Noise Levels for Training

[yuka-hashiguchi]

Hello. Thank you for sharing amazing repository. I have a question about noise levels for retraining.

Regarding the provided pretrained models, the following descriptions are available

By default, the checkpoint/scene_test_2048_bs3_hor_sigma_001 is used. For very clean or noisy depth data, consider using scene_2048_bs3_rad2_32 or scene_test_2048_bs3_hor_sigma_0025 trained with no or strong noise.

What noise level would be equivalent to when retraining according to the training procedure outlined in the README? I would appreciate any guidance on methods for retraining with strong noise.
