A few questions and comments

[SaundersMark]

Hello,

I hope you don't mind me adding some comments and questions. I've had a look at your paper and the dataset:

1. I am not clear on how you do the SDR calculations in the contexts of the segmentation models. 5.2.1 gives the fomula:

SDR=10log10 ||m||2
||˜m−m||2

It looks to me that m is the mask and ˜m is the predicted mask. Is that right?

2. Another way would be to calculate SDR based on the audio wave rather than in the frequency domain. However, the lengths of the original and denoised audio waves in the dataset are not always the same and so do this it would seem to be necessary to spend time correlating the signals. The report doesn't mentioned that you did that (but I may have missed it). So presumably, the SDR for the mask-based segmentation models was done for the masks rather than the reconstructed audio?

3. I think that there may be a typo in the formula for IoU in section 5.2.1. Should the denominator be A∪B ?

4. I noticed that some of the masks in the dataset appear to be empty (e.g. XC175650_left,XC462632_left, XC462680_left, XC463223_left, XC463661, XC469469_left, XC49097, XC490972_left, XC496206_left).

Thanks you

Mark
