Question about the inputs and the outputs of the model #8

Open OlgaFomin opened 4 years ago

OlgaFomin commented 4 years ago

Hey, First of all your code is great! it worked for me and it is very simple and clear 👍 One question - in your model you used Xin to be spectogram(noisy_voice) and Xout is spectogram(noisy_voice) - spectogram(voice). I didn't understand why did you do the substruction so I tried to take Xout to be spectogram(voice), but then I got underfitted loss. Do you know why that happens?

Thanks again! Olga :)

Hi Olga :)

thanks for the message!

Indeed, I am modelling: spectogram(noisy_voice) - spectogram(voice) as the "noise pattern in noisy_voice spectrogram" to subtract.

The reason I am doing that is that it is much simpler to model the noise to remove in the noisy_voice spectrogram that to directly try to reconstruct the clean voice. This might explain why it was problematic in you case.

Hope it will help,

kind regards,

Vincent
