- Abstract summary: Multi-Dimensional Adrial GAN (MDA GAN) is a novel 3-D GAN framework.
MDA GAN employs three discriminators to ensure the consistency of the reconstructed data with the original data distribution in each dimension.
The method achieves reasonable reconstructions for up to 95% of random discrete missing, 100 traces of continuous missing and more complex hybrid missing.

- Abstract: The interpolation and reconstruction of missing traces is a crucial step in
seismic data processing, moreover it is also a highly ill-posed problem,
especially for complex cases such as high-ratio random discrete missing,
continuous missing and missing in fault-rich or salt body surveys. These
complex cases are rarely mentioned in current sparse or low-rank priorbased and
deep learning-based approaches. To cope with complex missing cases, we propose
Multi-Dimensional Adversarial GAN (MDA GAN), a novel 3-D GAN framework. It
employs three discriminators to ensure the consistency of the reconstructed
data with the original data distribution in each dimension. The feature
splicing module (FSM) is designed and embedded into the generator of this
framework, which automatically splices the features of the unmissing part with
those of the reconstructed part (missing part), thus fully preserving the
information of the unmissing part. To prevent pixel distortion in the seismic
data caused by the adversarial learning process, we propose a new
reconstruction loss Tanh Cross Entropy (TCE) loss to provide smoother
gradients. We experimentally verified the effectiveness of the individual
components of the study and then tested the method on multiple publicly
available data. The method achieves reasonable reconstructions for up to 95% of
random discrete missing, 100 traces of continuous missing and more complex
hybrid missing. In surveys of fault-rich and salt bodies, the method can
achieve promising reconstructions with up to 75% missing in each of the three
directions (98.2% in total).

Resting-state MRI functional (rs-fMRI) is increasingly employed in multi-site research to aid neurological disorder analysis.
Many methods have been proposed to reduce fMRI heterogeneity between source and target domains.
But acquiring source data is challenging due to concerns and/or data storage burdens in multi-site studies.
We design a source-free collaborative domain adaptation framework for fMRI analysis, where only a pretrained source model and unlabeled target data are accessible.
