About the training/eval loss #1
Comments
I don't have it now, but if you have trained your own model I can tell whether it looks right or not. |
The training loss looks quite different with the eval loss (especially the sil eval loss). Is it normal? 🤔 |
I think this indicates overfitting. Either you add more training data, add data augmentation, or you should stop training before the evaluation loss starts to increase. |
How much data did you use to train the model (I used about 60 hours, 100 speakers)? Besides, why the eval f0 loss much higher (~1.4) than the training loss (~0.09)? Thank you very much. |
I think that was a mistake. I mislabeled the F0 and silence loss for training. I have fixed it. |

Same loss curve. I used data augmentation (e.g. adding reverberation & noise) and the eval sil loss still starts increasing after epoch 30. Besides, when inferencing with sentences which have lots of plosive/fricative consonants, the predicted F0 values are not as good as that trained by @yl4579 . |
What type of data did you use for training? Can you provide me with a small sample? I used the speech data of more than 200 speakers to train the loss to a minimum of 3. After adding data enhancement (background noise), the loss dropped to 4.4 and it became very slow. @Charlottecuc @MMMMichaelzhang |

I do not use the default f0 extractor (e.g. dio / harvest) offered by the author, and turn to other algorithms. Then the sil loss looks much better than before. |
@Charlottecuc did you still apply reverb/noises to the 30% of the dataset? |
Yes. You can add some data aug after maybe 20 epochs. |
Did you use pyin/yin f0 extractor? |
Hi. Thank you for your great work. Could you also share your loss curve? Thank you very much~
