What is it about?
How to use deep learning to attenuate noise without labelled data? For addressing the similar issue, namely the shear wave noise attenuation from OBN 4C data, this paper introduces a CNN-based workflow to generate the training set without labelled noise-free z-component data and attenuate the noise by using the pretrained network.

Why is it important?
Our examples show that the training set generated by adding the field x-component data to p-component data is representative enough for attenuating the noisy z-component data. Thus, the labelled noise-free z-component data is unnecessary for generating the training set. It indicates that we do not have to use the target labelled data to generate the training set.
