?

Gradient I find it unusual, training with just the parallel corpus it used to go down but now it’s going the opposite direction, it’s climbing up!
And yes loss and perplexity are also climbing up even though I’m getting a better BLEU score.
There are two charts for loss one is climbing up and the other is climbing down!

Blue lines are coming from the training and orange lines are coming from the evaluation (see the legend on the left in TensorBoard).

Can you post the full training logs?

I’m training with Kaggle, it doesn’t show the full log, but here is what I can get quickly.

This is data.yml, training data 200k, monolingual cynthatic data 470k:

model_dir: /kaggle/working/run
data:
train_features_file:
- /kaggle/input/abrudata/tgt-train.txt

This is the log that I could get from Kaggle:
